Interstate 475 Ohio

North End
South End


Interstate 475 is a bypass and commuter route in the Toledo metropolitan area. Looping west from I-75 at Perrysburg, the freeway crosses the Maumee River into the city of Maumee. Proceeding north. I-475 heads through Holland along the west side of Toledo to connect directly with the U.S. 23 freeway to Ann Arbor, Michigan near Sylvania. The remainder of I-475 travels east back to I-75 near Downtown Toledo.


Interstate 475 first opened as a section of relocated U.S. 23 between West Central Avenue (U.S. 20) and Monroe Street (Ohio 51) in Sylvania. A ribbon cutting ceremony was held on November 2, 1962 for the roadway that cost $5 million. Traffic began use on it a few days later once sign and guard rail installation was completed. The highway tied into a preexisting section of U.S. 23 expressway leading north into Michigan.1 That stretch of U.S. 23 north to Dundee opened to traffic on December 11, 1959 at a cost of $8.4-million.2

The two spans carrying Interstate 475 across the Maumee River were constructed from 1962 to 1964 at a cost of $1.4-million. The bridges were unique in that they curved on both the vertical and horizontal planes, with the vertical element banked at 0.025 feet per lineal foot. Separated by 84 feet, the seven-span bridges are supported by 25 foot high piers totalling 1,481 feet in length.3 The bridges opened along with I-475 southeast from U.S. 24 (Anthony Wayne Trail) to U.S. 25 (Dixie highway), south of Perrysburg, in Fall 1966. The 2.8 mile segment extending east from the bridges to U.S. 25 was built at a cost of $3.1 million and completed in 1964. The $2.6 million extension northward to the interchange with U.S. 24 was under construction from October 10, 1964 to November 30, 1966.4

The freeway north from U.S. 24 to U.S. 20 (West Central Avenue) was dedicated on November 21, 1968. The 8.3-mile stretch of I-475 cost $12.5-million.5 The 2.1-mile section of I-475 between Corey Road (Exit 15) and Secor Road (Exit 17) was constructed from Spring 1968 to November 1969 for $6.7-million.6 This segment tied into the final link of I-475, the mile long freeway between Secor Road and Douglas Road. Bids for this portion were received on June 17, 1969 with completion anticipated for November 30, 1970.7 The Northwest Expressway was completed on December 15, 1970. The northeast end of I-475 defaulted traffic onto I-75 southbound, as the segment of I-75 north was still under construction.8

Cardinal directions on I-475 change from east/west to north/south once the freeway turns southward along side U.S. 23 at Sylvania. Photo taken 09/02/05.

Under a 10-year $5 billion transportation improvement plan announced August 6, 2003 by Governor Bob Taft, Interstate 475 was expanded from four to six lanes between Corey Road (Exit 15) southward to the Maumee River crossing. Additionally the northern exchange between I-75/475 was reconstructed and improved. A three-year, six-cent hike to the state’s motor fuels tax covered the costs of these projects.9
