ST CHARLES - Motorists using Interstate 64 Daniel Boone Missouri River Bridge can view the designs and the construction schedule for the new bridge at a public open house meeting from 4 p.m. to 7 p.m., Tuesday, November 13 at the State Highway Patrol Headquarters, 891 Technology Drive in Weldon Spring. MoDOT and its contractor, Walsh-Alberici Joint Venture, will display the renderings for the new eastbound I-64 bridge.
The $125 million project will build a new I-64 bridge over the Missouri River to replace the deteriorated bridge built in 1935. The project will include building a new eastbound bridge, removal of the 1935 existing westbound bridge, rehabilitating the 1989 existing eastbound bridge, raising the Spirit Blvd bridge and building a new Chesterfield Airport Road interchange including connecting the North Outer Road to the westbound I-64 on ramp. The project will build a continuous westbound fourth lane from the Chesterfield Airport Road entrance ramp to the Route 94 exit ramp. It will also add a shared use path on the new eastbound bridge connecting the KATY trail to the Monarch Levee Trail.
The new bridge will be built upstream of the existing 1935 westbound bridge and 1989 eastbound bridge. Once complete, the new bridge will carry eastbound traffic. The 1989 bridge will switch to carry westbound traffic, and the 1935 bridge will be demolished.
Construction on the new bridge will begin in late December or early 2013. The majority of construction will be done with minimal impacts to traffic. Lanes on I-64 will remain open but lanes and shoulders will be narrowed. Lanes will be closed on only a few weekends.
The detailed schedule will be available at the public open house meeting and all the materials will be available online at www.modot.org/boonebridge.
