The Edwardsville Town Center is a 25.55-acre multi-use site in Edwardsville at the intersection of IL Route 157 with Governors Parkway. The proposed development at full build-out is anticipated to consist of residential townhouses, retail, restaurants and services. Ingress to and egress from the proposed development is being sought through the construction of two full-access entrances; one entrance along Governors Parkway approximately 1000’ east and one entrance along IL Route 157 approximately 1450’ south of the intersection of IL Route 157 with Governors Parkway / E. University Drive. The proposed development will also use an existing full access entrance along IL Route 157 at University Park Drive/ Mutual Court. In addition to the three full access points, construction of an additional right-in/ right-out access point is proposed along IL Route 157. The project includes restriping Governors Parkway to establish a westbound left-turn lane at proposed entrance, and roadway widening to establish an eastbound right-turn lane at proposed entrance, roadway widening along E. University Drive to establish an eastbound right-turn lane at IL Route 157, and widen IL Route 157 to establish a northbound right-turn lane at the proposed and existing entrances.
Scope of Work:
TWM worked with IDOT and Madison County on behalf of the developer to coordinate access for the multi-use development. TWM completed a traffic impact study for the proposed and existing entrances along IL Route 157 and Governors Parkway. Engineers analyzed the traffic impacts of the proposed development to the adjacent roadways, including the need for the construction of left-turn and right-turn lanes and traffic signals at the entrance locations, as may be warranted to accommodate the traffic generated by the new development. This study also analyzes the operating levels of service of the proposed and existing intersections created by the commercial entrances with adjacent roadways and the existing intersection of IL Route 157 with Governors Parkway. This project was completed and approved in 2016. Since that time, the developer updated the land uses anticipated for the development and an addendum was completed to determine the impact to the adjacent roadways as well as the operating levels of service.
