The St. Charles County Highway Department has road construction projects underway to improve traffic flow, reduce congestion, and improve safety at two high-volume intersections, with more road improvements planned in the near future.
CENTRAL SCHOOL ROAD AND ST. PETERS HOWELL ROAD: Just north of Route 364 in the St. Peters area, improvements to widen the intersection of Central School Road and St. Peters Howell Road in all directions have begun. Central School Road will have an additional turn lane and an additional drive/merge lane on both sides of the intersection. St. Peters Howell Road will have an additional left turn lane to serve drivers accessing the Route 364 corridor.
A $1.6 million contract has been awarded for this construction, and it is expected to be complete by June 2023.
ROUTE Z AND ROUTE N: In the Wentzville area, south of Interstate 70, the intersection of Route Z and Route N is being relocated to the east to improve the alignment of the intersection. Additionally, the new intersection will be expanded in all directions and a traffic light will be installed.
A $5.8 million contract has been awarded for this construction, and the work is anticipated to be completed by late 2023 or early 2024.
Both road improvement projects are funded by the voter-approved St. Charles County ½-cent Transportation Sales Tax, along with Federal Highway Administration (FHWA) Congestion Mitigation and Air Quality Improvement Program funding.
