The brown street name signs highlight the historic Olmsted boulevards that exist throughout Seattle. Responding to a request from the Friends of Seattle’s Olmsted Parks and Seattle Parks and Recreation, brown signs are used when old signs are replaced on many of Seattle’s Olmsted boulevards. The cross street signs, and other street name signs throughout the city, are being replaced using the standard green style. SDOT is replacing aging street signs through the voter-approved Bridging the Gap levy. We have installed new, larger signs at 3,645 intersections since beginning levy work in 2007.
