November 18, 1925--A report from the U.S. Department of Agriculture/Bureau of Public Roads was approved on this date by the Secretary of Agriculture. Many maps dated 1926 show these tentative routes, including the Ohio Department of Highways (ODH) map of that year. These are the numbers of the proposed routes which were in Ohio: 20 21 22 23 24 25 27 30 40 42 50 52 127.

An oddity on the 1926 ODH map shows US30 shields in two places east of Canton: one on the main road west of Minerva; another on the road into Pennsylvania from East Palestine. Unless one of the shields is erroneously located, the route east of Lisbon must have been a horrible one. No shield is shown in the vicinity of East Liverpool, where the route was first signed in the field.

A route numbered 121 between Cleveland and Lisbon was not shown on the ODH map and was apparently dropped from the Bureau's proposal earlier in 1926. Most of the route locations as described in the report would be recognized on Ohio maps well into the 1970s, with the following exceptions:

US20 was the original transcontinental route ending at Astoria, Oregon, not US30. The proposed terminus for US30 in the 1925 plan was at Salt Lake City. This would change by the time the American Association of State Highway Officials (AASHO) approved the plan.

Also, the first version of US127 terminated at Toledo, but in 1932 was designated for a new route to Cincinnati. The original US127 was renumbered as US223.

November 11, 1926--AASHO accepts a modified plan for the first federal highway system. Numbers in use for Ohio are as follows: 20 21 22 23 24 25 27 30 40 42 50 52 127 322 422

US322 and US422 were addenda to the 1925 plan. US22 was originally proposed to terminate at Cleveland, but was modified to terminate at Cambridge. The Cleveland endpoint was accomplished by two three-digit branch roads which diverged from US22 in Pennsylvania.

Relative to Ohio, the other proposed routes had no drastic changes, although many routes were lengthened beyond her borders. US30 became the route of the Lincoln Highway through much of Ohio, but not nearly as much as one might think. US30 took the southern route across Ashland County, through Jeromesville and Hayesville, and also varied from the traditional Lincoln Highway by reviving the old main market route through Galion, Marion, Kenton, and Lima. Another variation was between East Liverpool and California Hollow Junction in Columbiana County.

The Lincoln Highway crossed four of these original federal routes: 
21 at Massillon; 42 at Mansfield; 23 at Upper Sandusky; 25 at Beaverdam.

Interestingly, US30 was the longest of all the new federal routes, traversing 3472 miles from Atlantic City, New Jersey to Astoria, Oregon. It was rivaled only by US40 (3205 miles from Atlantic City to Oakland, California) and US50 (2856 miles from Annapolis, Maryland to Sacramento, California). US20 in its original form terminated at Yellowstone National Park in Wyoming, only 2542 miles west of Boston. Isn't it odd that two transcontinental routes started at Atlantic City?

Also fascinating is the fact that Ohio had a nice straight run of numbers—20, 21, 22, 23, 24, 25.  For what it is worth, Ohio could boast of having the longest "straight" well into the early history of federal numbers. Later, several new or extended routes gave Texas the right to that claim with an impressive "hand" of numbers from 79 through 85.

1929—The first new number to show up in Ohio's federal scheme was US250, which intersected US30 at Wooster. Although its original termini were at Grafton, West Virginia and Norwalk, Ohio, it was later extended to Richmond, Virginia and Sandusky, Ohio.

Soon to become the intersection of US 250 and US 30.  Lincoln Highway Collection, Transportation History Collection, Special Collections Library, University of Michigan.

1931—The route of US127 between Lansing, Michigan and Toledo, Ohio was renumbered as US223, thus rendering it a branch of US23 instead of US27. A new US127 was designated between Lansing and Cincinnati, crossing the Lincoln Highway at Van Wert.

Also in 1931, US30 between Mansfield and Delphos was split into two routes of equal importance, US30-N and US30-S. This was a carryover from the early days of the Lincoln Highway, when Marion interests, miffed by Henry Joy's quick-trigger 1913 rerouting, created what would become the Harding Highway. US30-N put Bucyrus and Upper Sandusky on an east-west federal route for the first time. Although AASHO despised them, compromising suffixes like these were nothing new. In fact, the original 30-N and 30-S numberings had existed for four years in western Wyoming.

In Ohio, north and south suffixes were in use for US50, and soon there would be a US20-N (later US20-A). Only US40 seemed to escaped the suffix problem for the major east-west routes crossing Ohio.

