Main Street serves as one of the primary roadways that define a sense of place in downtown Wentzville. Portions of Main Street have been upgraded with new pavement, new sidewalks and streetscape elements. The proposed Main Street Improvements Project will continue these roadway and sidewalk improvements between Hilltop Drive and Church Street to connect recent developments to downtown Wentzville and to improve the overall connectivity and visual appeal of the downtown area.
The project involves roadway and sidewalk design, the incorporation of streetscape elements and on-street parking to mimic Main Street east and west of the project limits. The project will also include design consideration for better handling off-site stormwater that passes through this section of Main Street from areas north of the railroad tracks.
The City of Wentzville will hold an open-house public meeting on July 31, 2024, to discuss the Mexico Road Safety Improvements Project. This proposed project will resurface the existing Mexico Road approximately between Josephville Road to Brookview Way Drive, widen shoulders, re-align the intersection at Hancock Road and add an additional sidewalk from Lakeview Elementary School to Westwind Park Drive.

The public open house is scheduled for Wednesday, July 31 from 4:30-6:30 p.m. at the Wentzville City Hall Board Chambers, 1001 Schroeder Creek Blvd., Wentzville MO.

Route Z Widening and Signalization (Interstate Drive to Perry Cate Boulevard): This project will widen Route Z to a four-lane facility south of Interstate Drive to Perry Cate Boulevard with dedicated left-turn and right-turn lanes at key side streets. Associated with this widening is also the widening/ replacement of the bridge over Peruque Creek to accommodate the four-lane cross-section and the extension of a multi-use trail. The existing three-foot paved shoulders will be replaced with six-foot wide shoulders. In addition to the pavement and bridge widening, this project also will be adding a traffic signal at the intersection of Route Z and Peruque Hills Parkway/ Peruque Ridge Boulevard.
September 2021: The City of Wentzville entered into a project agreement with MoDOT for Cost Share funding and local maintenance funds.
February 2022: The City of Wentzville entered into a project agreement with St. Charles County for use of St. Charles County Road Board Funds.

Phase 2: The Wentzville Parkway South Phase 2 improvement project will build upon the Wentzville Parkway South Phase 1 project by extending Wentzville Parkway South to Interstate Drive. The proposed cross-section will include a two-lane cross-section with curb and gutter and curb inlets along the east side of the roadway and an improved shoulder on the west side that will drain to an open ditch system. The cross-section will allow for future expansion to a five-lane cross-section when traffic demands call for it. The proposed project also proposes to build a 6-foot sidewalk along the east side of the roadway that will connect to the recently constructed Interstate Drive Trail. Also proposed as part of this project is the construction of a grade-separated crossing at the Norfolk Southern Railway.
May 2019: A notice to Proceed was issued to the design consultant.
January 2020: Preliminary Plans completed.
August 2020: Right of Way Plans completed and the land acquisition process has begun.

This project will provide a new outer road system that would link the new interchange at Route 61/Peine Road/Highway P to Wentzville Parkway. The first portion of the outer road has been constructed from Peine Loop Road to Jockeys Run. This project will continue the 2-lane outer road from Jockeys Run to Wentzville Parkway, along with providing dedicated left-turn lanes at key locations. Once this connection is completed, it is anticipated that the access openings will then be eliminated on Southbound Route 61. Elimination of these access openings is a major step toward the reduction of accidents and congestion on Route 61. The project also includes a roundabout at Great Oaks Boulevard. To accommodate bicyclists and pedestrians, a 10-foot-wide multi-use path will be constructed on the west side of the outer road, connecting to the existing multi-use path on Wentzville Parkway. New sidewalk connections at the roundabout will be provided to connect the multi-use path to the existing sidewalk along Great Oaks Boulevard.
Project Location: New outer road from Jockeys Run to Wentzville Parkway. Click here to see a map.
Project updates:
April 2025– County funding for Right of Way acquisition has been approved. The city is working on the acquisition phase currently.
August 2025– Awaiting MoDOT U.S. 61 Safety study and public meeting to determine their priority improvement needs. This will allow the City to determine if the Outer Road is going to be a priority for MoDOT or the City.

Description: A consultant is providing additional analysis to supplement the Wentzville Parkway South Extension Corridor Study completed in early 2013. A corridor alignment that is supported by the local governments and citizens is essential for the corridor preservation process. The intent of the study is to engage the public in developing solutions and to accurately define future construction costs of the project and preserve land prior to future development.
The City of Wentzville in cooperation with the County of St. Charles have coordinated to supplement the initial Study to consider an at grade railroad crossing, improvements to the Wentzville Parkway Interchange, traffic signal optimization and traffic flow improvements from Veterans Memorial Parkway to the traffic signal in front of Home Depot. In summary, the objectives of the Supplemental Study are to establish a feasible, cost effective and locally supported interchange with Interstate 70, determine the feasibility and cost of an at grade crossing for the Norfolk Southern Railroad, and recommend traffic flow improvements of the section of Wentzville Parkway immediately north of the Interstate 70 interchange.
