Project Description

This $46.7-million project will replace the signalized intersection at Route 460 and Southgate Drive at the entrance to Virginia Tech with a diverging diamond interchange. This new interchange will eliminate one of the last two at-grade intersections on the Blacksburg Bypass section of U.S. Route 460.

Two new bridges will be constructed over U.S. Route 460 Bypass and portions of Southgate Drive and the Huckleberry Trail will be relocated.

Project Timeline

The project was awarded in March 2015 and construction on the project began in Spring of 2015. 

The anticipated construction duration is 56-57 months. Access to all properties will be maintained during construction.

On October 1, 2016, the new roundabout opened to traffic on Southgate Drive at Duck Pond.

The project is expected to be open to traffic in December 2018 with incidental work to be completed by December 2019.

Traffic Impacts

While temporary road and trail detours may be necessary for short durations, impacts to users of these facilities should be minimal. 

Access to all properties will be maintained during construction.

CURRENT CONDITIONS

Lane and road closures and activity in the work zone continue. Motorists should use caution in the area and expect delays.

Discovery Drive in Blacksburg will be closed for use as a storage, staging area and access point for the Southgate project. Discovery Drive is a dead end cul-de-sac in the Corporate Research Center area and will be closed for the duration of the project.

INNOVATION DRIVE CLOSURE – Innovation Drive will be closed at the intersection of existing Discovery Drive in Blacksburg the week of April 24 for construction at the intersection of Discovery Drive. This road closure will extend through June 24.  Traffic will have access to the businesses on Innovation Drive from either end of Innovation Drive off of existing Research Center Drive.

HUCKLEBERRY TRAIL SHIFT - Work on the Underpass under Route 460 began on Monday, November 21, and will extend through several months until completion. Flagging operations and shifting of the trail within the construction area will occur at various times throughout the construction timeframe. Impacts to pedestrian and bicycle traffic will occur. Caution is encouraged for everyone utilizing the Trail to be alert as heavy equipment will be operating in the area.

Drive It! Video Simulations of Southgate Connector Project

These videos provide a virtual drive though on future sections of the Route 460 Southgate Connector project in Blacksburg. The video provides a rendering of what the completed road will look like. The primary purpose of this project is to improve safety and reduce congestion by replacing the existing signalized intersection at Route 460 and Southgate Drive at the entrance to Virginia Tech with a new interchange. This interchange project will include the relocation of portions of Southgate Drive and construction of roundabouts at its intersections with Duck Pond Drive and Research Center Drive.

Environmental Assessment

In July 2013, the Commonwealth Transportation Board approved the location for the project.

Following the CTB’s approval, the Virginia Department of Transportation (VDOT) revised the environmental assessment for the project and sent the revised document to the Federal Highway Administration (FHWA). VDOT worked with FHWA to finalize the environmental study.
