Interstate 680 Ohio

Interstate 680 Ohio


Interstate 680 branches north from I-76 at Beaver Township in Mahoning County, joining the Ohio Turnpike with the city of Youngstown. The freeway loop runs north between Boardman and the city of Struthers. Entering Youngstown at the Lansingville neighborhood, I-680 makes a sweeping curve west to South Avenue and then turns north to the inner belt freeway system encircling Downtown.

U.S. 62, U.S. 422 and Ohio State Route 193 represent the eastern half of the inner loop, joining I-680 with Youngstown State University and northern neighborhoods of the city. Turning westward to I-80, Interstate 680 meets SR 711, a 1.39 mile long freeway connector linking with both SR 11 north to Ashtabula and I-80 east to Sharon, Pennsylvania. I-680 west defaults onto I-80 west at the separation with SR 11 south by Mineral Ridge.

Exit numbers along Interstate 680 increase from north to south.


The proposed Interstate Route System issued by Ohio in March 1958 inventoried the freeway loop through Youngstown as I-78. I-80 east into Pennsylvania was I-84 and the Ohio Turnpike was I-80. I-78/80 overlapped west to Streetsboro, where I-78 turned northwest along what is now I-480.

Revisions proposed by the Ohio Department of Highways reserved I-280 for the “Akron Bypass”, which had yet to be approved, and assigned Interstate 480 to the connecting loop in Youngstown. However, a request made from the state to the American Association of State Highway Officials (AASHO) on August 8, 1958 resulted in the change to Interstate 680. The original layout for I-77 took the route west from the Cleveland area alongside I-80/90 to Toledo and then north to an overlap with I-75 into Michigan. Ohio suggested that I-77 instead terminate at the junction of I-90 in Cleveland, eliminating what would have been a 118 mile long concurrency with I-80/90. The connecting loop in Toledo would then become Interstate 280, and I-480 assigned to Akron. AASHO entirely agreed with the Ohio proposal in a letter dated August 29, 1958, and on November 10, 1958, the urban Interstate numerology for the Youngtown area was approved.

The proposed route of Interstate 680 appeared on the 1962 County Engineer Map for Mahoning County, Ohio as the Relocation of S.R. 7. The project alignment extended south of the Ohio Turnpike near Five Points to SR 7 (Market Street Extension) midway between SR 165 and Pine Lake Road. This extension was never built.

Bids were opened for the construction of I-680 between Williamson Avenue and Hayes Avenue on the Youngstown Expressway system on September 27, 1960. The state estimated for building this section of I-680 was $1.483,800 and the low bid was $1.298,913.1 A 2.8 mile long section of I-680 south from Midlothian Boulevard (SR 625) in Youngstown to U.S. 224 west of Poland was programmed for an April 18, 1972 bid opening. Construction costs for this segment were estimated at $8.8 million.2 The section included bridges taking I-680 over Mathews Road and overpasses for U.S. 224 and Thalia Avenue above the freeway. Work was originally scheduled for completion on November 30, 1973.3

Prior to 1972, the Ohio Turnpike from Jackson Township, Ohio to Monroeville, Pennsylvania was designated as Interstate 80S. No changes were proposed for I-680 following the renumbering of I-80S to Interstate 76.

The final segment of Interstate 680 opened to traffic on December 15, 1975. Costing $16.2 million, the 10.3 mile long link extended from SR 625 to a partial interchange with South Avenue in Youngstown.4

A folded diamond interchange (Exit 16) with SR 164 (South Avenue) was constructed near the south end of Interstate 680. Construction on the $11.6 million project commenced in April 2018 and the exchange opened to traffic following a ribbon cutting ceremony on November 27, 2019. Work continued nearby on a park and ride site to mid 2020. SR 164 was also widened south to a roundabout built at SR 626 (Woodworth Road) and expanded across the Ohio Turnpike.5
