Project Purpose

The focus of this study is to continue the evaluation performed during Round 1 of Project Pipeline on the ST04 (522/Front Royal Pike) study, which identified the preferred alternative as a Partial Median U-Turn on U.S. Route 50/17 to improve traffic operations and accommodate future growth, as well as provide safety benefits.  The project also includes enhancements and extensions of pedestrian facilities along the study area.  The study will focus on mitigating right-of-way and limited access concerns with the Federal Highway Administration and affected property owners. The conceptual design and cost estimate will be refined to incorporate changes and value engineering.
