The project objectives are to address safety, congestion, capacity preservation, and bicycle/pedestrian access concerns along the Route 220 / 220 Alt (Roanoke Rd / Cloverdale Rd) corridor. One node and one segment were identified as VTrans Priority 1 needs along the study corridor, with 4 additional segments identified as Priority 2 needs. Goals are to identify safety and operational improvements to reduce congestion and improve safety and access for all transportation users.
