Ohio’s Timeline

Feb. 15, 1905
The Ohio Department of Highways begins operations. The four-man office had a $10,000 annual budget and was created to study the state’s roads and the science of road construction.

Inferior conditions on predecessors multi-state roadways, like the National Road, seen here in Belmont County Ohio in 1914, demonstrated the need for modern highways.


July 7 – Sept. 6, 1919
A United States military convoy makes a 62-day journey from Washington, D.C. to the Presidio Army Base in California, with Lieutenant Dwight D. Eisenhower serving as an observer. The delays to the convoy caused by inferior roads and bridges made an impression on the young army officer.


1933
The Department of Highways trains and organizes the first Ohio Highway Patrol to help prevent rising fatalities due to auto accidents. The first patrolmen assume their duties before the end of the year.


1945
General Dwight D. Eisenhower sees the advantages of the “Reich-autobahn” or “National Auto Road” in Germany at the end of World War II.


1947
The Ohio Department of Highways has a record construction year, awarding 422 contracts and spending $38 million on new construction and $4 million on maintenance.


Jan. 7, 1954
President Dwight D. Eisenhower names attaining a safe and adequate highway system a priority in his State of the Union Address.


June 29, 1956
President Eisenhower signs the Federal Aid Highway Act into law, designating highways for each state to build with federal assistance to create a system of highways 41,000 miles long.

1957
Ohio’s Department of Highways officially begins construction of the 1,500 miles of the interstate system designated for the state in the Federal Aid Highway Act.


1958
Ohio is ahead of most other states in creating interstate highways — spending more on roadway construction than New York or California.


1960
Ohio remains ahead of schedule in its interstate construction program with 522 miles of interstates open to the public.


1962
Ohio has 684 miles of interstates open.


1965
Federal funds are made available for highway beautification projects. The Ohio Department of Highways takes a leading role in this national initiative, creating a new Design Services Division to oversee rest areas and landscaping along thousands of miles of state and interstate roadways in Ohio.


1968
President Richard Nixon signs a new Federal Aid Highway Act into law, re-authorizing more than $4 billion dollars to the highway fund and adding more than 1,400 miles to the system.


1970
Ohio has more than 1,000 miles of its planned interstate open.


1971
Ohio has constructed all but 167 miles of its interstate highways.

September 1972
Following a national trend to consolidate different modes of transportation under one agency, the Ohio Department of Highways officially becomes the Ohio Department of Transportation (ODOT).


1975
Interstate 270 in Columbus, Ohio is completed.


1976
Interstate 70 is completed through Ohio, making it the state’s major east/west corridor.


2000
Ohio must plan to expand its 1960s transportation system to meet 21st century needs. Ohio’s interstate highways are approaching their 50th anniversary and are greatly in need of expansion and reconstruction. Truck traffic alone has grown 90 percent in the last 25 years and will grow in Ohio by at least another 60 percent in the next 20 years.


August 2000
ODOT begins the Cleveland Innerbelt Study to develop a comprehensive strategy to rebuild portions of Interstate 71, Interstate 77 and Interstate 90 into downtown Cleveland. Of primary importance to the city, these roadways have nearly reached the end of their designed lives and must be systematically replaced. Web site


March 2002
Work begins on the Interstate 280 Veterans’ Glass City Skyway Bridge project in Toledo, replacing the outdated Craig Memorial lift bridge. At a construction cost of $220 million, the Veterans’ Glass City Skyway Bridge is the largest single construction project in ODOT history. Web site


March 2002
ODOT initiates The Interstate 75/Interstate 475 Interchange upgrade study to evaluate these existing interstates, their safety needs and develop potential improvements to these heavily-used roadways in the Toledo area.


June 2002
ODOT begins a study on solutions to the congestion, traffic delays and safety hazards of the Interstate 70/Interstate 71 south Innerbelt corridor in downtown Columbus. Commonly called "the downtown split," the corridor is the site of 27 percent of all I-70/I-71 freeway accidents in Franklin County and one of the top accident and congestion locations in the state. Web site


Aug. 5, 2003
Governor Bob Taft announces his historic Jobs and Progress Plan – a $5 billion, 10-year investment to rebuild Ohio’s urban interstate networks, address high-crash locations and complete the state’s rural macro-corridors to connect rural areas. Web site


The reconstruction and completion of a new stretch of Columbus' Interstate 670 in 2003 represented the final link of the interstate highway system as planned for Ohio in the 1950s.

Sept. 19, 2003
The final project of the Interstate 670 Spring-Sandusky Interchange in Columbus opens, completing the originally planned interstate highway system in Ohio, almost 50 years after construction of the interstate system began. Web site


2004

ODOT completes the Cleveland Innerbelt Plan of alternatives for replacing worn down interstates in downtown Cleveland. ODOT continues its campaign to seek public opinion on how to best approach the process. ODOT hopes to begin construction of the first phase in 2009.


May 2004
ODOT begins the Thru the Valley project to widen and reconstruct Interstate 75 in southwest Ohio to improve safety, increase mobility and ease congestion in the area. Web site


May 2004
ODOT completes a six-month, North Central Outerbelt study to find solutions on reducing congestion and accidents on Interstate 270 at the interchanges of State Route 315, U.S. Route 23 and Interstate 71 on Columbus’ north side. The interchanges serve between 10 to 20 percent more traffic than they were designed to handle and experience more than 500 accidents a year. Construction of the first phase of the North Central Outerbelt begins in 2006.  Web site


June 14, 2004
ODOT begins the Northeast Expressway Transformation (NExT) project – the largest project ever in central Ohio – to rebuild the State Route 161 interchanges at Interstate 270 and Sunbury Road, including 17 bridges, 18 ramps and five miles of highway. Web site


September 26, 2005
ODOT partners with the Kentucky Transportation Cabinet and begins a study to improve congestion and safety issues on the Brent Spence Bridge and its approaches through the Greater Cincinnati/Northern Kentucky area.


2006
ODOT is now responsible for the 7th largest highway system in the nation. Ohio’s highways also have the 5th greatest volume of traffic; make up the 4th largest interstate system; have the 3rd greatest value of truck freight and contain the 2nd largest inventory of bridges.
