Project Description Granite Falls Bridge #102 is approximately 1.5 miles northeast of downtown Granite Falls in a rural area of Snohomish County, Washington. The 340-foot long steel arch truss bridge was built in 1934. It carries Mountain Loop Highway (MLH) traffic consisting of residents, workers, school buses, freight and tourists at 90 feet above the South Fork of the Stillaguamish River. (See Attached Vicinity MAPS 1 and 2.) Age. This bridge replacement project is the highest priority in Snohomish County because of the potential failure due to the condition of the bridge and its age of 86 years. Design life of this type of bridge is approximately 75 years. Structurally deficient. Bridge #102 is structurally deficient and functionally obsolete. Critical access. Bridge #102 provides critical access to the Mount Baker-Snoqualmie National Forest (MBSNF). Because this bridge is of strategic importance, and because the only available detour route is approximately 94 miles long and open only in non‐winter seasons, traffic across the river must be maintained. The only alternative route results in lost time, lost value, higher rate of diesel-related emissions and increased safety conflicts. (See Attached Detour MAP 3.) Economic and recreational corridor. This important economic and recreational corridor is vital to the Puget Sound Region. The highway carries a large volume of car and heavy truck traffic and is the only route existing that can transport the region’s quarry products and lumber to Puget Sound area markets. Gravel quarries contribute much of the truck traffic carried on the bridge. Future developments at these quarries are expected to produce an increase in truck traffic. Granite Falls Bridge #102 is also the “Last Mile” connection between the MBSNF to freight corridors State Route 92 and State Route 9; both on the National Highway System (NHS). Purpose and Need Snohomish County has applied for several TIGER/BUILD grants for this Bridge Replacement project. Each time, the applications passed all of the technical reviews and were forwarded to the United States Secretary of Transportation as a “highly recommended” project. Included is a very detailed BCA completed in 2019 which shows a 69 to 1 Benefit Cost Ratio. Granite Falls Bridge #102 Replacement | www.snohomishcountywa.gov/3028 Page 1 Granite Falls Bridge #102 was recommended for replacement in the 2012 Snohomish County Public Works Annual Bridge Report due to the following: Transportation Challenge I – Insufficient in serving current needs This rural bridge was constructed in 1934 to support the timber industry during a time when logs were transported one-by-one on trucks. Although the existing structure is more than 86 years old, it is actually the third version of a bridge to be constructed at this important location. Significantly, each replacement was in response to changing economics; including levels and types of usage that it served. Since the opening of the current structure, design technology has evolved and the bridge no longer meets current design standards. Also, new industries such as aggregate mining, recreational uses, and tourism have emerged to introduce new economic and transportation demands into the region. The vehicle-travelled way is only 20 feet wide. Trucks, or a truck and school bus, need to wait on either end of the bridge for similarly sized vehicles to pass in the opposite direction. Both sidewalks are too narrow to accommodate non-motorized transportation and are not ADA compliant. Additionally, Federal Highways no longer
