Scope Of Work

Description:            

This project was designed to improve traffic flow by extending Glenn Drive to Cedar Green Road and eliminating the exit from Route 28 to Cedar Green Road. It has further converted Route 28 to a limited-access highway and has provided a four-lane connection between Davis Drive and Cedar Green Road. Construction was administered by VDOT under the Route 28 PPTA contract and is being maintained by VDOT post-completion. Road design meets VDOT criteria and right-of-way was acquired for the full four-lane typical section.  Glenn Drive was extended north to Cedar Green Road and a new four-lane road was also extended east to Davis Drive. The east-west portion of old Cedar Green Road was widened to four lanes similar to Glenn Drive and is now called Belfort Park Drive.  The project also includes sidewalks along the north side of Cedar Green, from Shaw Road to Davis Drive. As development along Glenn Drive and the south side of Cedar Green Road progresses, additional pedestrian facilities will be provided by adjacent developers.  Minor improvements to Shaw Road have also occurred, including a new southbound auxiliary lane with connection to Cedar Green to the west, and extending the northbound turn lane on Shaw Road approximately 125 feet to the intersection with Cedar Green.
