Title:

Fall Hill Ave. Widening & Mary Washington Blvd Extension

Location:

Fredericksburg, Virginia

Owner:

The Commonwealth of Virginia Department of Transportation

Client:

Corman Construction, Inc.

Project Start Date:

June 2015

Project Completion Date:

October 2016

Project Overview:

Provided MSE Wall design and materials, select backfill, labor, equipment, supervision and incidentals to build two MSE abutments with wire faced MSE temporary walls, and one stand alone MSE wall. Terra Constructs also provided design, supply of precast coping and C.I.P coping.

Purpose/Challenges:

The existing two lane overpass of Fall Hill Avenue over I-95 needed to be widened to four lanes. MSE abutments, constructed in two phases were needed to complete this work. The first phase consisted of constructing a new two lane bridge with MSE abutments just south of the existing two lane bridge. Once completed, the existing bridge was demolished to make way for the second half of the new bridge, also supported by two new MSE abutments.

Solutions:

To enable the new bridge to be constructed in two phases, a temporary wire faced MSE wire wall was required to be built perpendicular to the face of each abutment at the center line of the new bridge structure.

Outcome:

Terra completed the project within the awarded performance period.
