Cost

$12.6 million

Scope

This project includes the construction of Ramps 2 and 3 to connect eastbound/northbound MO 370 and I-70 with westbound Salt River Road. Ramp 2 will consist of a 14 foot wide concrete ramp extending from eastbound MO 370 to the westbound exit ramp from MO 370/Salt River Road ramp to Spencer Road. An auxiliary lane will be built on MO 370 between the westbound I-70 ramp and Ramp 2. Three new bridges will be constructed with Ramp 2 over Premier Parkway, MO 370, and the MO 370/Salt River Road interchange ramp. Ramp 3 will construct a new westbound exit ramp to Spencer Road. The westbound entrance ramp from Spencer Road to Salt River Road will be widened to accommodate westbound traffic. The project is eligible to receive15% Federal reimbursement funding, 55% MoDOT Cost Share funding, and 24% St. Charles County Road Board reimbursement funding.

Construction is expected to begin in 2025.

Scope

This project will install a right turn lane for northbound Mid Rivers Mall Drive at the Home Depot Plaza signalized intersection. The right turn lane will allow turning traffic to move out of the through lanes, which will reduce congestion and increase safety at the intersection. This project is eligible to receive 80% St. Charles County Road Board reimbursement funding.

Construction Begins

Construction is expected to begin in 2023.

Scope

This project will rebuild a one-mile stretch of Spencer Road south of Willott Road to the City of St. Peters boundary at Thoele Road. This residential road is four decades old and failing. The project will narrow the roadway to calm traffic, install roundabouts in place of three unwarranted stop signs, replace existing sidewalks with ADA-compliant sidewalks, and improve pedestrian safety. This project is eligible to receive 80% Federal reimbursement funding and 16% St. Charles County Road Board reimbursement funding.

Construction Begins

Construction is expected to begin in 2024. A final plan is available to view on our Spencer Road Improvement Project page.

Scope

This project will reduce traffic delays and increase safety at the intersection of Mid Rivers Mall Drive and St. Peters Howell Road by adding extra lanes on Mid Rivers Mall Drive and westbound St. Peters Howell Road. The changes will include:

• Construction of a new right-turn lane on northbound Mid Rivers Mall Drive
• An additional lane on westbound St. Peters Howell to provide separate left-turn, through, and right-turn lanes approaching Mid Rivers Mall Dr. (Currently, drivers trying to turn right are in a lane shared with through traffic)
• Medians near the intersection at both new right-turn lanes (westbound St. Peters Howell and northbound Mid Rivers Mall Drive); The medians help "channelize" traffic to separate them from through lanes
• Sidewalks and traffic signals on the southeast corner of the intersection (near the former Llywelyn's Pub location) will be relocated to accommodate lane changes
• Traffic signal head modifications for westbound and northbound traffic
• Increased vehicle capacity to serve this area as development continues

This project is eligible to receive 80% funding through federal Congestion Mitigation and Air Quality (CMAQ) funding administered through the East-West Gateway Council of Governments and the Missouri Department of Transportation (MoDOT), and 16% reimbursement funding through the St. Charles County Road Board.

Scope

This project will extend the life of the Mexico Road bridge over Dardenne Creek by addressing maintenance needs identified by the bi-annual 2020 MoDOT Bridge Inspection. The project will include updating the existing guardrail, an epoxy polymer bridge deck overlay to preserve the deck, and replacement of the concrete bridge approach slabs. The existing concrete sidewalk will be replaced with an Americans with Disabilities Act (ADA) compliant sidewalk, and the pedestrian fence will be upgraded. This project is eligible to receive 80% funding through federal Surface Transportation Program (STP) funds administered through the East-West Gateway Council of Governments and the Missouri Department of Transportation (MoDOT).

Scope

This project will rebuild a 3/4-mile stretch of Barkwood Trails Drive east of Jungermann Road to Maple Tree Drive. This residential road was constructed in the 1970's and the 1980's in segments, and was not designed to support the type of traffic it experiences today. The project will provide pavement designed to handle larger traffic volumes and incorporate intersection and roadway design concepts to control speed and improve safety while limiting stops and traffic congestion. Additionally the project will replace the existing 4 feet wide sidewalk with a 6 feet wide Americans with Disabilities Act (ADA) compliant sidewalk. This project is eligible to receive 80% funding through federal Surface Transportation Program (STP) funds administered through the East-West Gateway Council of Governments and the Missouri Department of Transportation (MoDOT).

Scope

This project will include the removal and replacement of damaged concrete pavement, concrete curb and gutter, and concrete sidewalk along Jungs Station Road from Kings Crossing to Country Mill Court. The traffic signal at the intersection of Plum Tree Drive will be reconstructed and upgraded to improve signal efficiency and reliability. ADA improvements will be made throughout the project including curb ramps at intersections, accessible sidewalk, and accessible crosswalks at the signalized intersection. This project is eligible to receive 80% funding through federal Surface Transportation Program (STP) funds administered through the East-West Gateway Council of Governments and the Missouri Department of Transportation (MoDOT).

Scope

This project will design and reconstruct the aging temporary span-wire signal system with a new permanent steel signal system at the intersection of Harvester Road and Queensbrooke Boulevard. The project will include construction of a sidewalk along the east side of Harvester Road from Queensbrooke Boulevard to Sugarwood Drive and provide a pedestrian crossing at the Queensbrooke Boulevard signalized intersection. (The temporary span-wire signal was installed as part of the Page Avenue Extension Phase 2 project and was not intended to be permanent but was kept in place at the completion of the project due to the increased traffic volumes on Harvester Road.) The permanent steel signal system will be designed to accommodate future development to the east of the signalized intersection. This project also will construct a fiber-optic connection from the Harvester/Queensbrooke signal to the City's traffic network so that our Traffic Department can respond more quickly to outages and changes in traffic conditions. This project is eligible to receive 80% funding through federal Congestion Mitigation and Air Quality (CMAQ) funding administered through the East-West Gateway Council of Governments and the Missouri Department of Transportation (MoDOT).
