In Lucas County, Ohio, work continues on multiple phases of the I-475 improvement project. The Ohio Department of Transportation (ODOT) is overseeing the latest effort, a $102 million undertaking that includes building a highly anticipated interchange at U.S. Route 20A in Maumee in northwest Ohio. “This project is one of several identified in a strategic plan by the Toledo Metropolitan Area Council of Governments [TMACOG] in the late 2000s, to prioritize improvements for the entire length of I-475 in the Toledo Metropolitan Area,” said ODOT District 2 spokesperson Kelsie Hoagland. “The study laid out certain recommendations, some of which have been constructed, and some that are yet to be developed.” This segment of I-475 overlaps U.S. Route 23, connecting travelers north to Michigan and serves as the major interstate

The pavement on the project is being completely replaced. This includes removal of the existing pavement and installation of new drainage features, followed by cement stabilizing the subgrade for the new pavement.
alternate to I-75 and I-280. “The route is also a major thoroughfare for local traffic, connecting several suburbs in greater Toledo,” Hoagland explained. “The project is constructing a new interchange at U.S. Route 20A, which will provide better access to a developing commercial/business/industrial corridor. Daily traffic on this segment of I-475 is more than 70,000.” I-475 improvements include the widening of I-475 from two to three lanes and covering a 5-mi. stretch between Airport Highway and the Maumee River crossing. In addition to constructing a diverging diamond interchange (DDI) at Route 20A and I-475, crews must resurface a portion of U.S. Route 24 and improve access to the industrial corridor. “Construction is going well, but there have been challenges,” said Hoagland. “Challenges with conflicts in the constructability of maintenance of traffic plans designs have
been a factor, but also with crashes. We have had many crashes in this zone, and regular traffic delays as a result. The primary cause is high speeds and following too closely. There is no room for error in this zone.” The existing configuration provided two lanes in each direction, which is maintained most of the time, but during construction, shoulders are eliminated, and lanes are narrowed. Various short- and long-term ramp closures are necessary and under way. Work began in July 2022 and should be completed by December 2024. Kokosing Construction Company Inc. serves as the prime contractor. “Kokosing is a hub in the northwest Ohio region, allowing them to be familiar with the area, and they have completed other large projects with ODOT in the past,” said Hoagland. see KOKOSING page 4
