Columbia I-70 Bridges Design-Build Project
How do you keep 80,000 vehicles a day moving on a cross-state interstate while replacing a number of aging and deteriorating bridges and improving two major interchanges?
That’s the challenge the Missouri Department of Transportation faced with the $17.5 million Columbia I-70 Bridges Design-Build project. The project included replacing bridges on Interstate 70 at Garth Avenue, Range Line Street and Business Loop 70/West Boulevard in Columbia. Improving the interchanges at Range Line Street and Business Loop was also part of the design-build project.
Sliding bridges, dual-lane roundabouts, and a dog-bone interchange were just some of the components of this fast-paced, innovative project. Several of the new bridges were built next to the existing structures and slid into place to minimize closures on I-70 and affected city streets. Completed in August 2016, drivers are now able to enjoy traveling a safer route to their destinations.
