Woodrow Wilson Bridge Control Tower

Potomac River, Virginia

The $2.5 billion project was designed by Washington architectural firm, KressCox Associates (now Cox, Graae + Spack).The most architecturally interesting aspect is the bridge’s ship-like operator’s tower, an arresting vertical presence in curved glass that emulates the look of an ocean-going ship’s smoke stacks.
Cricursa Curvados S.A., a world-renowned manufacturer of curved and specialty glass products in Barcelona, Spain, created the multi-panel sections of bent layered glass in a “dot” frit pattern.  IG fabrication and installation of the tower sections was handled by Midwest Curtainwalls Inc., Cleveland, Ohio.
“This project was small, compared with our typical high-rise towers, but it was perhaps the most challenging job we’ve ever done,” said Don Kelly, president of Midwest Curtainwalls. “We field-assembled the IG using Super Spacer® TriSeal™ and raised each assembled panel, weighing over 800 pounds, into place using a unique 12-cup lifting apparatus, which we built especially for this project.”
Kelly continued, “This was our first experience working with Quanex’s structural warm edge spacer, but it won’t be our last. We feel that with flexible Super Spacer TriSeal, you have much better chance of getting a continuous primary seal around the perimeter of the glass on both sides of the spacer, adding significantly greater years of service without worry of seal failure.”
