Stay informed about the latest updates on road construction, transportation and infrastructure improvement projects in Wentzville to ensure you are aware of ongoing and upcoming work in your area. These projects may be completed by the City of Wentzville, St. Charles County, MoDOT or a combination of entities.

Crystal Creek Slab Replacement

Beginning Friday, May 29, the Street Department will begin concrete slab replacement work along Crystal Creek Parkway. The project is expected to last several weeks.

During construction, one direction of traffic will be closed for the duration of the project. In the first phase of work, traffic will still be permitted to enter Crystal Creek Parkway. Motorists will be detoured to exit via Crystal Crossing Lane to Great Oaks Boulevard.

Detour signs will be posted throughout the area to assist drivers. A detour map is included below for reference. Residents and motorists are encouraged to use caution and allow for additional travel time while work is underway.

Blasting at Highway Z and I-70

As part of interstate widening and interchange improvements along the westbound I-70 off-ramp at Highway Z, MoDOT will be conducting controlled blasting beginning May 11. This is expected to continue for the next 3-5 weeks during daylight hours.

What to expect:

  • 1–3 controlled blasts per day
  • Rolling roadblocks on I-70 and Route Z
  • Short-duration local road closures
  • Audible warning signals prior to blasting
  • Brief vibrations may be felt nearby

This work is part of the reconstruction of Interstate 70, adding a third lane in each direction, and the realignment of I-70 between Wentzville Parkway and Route Z.
