Workers are installing a new and improved pedestrian bridge over Wilson Blvd in Ballston this weekend, but that will mean some major road closures.

Another Bridge at Loudoun Gateway

Posted on by

Williams Steel Erection Co., Inc. and Williams Construction Services have done it again with the erection of a pedestrian bridge connecting the new Loudoun Gateway Station on the second phase of the Washington Metro’s Silver Line to a new parking garage being built by Loudoun County to service the station.

This 175 ft long, 100 ton bridge was assembled on the ground in two pieces and set in place using Williams Construction Services 300 Ton capacity truck crane.

To successfully complete this project, Williams Steel drew on their extensive experience building pedestrian bridges on 5 of the stations that make up the second phase of the Silver Line for which they won a 2019 Washington Building Congress Craftsmanship Award. The Loudoun Gateway Station can be seen in the background of the photo above.

The tight placement and size of this bridge provided unique conditions which Williams Steel overcame by building the bridge in two sections utilizing a custom engineered shoring solution to support the bridge during final placement. It is this type of carefully planned operation that Williams Steel Erection and Williams Construction Services specialize in.

Connecting Arlington

Posted on by

The Ballston Quarter pedestrian bridge crossing Wilson Boulevard in Arlington, Virginia has been a community landmark for many years. When the owner decided to replace the bridge they wanted to create an iconic structure that would set it apart and had a daring architectural design prepared. Then they had to build it.

This is where Williams Steel Erection Co., Inc. comes in. The complex shape, large size, and location over a busy street in downtown Arlington are just some of the challenges that had to be overcome to build the structure. To make it happen, Williams Steel used innovative “accelerated bridge construction” methods that it has become known for.

First, the 145 ft long, 100 ton bridge was completely assembled about a quarter of a mile from the final location in Mosaic Park. The bridge was fabricated by Crystal Steel Fabricators in Memphis, Tennessee and shipped to Virginia in large, truck-sized pieces.

Next, the bridge was loaded onto, Williams Steel’s Goldhofer heavy haul trailer pulled by our Oshkosh M1040 prime mover and moved from the park to the final location. This operation involved significant coordination to close streets, move traffic lights and signs, and keep the public safe.

Finally, the bridge was hoisted into place using a 600 Ton capacity crane and set down on the piers.

Building the bridge structure using this method saved weeks to months of road closures on Wilson Boulevard and eliminated many of the safety risks associated with a partially completed structure being built over a road. When done properly by experienced professionals, this type of operation is much safer and simpler than traditional methods of construction over roadways.

The team at Williams Steel Erection Co., Inc. provides the resources and experience to complete this and other projects of similar complexity and standing. We are honored to be able to use these abilities to provide services that enhance our community and communities throughout the mid-Atlantic region.

Williams Steel Erection Co., Inc. specializes in complex and challenging projects and one type of project that definitely fits this description is vertical expansions. Here are some pictures of a recent example of 200 Stovall Street with a view of the Alexandria skyline.

Jacking Existing Roof at 1401 Okie Street

Posted on March 6, 2017 by

Williams Steel Erection Co., Inc. is jacking the existing roof structure of 1401 Okie Street in order to preserve the existing truss system as a historical architecturally exposed element.  A fully engineered plan was developed specifically for this operation.  The 150 ft by 75 ft section being jacked was reinforced to accommodate the loading imposed during the operation.  Custom made support frames were designed and fabricated to transfer the load of the jacks and roof to the ground through the existing building structure.  Below are pictures from the setup prior to jacking and after.
