Work Begins on Columbia I-70 Bridges

I70 Bridges Kickoff

Work is underway on replacing the Interstate 70 bridges at Business Loop 70, Garth Avenue and Rangeline Street.

Although there will be only a few temporary overnight lane closures of

I-70 during construction, traffic is expected to move slower through the construction area.

Other lane closures will occur at Rangeline, Garth Avenue, Creasy Springs, the South I-70 Outer Road and the intersection of West Boulevard and Business Loop 70 throughout the project. Many of these closures will happen at night and will not affect daytime commutes.

While road closures have been designed to keep traffic disruptions to a minimum, there still will be times when drivers will have to detour around the work. Koestner said MoDOT and contractor Emery Sapp will provide ample notice of any lane closures so drivers will be prepared.

An average of 80,000 vehicles a day cross the I-70 bridges at these three locations. The structures date back to 1957 and are in poor condition, but safe for travel.

The $18 million design-build project, which also includes building new roundabouts on the north and south sides of I-70 at the Business Loop 70/West Boulevard interchange and at Rangeline, has an aggressive construction schedule. To speed up the work, several of the new bridges will be built next to the existing structures and slid into place. The project is scheduled to be complete by Oct. 1, 2016.

Changes to 50/63 near Lafayette Interchange
(Effective 8/27/15)

Beginning Thursday, Aug. 27, work on the new Lafayette Interchange project in Jefferson City will bring changes for motorists traveling both directions on U.S. Route 50/63 in Jefferson City.

Currently, only one westbound lane of Route 50/63 is open near Lafayette Street. At 5 p.m. on Aug. 27, both westbound lanes of Route 50/63 will be opened and traffic will be diverted down the new Lafayette off ramp. Traffic will continue across Lafayette Street, travel up the new on ramp and back onto westbound 50/63. Motorists currently have access to

Lafayette Street at this location, but on Aug. 27 access to Lafayette will be closed. This configuration will remain in place until June of 2016. This will allow workers to continue construction of the new interchange, as well as work on the Route 50/63 bridge over Lafayette Street.

Due to the new westbound configuration, the on ramp from Clark Avenue to westbound 50/63 will remain closed until June of 2016.

Also on Aug. 27, the eastbound lanes of 50/63 will be reduced to eleven feet through the work area near Lafayette Street. This alignment will remain in place until the end of this year.

Two lanes will be open in each direction on 50/63 during the work, but traffic may move slower than normal during peak travel times. Motorists are encouraged to seek other routes, if possible.

The work is taking place as part of the Lafayette Street interchange project, a two-year, $20.3-million project that includes building a new interchange at Route 50/63 and Lafayette Street. A lane will also be added in each direction on the Whitton Expressway from Monroe Street to Lafayette Street and from Lafayette to Clark Avenue. The project also includes the improvement of six bridges along the corridor.
