SR 509 - SB S 160th St Vic to S 112th St Vic - Paving and ADA Compliance - Complete May 2015

In the spring of 2015, contractor crews working for WSDOT repaved southbound SR 509 from South 112th Street to Southwest 160th Street in Burien.

This four-mile stretch of highway, popularly known as the "Burien Freeway," was failing. Large cracks formed in the pavement and many areas were uneven as the result of potholes and previous maintenance repairs.

Contractors also upgraded two pedestrian ramps at Southwest 128th Street to provide a safer transition for users.


How you benefit

Improves safety
Repaving this section of SR 509 removed cracks, bumps and an uneven surface.

This creates a smoother surface for drivers and eliminates areas where water can pool and ice can form.

The upgraded pedestrian ramps at the bottom of the SR 509 exit to Southwest 128th Street also provides a safer transition for users to cross at the ramp intersection. 

Economic incentive
Repaving the highway with new asphalt extends the life of SR 509 and reduces annual maintenance costs.


Partnerships & cooperation
WSDOT worked with the City of Burien and Sea-Tac Airport to gather input on our repaving and traffic control plans to reduce the work impact on the 27,000 vehicles that use this stretch of highway every day. 


Pre-Existing Funds (PEF): $1,721,000
Total: $1,721,000
