Scope Of Work

The Ohio Department of Transportation's $228 million I-480 Valley View Bridge project benefits the approximately 180,000 vehicles who utilize the existing I-480 bridges daily. One of the busiest freeway segments in Ohio, deterioration from age and high traffic volumes, necessitated repairs and replacement of the existing bridges concrete decks. To accomplish this task, without creating tremendous traffic delays due to long-term lane closures, the project called for construction of a new 4-lane bridge in the 90-foot space between the existing eastbound and westbound bridges.

With I-480 crossing up to 200 feet above the Cuyahoga River Valley below, conventional crane erection of the new center bridge was nearly impossible. Jacobs designed a new center structure to be erected using gantry cranes spanning between the existing structures. Now, the new center bridge allows for all four lanes of I-480 to be maintained in each direction while repairs are made to the existing bridges.

After repairs to the existing structures are made and the existing concrete decks are replaced, the new center bridge will provide two additional permanent lanes on I-480 in each direction. In addition to the significant bridge design work, the project includes design of reconstructed bridge approach roadways on I-480 to connect the new bridge to the existing highway system, drainage design along I-480 as well in the Cuyahoga River Valley below, traffic control, lighting and ITS elements.
