This bridge was originally built on the Guide Meridian Road over the Nooksack River. In its original location, this bridge had a span of 380 feet. In 1951, the bridge was replaced with a larger bridge, and the old bridge was relocated here to Mosquito Lake Road where it was shortened by two panels, making its span 338 feet. The photo to the right shows the bridge in its original location. The Weymouth Construction Company was the original contractor for the bridge and the Toledo Bridge and Crane Company fabricated the truss.
Despite being shortened, the bridge's length of 338 feet remains an impressive example of a pin-connected truss span, and indeed it is the longest pin-connected highway truss span in Washington State. It also is, in general, an early and rare pin-connected highway truss, since Washington State does not have many bridges from these periods of construction remaining.
The bridge is an unusual example of a Pennsylvania truss bridge; technically it is a hybrid of a Parker and Pennsylvania truss, since the end panels are not subdivided. Traditional Pennsylvania truss bridges have subdivision of all panels.
In its current location, this bridge also includes a couple non-original box beam approach spans. It seems ironic that the bridge was shortened only to have approach spans added. Could the approach spans not have been avoided by leaving the bridge its original length?
The truss bridge is today in good physical condition.
