Greenbag Road PIE Study
WVDOH, Morgantown, Monongalia County, WV
This West Virginia Department of Highway’s (WVDOH) Preliminary Investigation and Engineering (PIE) project for Greenbag Road (CR 857) is an approximately 3.5-mile-long minor arterial roadway that provides an east-west connection, linking Don Knotts Boulevard (SR 119) and Earl L Core Road (WV 7) in the City of Morgantown, Monongalia County, West Virginia. The Greenbag Road corridor has long been recognized as a challenging roadway to navigate due to existing geometric deficiencies, significant intersection delay during peak hours, and increased volume of truck traffic and development within the corridor.
Stahl Sheaffer was retained to complete a traffic study and preliminary engineering services for an approximately 1.5-mile segment within the corridor to evaluate the existing operation and potential future intersection improvement alternatives with the ultimate vision of transforming Greenbag Road into a safe, efficient, and attractive multimodal transportation facility. Tasks included 3D LiDAR scanning, traffic data collection and volume projections, capacity and queue analysis, safety analysis, signal and turn lane warrant analyses, storage length analysis, signal timing and coordination analysis, and determination of potential intersection improvements options. Results of the analyses and details of the potential improvement options were summarized in the PIE Study and presented to the WVDOH and the Morgantown Monongalia Metropolitan Planning Organization (MMMPO). Based on the results of the alternatives analysis, two roundabouts were ultimately recommended. Stahl Sheaffer prepared preliminary design plans (60%) for the widening of the corridor and design of the two roundabouts, which were presented at public meetings.
