Construction

Construction began in August 1998. The bridge was designed by Florida-based Figg Engineering Group and built by PCL Civil Constructors Inc., a subsidiary of PCL Constructors Inc. at a cost of US$17.4 million. The bridge design is the same genre as the Natchez Trace Parkway Bridge. The bridge is composed of four double-tapered piers with stone inlay, two conventional abutments, and 100 cast-in-place segments. After review of the bridge design by the construction firm, the segments were changed from 4.5 m to 5 m segments, deleting 35 segments from the critical path of construction. The bridge was completed on May 30, 2001.

The cast-in-place structure consists of of concrete, of reinforcing steel, and of steel cables.

Awards

In 2002, the bridge received an honorable mention in the Federal Highway Administration's Excellence in Highway Design Awards, Category 3A: Major Highway Structures Over $10 Million. The bridge also received an award that year from the Concrete Reinforced Steel Institute, the only 2002 award-winner east of the Mississippi River.

Unique Features

The cast-in-place cantilever box girder bridge design is the only one of its kind in Virginia.

The bridge is hollow. Beneath the riding surface, the box girders are open with a width of and a height which varies from to . Power and communication lines are carried in the hollow concrete box and run the length of the bridge. Manholes in the bridge deck allow researchers to enter the box to monitor testing equipment.

The support structure of the bridge is inlaid with Hokie Stone to blend in with the environment and meld with the architectural stylings of Virginia Tech.
