Granite Falls Bridge 102 is the gateway to an important economic and recreational corridor. It spans the Stillaguamish River approximately 1.5 miles northeast of downtown Granite Falls, and is part of the 52-mile Mountain Loop Scenic Byway between Granite Falls and Darrington.
The bridge and corridor provides access to homes, vacation properties, sand and gravel quarries and logging operations as well as many square miles of hiking, camping, and other outdoor recreation activities. The Granite Falls Bridge is part of a larger program to increase freight mobility and capacity through the area.
Phase I: Granite Falls Alternate Route or Quarry Road
On November 19, 2010, a 1.9-mile truck route that diverts freight traffic around downtown Granite Falls was completed. The new alternative route has three roundabouts in contrast to three stop signs and one traffic signal on the old route. Truckers save time and gas on this new route, reduce engine emissions and experience a smoother ride, while Granite Falls residents and visitors now enjoy a safer, and pedestrian-friendlier, downtown.
Phase II: Bridge Replacement
The current bridge is a two-lane, 340-foot long, structure built in 1934. Snohomish County Public Works is planning to replace the bridge when construction funds become available. The project is currently at 30% design, with 100% design anticipated by August 2017.
The proposed plan is to construct a new bridge just west (on the downstream side) of the existing bridge. The current bridge will remain in place to provide for traffic corridor needs throughout the new construction. The proposed bridge replacement is planned as a three span, precast, concrete girder bridge; the bridge will have two 15-foot lanes and two sidewalks.
The new bridge will be wider and longer than the existing bridge and will meet current bridge standards and provide increased traffic capacity.
