The scope of this project is to remove and replace two dilapidated bridges located within the Mt. Si Natural Resources Conservation Area (NRCA). The two replacement bridges are located on the Mt. Si Trail and Francis North accessible/interpretive trail, which are located at the Mt. Si Trailhead. Currently the accessible/interpretive trail is closed to recreational users for public safety purposes due to the unsafe bridge conditions. The Mountains to Sound Greenway Trails Assessment, June 2005, noted that the two bridges on the Mt. Si Trail and the Frances North accessible/interpretive trail loop were in poor condition and in need of replacement. The two bridges were built with natural wood stringers approx. 15 years ago and, because of their age and our Northwest weather conditions, the bridge stringers have become rotten and the bridges are on the verge of collapsing. The Mt. Si NRCA trail system is a popular destination for Puget Sound Metropolitan Area residents. It is about a 30 - 40 minute drive east on I-90 for approx. 52% (i.e. 3.3 million people) of the state's population. If funding is not provided for the bridges, the accessible/interpretive trail will remain closed to public use.
