Baker is a subconsultant to Richland Engineering on the project for the Ohio Department of Transportation (ODOT).
Specifically, Baker will provide design and plan production for the design of the main viaduct superstructure as well as public involvement and waterway permit services together with utility and agency coordination.
The new structure will be approximately 1,219m long and has an estimated construction value of approximately US$350 million. Baker’s design fee, including final design services scheduled for completion in June 2013, will be approximately US$3 million.
The new bridge will be an uncommon structural type, with a steel delta frame. It will have a number of long spans with very tall piers. Among the challenges will be making the new structure compatible with the new westbound I-90 Innerbelt Bridge, which is currently under construction. Baker will assist ODOT with significant outreach and coordination with the local communities.
