SR 525 Walkway
Location: Mukilteo, WA
Officials with the City of Mukilteo knew that widening SR 525 would also require sidewalk upgrades, a particularly challenging prospect for a 0.33-mile stretch sandwiched between a developed hillside and unstable, steep ravines. Otak was hired to survey the project area, analyze design alternatives, complete design and construction documents and provide construction observation and administration services. The firm also managed inspection for 1,800-linear-feet of a multi-use sidewalk, two precast double-tee bridges, storm drain piping and detention facilities.
