LUC 280-2.96 Maumee River Crossing Project

The new Maumee River Crossing Project was part of the widening and replacement of the I-280 route. This route connects the Ohio Turnpike and I-75 in Toledo, Ohio.  The project features an elevated bridge approximately 8,700-feet long, extending from north of Seaman Street to the Greenbelt Parkway. It also includes a signature cable-stay, main-span section over the Maumee River.  The Figg Bridge Engineers of Tallahassee, Florida designed the cable-stay and elevated bridges.

DLZ was responsible for the subsurface investigation for the project as well as the roadway design and surveying services.  The subsurface investigation consisted of 117 borings, many of which extended to depths greater than 100 feet.  At the location of the main pylon in the river, we drilled five borings to bedrock.

The geotechnical engineering for the project included the foundation recommendations for the bridge, as well as the design and construction recommendations for the embankments and roadways on the project.  Of particular note, one of the embankments was to be constructed in a narrow right-of-way over soft, glacial lake deposits.  Because the narrow right-of-way precluded an embankment with flat slopes, the DLZ team recommended a construction procedure using wick drains, wire-faced MSE walls, staged construction, and instrumentation.