1932—Three new federal routes show up for the first time on the ODH map of 1932. Routes 6, 36, and 62 are added. Most significant is US6, which meandered from Cape Cod to Colorado. Eventually this route would reach Long Beach, California, traversing 14 states and 3517 miles, overtaking US30 as the longest federal highway. The only other routes that passed through fourteen states were US1, US40, and US50. US30 passes through only twelve states.

In later years, US30 would similarly drop behind US20 and US50 in terms of mileage. Those routes were extended west to the Pacific Coast at Newport, Oregon and San Francisco, California, respectively, and US50 eventually reached the Atlantic at Ocean City, Maryland.
US6 is known as The Grand Army Of The Republic Highway, and is often marked as such in Indiana. It is rare to see such a sign in Ohio, where it is not within state standards to have a "named road" sign displayed on a numbered route.

US36 in its original form was between Indianapolis, Indiana and Colby, Kansas. In its longest, and frustratingly meandering form, it stretched from Cadiz, Ohio to Denver, Colorado, tracing much of the corridor of the old Pikes Peak Ocean-To-Ocean Highway.

At Canton, US62 became the seventh federal route to cross the Lincoln Highway and US30. It traversed 2289 miles from Niagara Falls, New York to El Paso, Texas.

1933—Another new route appeared on the Ohio map the following year. US68 finally escaped the borders of Kentucky, bridging the Ohio River at Maysville, Kentucky before continuing north to Toledo. It crossed the Lincoln Highway at the small community of Williamstown. This route followed in the footsteps of a proposed US125, which would have been a branch of US25 between Findlay, Ohio and Maysville.

1934—Yet another new route was created across Ohio, this time as a branch of US24. US224 was designated between New Castle, Pennsylvania and Huntington, Indiana. It was the ninth route to have a junction with US30 in Ohio. This meeting was at Van Wert, where it shared the path down Washington Street with US127. Thus, Van Wert was the only Lincoln Highway town in Ohio where two federal routes crossed the Lincoln Highway.

1935—For the third consecutive year, a single federal route was added to the federal scheme in Ohio. US35 cuts a diagonal across southwestern Ohio between Charleston, West Virginia and Michigan City, Indiana, and crosses the Lincoln Highway in the middle of nowhere in Starke County, Indiana.

1938—The last federal route to be marked in Ohio was US33, another diagonal route which was more or less parallel with US35. Its termini were Richmond, Virginia and St. Joseph, Michigan, and its junction with US30 is at Fort Wayne, Indiana, where US27 also crosses.

1970s—As the construction of the main routes of the Interstate Highway System neared completion, many of the federal routes became redundant, or were rendered of secondary importance. Because much of US21 and US25 had been superseded in Ohio by I-77 and I-75, respectively, those federal numbers were dropped from the scheme. State Routes 21 and 25 are now the shortened reminders of their past.

Between Mansfield and Delphos, the shorter US30-N corridor was the one improved to become a four-lane highway. Thus, the "cumbersome compromise" of suffixes was finally dropped in November 1973, with US30-N becoming US30 and US30-S becoming State Route 309. Another three-digit number which serves as a reminder of its US30 heritage is State Route 430 near Mansfield.

After US50-N became State Route 550 in southern Ohio, all of the old suffixes had finally been eliminated with the exception of US20-A, which survives west of Toledo. The US30-A designation at Dalton is a mystery of sorts—it shows up with a shield for the first time on the ODH map of 1962, although the Dalton bypass had been built for about ten years.


20 Boston, Massachusetts to Yellowstone National Park, Wyoming—2542 miles
21 Cleveland, Ohio to Yemassee, South Carolina—793 miles
22 Elizabeth, New Jersey to Cambridge, Ohio—490 miles
23 Mackinaw City, Michigan to Portsmouth, Ohio—625 miles
24 Pontiac, Michigan to Kansas City, Missouri—771 miles
25 Port Huron, Michigan to North Augusta, Georgia—792 miles

TRIVIA:  Note that in the original federal scheme, two-digit roads ending in 1 were the major north-south routes, not those ending in 5. Although US25 eventually stretched 1151 miles between Port Austin, Michigan and Brunswick, Georgia, it was considered secondary in its original form to routes such as US21 and US31.

