For those of you commuting through Wentzville, brace for lane closures on eastbound Interstate 70 starting next Tuesday. A Missouri Department of Transportation (MoDOT) announcement has confirmed that the right lane between Wentzville Parkway and Route Z will be out of commission every night from 9 p.m. to 5:30 a.m. due to the ongoing Improve I-70 Warrenton to Wentzville Project. Drivers should plan accordingly and expect potential delays.

The closure is a piece of the larger project puzzle, aiming to realign this stretch of I-70 and usher in a new era for local infrastructure, this includes the construction of a new bridge for the Norfolk Southern Railroad above the highway, and though the work may seem like a nightly inconvenience, the lane will reopen each morning as the sun rolls its way into the sky, and these nocturnal adjustments are poised to continue, with the project encompassing this eastern portion of the interstate initially greenlit back in November 2024 with an expected completion timeline stretching from 2025 to 2028.

This road work is part of a major plan to improve Missouri’s infrastructure. Last year, Governor Parson and the General Assembly approved $2.8 billion to repair and expand I-70, adding an extra lane in each direction along nearly 200 miles from Blue Springs to Wentzville. The goal is to reduce traffic and improve daily commutes.

Missouri has major plans to improve travel across the state, and the Improve I-70 Warrenton to Wentzville Project is just one part of it. The goal is to make driving easier and more efficient for everyone who uses these roads.
