New bridge rendering over route 460 (provided by)

The Virginia Department of Transportation (VDOT) is building a new, grade-separated interchange to replace the intersection of Southgate Drive and U.S. 460 and relocate Research Center Drive. This will allow for the expansion of the Virginia Tech Montgomery Executive Airport. The 1,000 foot runway and safety zone extension will permit use by larger airplanes and help support the region’s economic development efforts.

The new Research Center Drive will roughly follow an existing farm road. The road will connect Innovation Drive in the Corporate Research Center to a roundabout intersection with the new Southgate Drive at Duckpond Drive via a new on/off ramp bridge being constructed over U.S. 460.

The new interchange and Southgate realignment is expected to be open for traffic by December 14, 2017, based on VDOT's schedule, with the full project completed by December 2018.

Ongoing Construction
(Updated December 2017)

New Interchange (U.S. 460 – Southgate Drive)
Upon completion of the installation of pavement markings, the new Southgate Interchange will be opened to traffic on Thursday, Dec. 14, (time dependent upon drying of pavement marking).  While the new roadways will be open to traffic, construction will continue along portions of the project.

Existing Southgate Drive
The existing section of Southgate Drive between Route 460 and Duck Pond Drive will be closed permanently on Wednesday, Dec. 13.

Existing Research Center Drive

The existing Research Center Drive will be remain open for a short period (likely to close later this winter).

Huckleberry Trail
New sections of the Huckleberry Trail have been opened to traffic and important grade separated trail crossings have been improved.  Several sections of the trail are still under construction and will be opening soon.
