Connecting Arlington

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.

Pedestrian Bridge Erection for Silver Line Extension

Williams Steel Erection Co., Inc. is assembling and erecting 32 pedestrian bridges for Phase 2 of the Dulles Corridor Metrorail Silver Line Extension project.  The bridges will connect the 5 at-grade stations in the median of the Dulles Toll Road and Dulles  Greenway to the wayside parking areas.  Below are pictures from August 21st and 23rd setting 2 spans at the new Herndon Station.  Check back soon for more updates on this project.

Jacking Existing Roof at 1401 Okie Street

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.

Work has also started on the assembly of the pedestrian bridges that will carry passengers from the wayside areas to the stations.  The bridges will be assembled on the ground in sections that weigh up to 200,000 lbs, then hauled to their final location using our heavy haul rig and set in final position with one of Williams Construction Services’ fleet of cranes with up to 300-Ton capacity.  Check back for future updates as the project goes forward.