27 Cheboygan, Michigan to Cincinnati, Ohio—516 miles
30 Atlantic City, New Jersey to Astoria, Oregon—3472 miles (crosses 12 states)
40 Atlantic City, New Jersey to Oakland, California—3205 miles (crosses 14 states)
42 Cleveland, Ohio to Cincinnati, Ohio—243 miles
50 Annapolis, Maryland to Sacramento, California—2856 miles (crosses 14 states)
52 Huntington, West Virginia to Fowler, Indiana—343 miles

MINUTIA:  The only federal route in Ohio that terminates in an international boundary is US52, which now ends in the US/Canada line at Portal, North Dakota. Many routes terminate at coastal cities, but this is the only route which ends at our national border.

127 Lansing, Michigan to Toledo, Ohio—77 miles
322 Water Street, Pennsylvania to Cleveland, Ohio—226 miles
422 Ebensburg, Pennsylvania to Cleveland, Ohio—203 miles

In 1912, the State of Ohio's Highway Department published their first map showing numbered roads. That numbering system was the first of five different systems that have been used in Ohio since that time. Part one highlighted the federal numbering system. This part will discuss the other four numbering systems which have been or are being used in Ohio.

The 1912 highway map of Ohio was titled "Map Of Ohio Showing Inter-County Highways" and identified 444 inter-county highways such as ICH #12, known as Cleveland-East Liverpool Road, and ICH #146, known as Mansfield-Wooster Road. Most of the inter-county routes had the character of the latter, simply connecting two cities in adjacent counties. Only several of these routes came close to crossing the entire state. The most notable exceptions were ICH #1, which was the route of the old National Road, and ICH #7, the Ohio River Road.

At the same time that the inter-county highways came into use, a network of Main Market Routes was designated by authority of the state legislators. These routes did cross the state, and in a grid pattern similar to the federal network of highways that would be marked about fifteen years later. More than twenty of these market routes were eventually added to the official state highway map, including Main Market Route No. 3, which supposedly was to be the route of the Lincoln Highway in Ohio. However, the imperfect overlaps rendered here and there by Henry Joy became the source of more than one headache—not only with the seemingly-slighted citizens of Marion and Kenton, but also in Paris Township in Stark County. These stories are more completely told in A History And Road Guide Of The Lincoln Highway In Ohio.

It appears that the system of market routes was used only until 1921, because it disappears on the state map of 1922. Curiously, the market routes went through a renumbering in 1920, and for a brief time, the route of the Lincoln Highway was generally the same as a new Main Market Route No. 2. Other market routes would be familiar to road fans as the future corridors of the Dixie Highway and 3-C Highway, just to name two.

The network of inter-county highways would outlast the main market routes by more than twenty years. It was this set of numbers which first appeared on a state route sign in 1920. Potentially confusing, however, is the fact that the official sign did not show "Inter-County Highway" as part of the text. Instead, the marker had "STATE ROUTE" lettered above the route number, with "OHIO" appearing below. Supposedly the story goes that "INTER-COUNTY HIGHWAY" took up too much space on the sign. This first sign was actually no more than black and white paint on a utility pole. By the way, there is no evidence that any market route was ever signed—it appears that the number was merely a paper designation.

The state route/inter-county language is again potentially confusing because in 1923, Ohio's third system of numbered highways was designated. This system provided the original framework of the same state route system which survives today. The confusion lies in the fact that the Department of Highways continued to use the old inter-county highway numbers for office purposes until 1947. Thus, all highway projects in that era are referenced to the inter-county highway number (and state route number of 1920-1922) and not the new state route number established in 1923. This is important to consider when researching old bridge and roadway plans. By the time those original numbers were discontinued in 1947, over 1000 inter-county highways had been designated.

Click to view.  The legend of the 1923 map (click left) shows the first Ohio route sign to be fabricated and placed on a post. Although the colors of the sign are not specified here, by 1926 it is known that the signs were black on yellow. In later years, the signs would revert to the black on white which is still the standard today.

With this new system, the total of numbered roads in Ohio was reduced to 223. However, it did not take long for the system to be expanded, for by 1935 and 1936, the highest numbered route on the map was State Route #386. Then, an apparent burst of energy must have struck the highway department. Almost magically, more than 150 new routes appeared on the 1937 map, with numbers ranging in the 500s, 600s, and 700s. Note that only half the available numbers were used here. Many but not all would come into use soon thereafter.

It is not known why the 400 series of numbers was skipped. John Simpson, who maintains an impressive web site he calls The Unofficial Ohio State Highways Web Site, speculates that the 400 series was "reserved for a new state freeway or toll road system, much like Ontario's 400 series highways.

