The Columbia I-70 Bridges Project is an $18 million design-build project to replace the I-70 bridges over Business Loop 70/West Boulevard, Garth Avenue, and MO Route 763/Rangeline Street in Columbia, Mo. Design-build is a project delivery method that combines both the design and construction phases into one contract to save time and resources.
Traffic Impacts Week of May 23
Nighttime single lane closures of eastbound and westbound Interstate 70 expected Tuesday-Thursday due to construction of barrier curbs.
Traffic switch to the new Garth Avenue bridge will take place Tuesday (May 24)evening.
Work will require the westbound I-70 on ramp at Providence to be closed between 9 p.m. and 5 a.m.
Range Line Street
The new“dogbone” interchange at Range Line and I-70 opened Monday, May 23.
The interchange, sometimes called a double roundabout interchange, consists of two tear-shaped roundabouts that join together to form a single roundabout.
Drivers entering the roundabout are reminded they must yield to all traffic in the roundabout before entering. More information about roundabouts, including video animations showing both the old and new Range Line interchange, can be found below.
Business Loop/Creasy Springs
Motorists are asked to continue to use caution at Business Loop and I-70 as flagging operations will be necessary during daytime hours this week.
Road Work Ahead
June 4 – The Range Line bridge slide is tentatively scheduled for the weekend of June 4.

The City of Columbia’s Transit System will provide the following for the duration of the I-70 bridges project for sections that are impacting pedestrian crossings to bus stops on the Business Loop:
Shuttle service from the Parkade neighborhood to connect with either the #9 Purple Route, #8 Light Green and #2A or #2B Gold Routes. While the #9 is the only route that services this area of the Business loop, the city felt it was unnecessarily burdensome to have the customer transfer from a van to the #9 and then make transfers to the other two routes that connect with the #9.
The shuttle will be a scheduled ride and must be called into the city’s ParaTransit line 573-874-7290 by 5 p.m. a day in advance. The customer must state that they want to schedule a ride for the Parkade North Shuttle.
The customer will not be charged for the shuttle ride, but will be charged normal fare when they board one of the three bus routes.
Rangeline, Garth Pedestrian Detours
The sidewalks along Rangeline Street (Route 763) between Interstate 70 and Vandiver Drive in Columbia will remain closed for several months as construction takes place.
Pedestrians and bicyclists are advised to detour around the closed sidewalks by taking Business Loop 70 to Providence Road to Vandiver Drive.
Pedestrians can also use Columbia’s public transit system, COMO Connect, to travel through the area. The Co-Mo Connect Black Connector has stops at Boone Electric Cooperative and Rangline on the south side of I-70 and at Rangeline and Vandiver on the north side of I-70.
The sidewalks along North Garth Avenue between U.S. Route 40 and Interstate 70 will remain closed until next summer as construction takes place.
Pedestrians and bicyclists are advised to detour around the closed sidewalks by taking N. Providence Road to E. Texas Avenue.
Maps of Rangeline and Garth pedestrian detour routes, as well as the Black Connector route, are below.
