COLUMBIA, Mo. (KMIZ)
Construction work is expected to begin this month for an improvement project at the Grindstone Parkway/Highway 63 interchange in Columbia, the Missouri Department of Transportation wrote in a Tuesday press release.
Off-road work that will not impact traffic begins this month, the release says. Roadwork that would cause traffic impacts begins in March and is expected to last through July 2026, the release says.
The release says the project will address congestion in the area and increase accessibility for cyclists and pedestrians.
Some of the improvements include redesigned on-and-off ramps for northbound Highway 63, a realignment of Lenoir Street, widening and realigning Grindstone Parkway/New Haven Road east of the highway and a new traffic signal.
