This bridge was built in 1915 by the Toledo Bridge and Crane Company and the Weymouth Construction Company. It was originally located across the Nooksack River on Guide Meridian Road, current WA 539, south of Lynden. In 1951 the steel through-truss was moved to its present location across the Middle Fork Nooksack River, when a modern structure replaced it on Guide Meridian Road. When relocated two truss panels where removed, reducing the 380-foot bridge span to its present 338 feet. Nonetheless, the bridge remains the longest pin-connected highway bridge in Washington State. In 2007 Whatcom County replaced the deck and approaches and painted the bridge.
