Highway Z Widening Public Meeting

Aug. 19, 2025

Join us for an Open House on Monday, Aug. 25, from 4:30-7 p.m. at Wentzville City Hall to learn more about the upcoming Highway Z Widening Project. This project will expand Highway Z between Interstate Drive and Perry Cate Boulevard to a four-lane roadway, add turn lanes at key intersections, widen the Peruque Creek bridge and include a new traffic signal at Highway Z and Peruque Hill Parkway/Peruque Ridge Boulevard. This is a jointly funded project between the City, St. Charles County and the Missouri Department of Transportation. Stop by anytime during the event to view project details and talk with the team.
