MoDOT announced a major traffic shift on the eastbound lanes of Interstate 70 at Wentzville Parkway. Kicking off at 9 p.m. on Friday, this change is part of the larger Improve I-70 Warrentton to Wentzville Project, as per a MoDOT statement. Drivers should plan for possible delays, as the realignment, beginning just west of Wentzville Parkway and winding through the I-70 curve near Route Z, calls for narrow lanes confined to 11-foot widths.
The $2.8 billion state budget for FY2024 includes a major project to expand I-70 by adding a third lane in each direction along nearly 200 miles from Blue Springs to Wentzville. The project, approved by the legislature and signed by the governor, will run through 2028. As part of the work, a barrier wall will be installed on the right shoulder, leading to lane reductions and traffic shifts that will last through 2026.
MoDOT has noted that the construction schedule will depend on weather conditions. Drivers should expect delays and narrower lanes throughout the project. Once completed, the expansion is intended to increase capacity, improve safety, and provide smoother travel across central Missouri.
