Red Bridge 537 is located on the scenic Mountain Loop Hwy in the Mount Baker-Snoqualmie National Forest approximately 18 miles east of Granite Falls. The three-span bridge was built in 1954 and measures 161-feet long and 26-feet wide. It carries two lanes of traffic over the South Fork Stillaguamish River.
The 68-year-old bridge has varying levels of corrosion and deteriorating surface paint. Snohomish County Public Works plans to remove the old paint, perform minor structural repairs, and repaint the structural steel. The bridge will be painted Insignia Red to be consistent with historical records of an earlier railroad bridge, which had rusted red in the 1930s.
Schedule
Work is expected to begin in 2024.
Traffic Impact
During construction, drivers can expect single-lane closures with minimal delays.
Funding
Funding for the $1.9M project comes from the Federal Highways Bridge Program and the Snohomish County Road Fund.
