Williams Steel Erection Co., Inc. has once again won Project of the Year, this time for its work on the Ballston Quarter Pedestrian Walkway in Arlington, VA. This award was won in the Class II category.
The company’s work on this project required problem solving a challenging, high-profile project involving complex steel framing and challenging site conditions. You can read more about this process here.
The awards ceremony, previously scheduled to be held at the 48th Annual SEAA National Convention and Trade Show in Charleston, SC, was cancelled due to COVID-19 restrictions. The project will be featured in SEAA’s Connectortrade magazine later this year.
Williams Steel Erection Co., Inc. has erected yet another pedestrian bridge at the new addition to the Kennedy Center for the Performing Arts.
The 150 ton, 310 ft long bridge was fabricated in large sections and deliverd to the site. It was then partially assembled on the ground and erected in 4 pieces over the weekend of May 10th to 13th.
The trapezoid shaped box girder design of the bridge meant custom assembly jigs and shoring had to be used during the operation to ensure stability. The work required a total road closure of a major arterial roadway in the District.
The bridge, which crosses Rock Creek Parkway next to the Potomac River in downtown Washington, DC, is part of the $250 million “The REACH” expansion of the Kennedy Center. It will officially open in September 2019.

It is great to see lots of interest from the community on the recently erected Ballston Quarter pedestrian bridge completed by Williams Steel Erection Co., Inc. The Williams Steel team is honored to be able to use our expertise to enhance our community and the whole mid-Atlantic region. This post contains some highlights of the operation from around the internet.
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.
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.
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. 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.
Williams Steel Erection Co., Inc. is performing the structural steel erection on Phase 2 of the Dulles Metrorail (Silver Line) project. Steel Erection started this summer and the first station is nearing completion.
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.
