The ongoing I-70 overhaul project in Wentzville will eventually expand the highway to six lanes, but the construction process will bring temporary disruptions and delays for local drivers.O'Fallon TodayThe Missouri Department of Transportation's massive I-70 rebuild and widening project, which will eventually expand the highway to six lanes between Wentzville and Blue Springs, is already moving forward with bridge demolition work in Columbia. Crews say they are ahead of schedule on reopening lanes there, a crucial early step in the long-term project that will impact Wentzville drivers.
Why it matters
The I-70 overhaul is a major infrastructure project that will significantly impact traffic and commutes in the Wentzville area once completed. The early progress on bridge demolition in Columbia indicates that MoDOT is making strides on the overall project, which is an important development for local residents and businesses who rely on the highway.
The details
MoDOT's crews are currently working on demolishing bridges as part of the I-70 rebuild in Columbia, located east of the Wentzville area. This bridge demolition work is a key early step in the larger project to widen I-70 to six lanes between Wentzville and Blue Springs. Crews say they are ahead of schedule on reopening lanes in Columbia, which will help maintain traffic flow as the broader overhaul continues.
- MoDOT began bridge demolition work on I-70 in Columbia in early 2026.
- Crews expect to have lanes reopened ahead of schedule in the coming weeks.
The players
MoDOT
The Missouri Department of Transportation, the state agency responsible for maintaining and improving the state's transportation infrastructure, including the I-70 overhaul project.
Wentzville
A city in St. Charles County, Missouri that will be impacted by the I-70 widening project, as the highway runs through the area.
What’s next
The next major milestone for the I-70 overhaul project will be the start of widening work between Wentzville and Blue Springs, which is expected to begin later this year once the bridge demolition in Columbia is complete.
The takeaway
The early progress on the I-70 overhaul project is an encouraging sign for Wentzville drivers, who will eventually benefit from the expanded highway capacity once the long-term work is finished. However, the project will likely cause disruptions and delays during the construction phase, underscoring the need for patience and planning ahead for commuters in the area.