Although it is not easily discerned, there does appear to have been some method to the madness of numbering all these state routes. Routes 1 through 10 were definitely the most important routes, as witnessed by the fact that most would soon become routes of the federal highway system. The ten routes were also set apart by having a rectangular "named road" sign above the Ohio shield. The numberings had a mixture of logic and randomness. State Route 1 remained the old National Road, and State Route 7 remained the Ohio River Road, and were the rare exceptions of routes which carried over their previous inter-county numbers. It also made sense that the 3-C Highway (Cleveland/Columbus/Cincinnati) was numbered State Route 3. The route of the Lincoln Highway became State Route 5, the Dixie Highway was State Route 6, and the Harding Highway was State Route 10. State Route 11, which did not carry the auxiliary sign, also crossed the state and formed the backbone of what would become U.S. Route 35.

Starting with State Route 12, tracing the numbering system becomes a fascinating adventure. It is likely that someone in authority merely sat down, or sat someone down, at a drafting table or desk and laid out the map of what would become the 223 routes. This privileged individual then put numbers on the map in whatever way made the most sense at the time. John Simpson calls it a "clustering" system.

Note that the original State Routes 12 through 16 all radiated from Cleveland. Similarly, Routes 19 through 21 from Columbus. It seems that longer routes from the largest urban areas were given low number priority. Numbers such as 79, 80, and 81 were used for major routes which criss-crossed the state without entering the biggest cities.

At this point in the numbering scheme, it appears that the mapmaker turned his pen to the northeast corner of the state, and commenced to fill in numbers for all the minor routes nearest the state's perimeter. He worked his way around the state in a counter-clockwise direction, starting with numbers in the 80s in the northeast counties. Thus, numbers in the 90s abounded in the north central part of the state, numbers in the 100s in the northwest corner of the state, numbers in the 110s in the west central counties, and so forth. By the time the mapmaker had circled back around to eastern Ohio, he had exhausted all the numbers into the 150s. It appears he then made another pass across the state, filling in the numbers for routes of similar importance which were closer to the center of the state.

It is obvious that by the time the mapmaker reached the 200s, he was labeling the most minor routes and connecting roads. Other minor routes, connectors, and access roads to state parks are prominent in the 300 series. Note the numbering similarities for routes in the vicinity of Indian Lake, Lake Loramie, and Grand Lake St. Marys. As discussed above, numbers in the 500 through 700 series burst onto the 1937 map, but seemingly in a scattershot fashion, although some clustering is evident.

The fourth numbering system effecting Ohio was the first one created by federal government. This was the federal highway system shown on the Ohio map of 1927, and included U.S. Route 30 in the corridor of the Lincoln Highway. Again this is a story more completely told in A History And Road Guide Of The Lincoln Highway In Ohio, but suffice it to say that the first version of U.S. Route 30 did not completely follow the Lincoln Highway route traced by State Route 5. The most notable exception is between Mansfield and Delphos, where the original version of U.S. 30 followed the Harding Highway, putting Galion, Marion, Kenton, and Lima back on a route of national prominence after each had been methodically eliminated from the route of the Lincoln Highway.

The federal numbers for Ohio were more specifically discussed earlier, but it is worth noting that these new numbers forced the state highway department to renumber many of the state routes that appeared on the 1923-1926 maps. It was this renumbering that began the unraveling of whatever order had existed in that state route numbering scheme.

More unraveling would occur as the Interstate Highway System was completed. This system, now almost fifty years old, would be the fifth system of numbers for highways in Ohio. This time, however, the state was slower to make a decision to renumber duplicate routes. Despite the opening of bits and pieces of I-70 and I-75 during the late 1950s, State Routes 70 and 75 retained those designations until 1962.

Today there are more than 550 numbered routes in Ohio. Of these, 22 routes are survivors from the federal highway system, and 21 bear the blue and red interstate shield. Numbers in the 400 and 800 series can now be found on the Ohio map. Numbers in the 400s are generally segments of previous routes which have been replaced by major improvement projects. For example, routes 421, 423, 424, and 430 are all parts of previous federal highways 21, 23, 24, and 30. Numbers in the 800s seem to be the choice for the highway department's newest additions. In 1969, State Route 8 south of Canton was renumbered as State Route 800. Newer numberings such as 807 and 835 imply a relationship with nearby State Route 7 and U.S. Route 35. Other new numbers in the 800 series, including several bridges across the Ohio River, have less obvious ties to previous numberings.
