41st Street Overcrossing

HWA performed a geotechnical investigation for the design and construction of a 0.5 mile extension of 41st Street, extending from I-5 over the BNSF right-of-way and onto the old Everett Landfill site. The new roadway included a single-span bridge over Smith Avenue and a large 3-span bridge over the Burlington Northern Santa Fe (BNSF) raildroad as well as 8 mechanically stabilized earth (MSE) fill walls up to 30 feet tall.
