65th Ave S & Southcenter Blvd Signal Improvements

Beginning in late September 2025, the City of Tukwila will launch a major infrastructure upgrade at the intersection of 65th Avenue South and Southcenter Boulevard. The project is expected to last approximately four months and will improve traffic flow, pedestrian safety, and transit accessibility. During construction, temporary disruptions to traffic and pedestrian access may occur. Please follow posted signage and detours, and allow extra time when traveling through the area. These improvements are part of Tukwila’s ongoing commitment to building safer, more accessible streets for everyone—including transit riders.

Key improvements include:

• A new signalized crosswalk will be added to help pedestrians safely cross the street to reach the bus stop
• The bus stop itself will be upgraded with a concrete boarding area, ADA-accessible ramp, and protective bollards to shield riders from nearby traffic
• Sidewalks and curb ramps will be rebuilt to make walking and rolling easier for everyone
• New traffic signals will help manage vehicle flow and improve safety for all road users
• Signs and lane markings will be updated to clearly guide drivers and pedestrians
• A retaining wall will be built to support the new sidewalk and bus stop area
