Under Construction: Route 311 and Route 419 Roundabout - Roanoke County

Public outreach ►

The primary purpose of this project is improve safety and traffic flow at the intersection of Route 311 and Route 419 in Roanoke County at Hanging Rock by replacing the signalized intersection with a roundabout.

As of 2016, approximately 14,000 vehicles use this intersection each day with significant congestion occurring during peak travel times. Constructing a roundabout can enhance safety, improve traffic flow and cost less to build and maintain when compared to traditional intersections.

In addition to the roundabout, the project also includes adding paved shoulders for bicycle use and constructing pedestrians crosswalks to connect to the Hanging Rock Battlefield Trail.

Work is expected to start in late April and be completed in late fall 2022.  During construction of the new roundabout, drivers can expect the following impacts:

From late April through Memorial Day

Nighttime lane closures with flaggers controlling traffic may be in place between 9 p.m. and 6 a.m., Sunday through Thursday, at the intersection of Route 311 and Route 419 starting in late April for pipe installation and for paving to construct a new right turn lane and a portion of the new roundabout. 

Early June through early August: Closure & Detour

Portions of the Route 419 and Route 311 intersection will be closed, and a detour will be in place for approximately four to six weeks sometime between early June and mid-August.

During this time period, some drivers will need to detour around the partial intersection closure onto Interstate 81 using exit 140 onto Thompson Memorial Drive and exit 141 onto Route 419.

For four to six weeks, drivers will not be able to turn left from northbound Thompson Memorial Drive onto Route 311. In addition, northbound Route 419 traffic will not be able to continue straight at the intersection onto Thompson Memorial Drive. Southbound Thompson Memorial Drive traffic will not be able drive straight onto Route 419.

This graphic depicts the traffic pattern that will be in place at the Route 419 and Route 311 intersection for four to six weeks sometime between early June and mid-August.

August through November

The new roundabout is expected to be open to traffic in August or September 2022.  Drivers should still expect nighttime lane closures with flaggers between 9 p.m. and 6 a.m., Sunday through Thursday around the roundabout for final paving, pavement marking and sign installation.

VDOT awarded the $2.4 million contract to contractor E.C. Pace from Roanoke in February.  

Benefits 

This project proposes to construct a roundabout that will enhance safety, improve traffic flow and cost less to build and maintain. The project will also improve and resurface the nearby park and ride lot, add paved shoulders for bicycle use and pedestrians crosswalks to connect to the Hanging Rock Battlefield Trail.
