Wilmer Road Improvements

Wilmer Road Improvements

Project description: 

The project involves Wilmer Road between Interstate Drive and the Peruque Creek Bridge.  This section of Wilmer Road is a country road that now serves as a collector roadway based upon recent residential development.  As such, these project limits require updating to serve the current and anticipated use of Wilmer Road.

The current typical section of Wilmer Road between Interstate Drive and the Peruque Creek Bridge is a bidirectional, two-lane roadway with 11-foot-wide lanes and no shoulders.  The drainage for Wilmer Road uses roadside swales that leave little separation between the travel lane and the downward slope into the swale.  In addition, the southern portion of the Wilmer Road project limits pass through the lowlands along Peruque Creek, where the headwalls of two culverts are situated immediately adjacent to the edge of the driving lane.

The existing vertical curvature of Wilmer Road presents sight distance concerns for two of the residential subdivisions near the north end of the project limits. 

The proposed Wilmer Road Improvement Project aims to make Wilmer Road a safer road for motorists and to provide space for cyclists to safely use the Wilmer Road corridor.  Specifically, the primary aspects of the Wilmer Road Improvement Project include:

1.     Establishment of a 32-foot-wide pavement typical section to include:

·        Two 11-foot-wide lanes

·        Five-foot-wide shoulders on both sides of Wilmer Road

2.     Vertical curve adjustments to improve sight distance, particularly between Wolf Run Lane and Wilmer Valley Drive

3.     Pavement repairs and resurfacing

4.     Re-establishment of roadside drainage swales

5.     Culvert extension and/or replacement to accommodate the wider pavement cross-section

6.     Implementation of signage and/or guardrail, as appropriate, to improve roadside safety

7.     Study of the impacts of the Wilmer Road widening on the Peruque Creek regulatory flood plain and floodway.

December 2023 – City selected design firm.

December 2024 – Received Preliminary Plans.

February 2025– City applied for MoDOT funding for the project. 

Summer 2025 – The City was notified that we were unsuccessful in obtaining MoDOT funding for the project.

North Point Prairie Road Study

This study will investigate and develop a potential transportation improvement plan for North Point Prairie Road from North Service Road to Highway 61. This high-level transportation analysis will review development to date, future projections, and the impact of a completed David Hoekel Parkway as part of the study, which will lead to the development of conceptual plans that will help guide future improvements along North Point Prairie Road. 

Project Schedule

The concept study for North Point Prairie Road began in late 2024 and will end in early 2026. The study will result in a recommendation to the Board of Aldermen that includes the scope and cost of the first phase of improvements to North Point Prairie Road, and the study will be used to support the City’s applications for federal and county funds to support this project.

The Phase 1 project is identified in the City’s five-year Capital Improvement Plan. Construction of the Phase 1 improvements is anticipated in 2030.

The City hosted a public open house on Monday, October 20, to discuss the various issues facing North Point Prairie Road and some ideas for how to make improvements. The plans and graphics Presentations at the meeting are included in the links below.

Background Information

The open house included graphics that introduced the study and provided information about traffic volume, crash history, and the anticipated timeline for the start of improvements along North Point Prairie Road. Click Here

Overall Approach to North Point Prairie Improvements

The demands that a growing community are placing on North Point Prairie Road are outgrowing what North Point Prairie can safely provide. As the City envisions safety improvements (like adding shoulders and improving visibility), this study will help to explore the scope, benefit, and cost of adding other improvements, such as sidewalks or a shared-use path. Two general approaches were reviewed through this study

Alternate Number One

A more suburban approach – Reconstruct North Point Prairie Road according
to the City’s standards for a collector roadway, which would include a center turn lane and sidewalks on both sides of the street. A close comparison would be the section of Peine Road between West Meyer Road and Splash Station. See plans here.

Alternate Number Two

Preserving some of the “country feel” – Widen North Point Prairie Road to
include shoulders, improve the edge drop off, and provide a 10-foot-wide, shared-use path on the east side of the street. See plans here.

Intersection Improvement Concepts

The study reviewed ideas to improve two key intersections along North Point Prairie Road: Bear Creek Drive and the North Point Middle School entrance.

Bear Creek Drive

With the connection of David Hoekel Parkway to Bear Creek Drive, more east-west traffic is expected at the intersection of North Point Prairie Road at Bear Creek Drive. Concepts were drawn up for a standard four-way stop intersection and a small roundabout to illustrate how these approaches would work. Bear Creek intersection concepts.

North Point School Campus

This study suggests that a signal at the North Point Middle School entrance (and possibly one at the high school entrance) would be feasible and may be necessary as the land to the west of North Point Prairie Road develops in the future. Link to school entrance concepts.

Sight Distance Improvements

There are several areas along North Point Prairie Road where the hills and valleys limit how far drivers can see, which can pose a safety risk. This study identified three locations where North Point Prairie would need to be reconstructed to smooth out the hills to allow drivers to see far enough to make safer decisions about stopping and turning. Link to profile improvement plans.

  • North Point Prairie at Pasture View Court
  • North Point Prairie at Copper Falls
  • North Point Prairie at Copper Falls

    Main Street Revitalization Project

    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.
