CONSTRUCTION: Parts of SR 509 will be closed this weekend for paving work


Print This Post  Email This Post

The left lanes of both northbound and southbound SR 509 in Burien will be closed this weekend – from Aug. 11-14 – for paving and guardrail replacement.

Lanes will close at 7 p.m. Friday, and reopen at 6 a.m. Monday.

The paving work is weather-dependent, and work will take place between S. 168th Street to S. 112th Street:

Why is WSDOT repaving northbound SR 509?
Also known as the Burien Freeway, the northbound lanes were last paved in 2003 and the pavement is now cracked and rutted from the nearly 28,000 vehicles that use SR 509 between South 168th Street and South 112th Street in Burien each day. Contractor crews are grinding down the top layer of pavement and repaving it with asphalt, creating a smoother and safer surface.

Along with repaving northbound SR 509, crews are replacing four pedestrian curb ramps at the corner of South 128th Street to make it easier for everyone to cross the street.

Why is WSDOT replacing guardrail with concrete barrier?
Two sections of guardrail along the median will be replaced with concrete barrier in order to improve safety and cut back on the time lanes are closed when crews repair damaged guardrail. Maintenance crews can quickly push the concrete barrier into place after a collision, instead of requiring lengthy lane closures to repair guardrail and posts.

The End Result
Drivers will have smoother pavement and maintenance crews will be able to reposition the new concrete barrier quickly after a collision.

Project Benefits

  • Safety – Repaving this section of SR 509 will eliminate cracks, ruts and potholes where water can pool and reduce traction.
  • Economic – Replacing the guardrail with concrete barrier saves maintenance crews time and taxpayer money. Crews can push barrier back in place, but repairing guardrail requires more time and longer lane closures.

What is the project timeline?

  • February 2017: Project advertised for competitive bidding.
  • April 2017: Project awarded.
  • June 2017: Construction begins.
  • Fall 2017: Project is scheduled to be complete.

ALSO: Northbound I-5 in SeaTac, Tukwila
The weekend of Aug. 11-14, three lanes will close to pave the final layer of asphalt on northbound I-5 from SR 516 in SeaTac to South 170th Street in Tukwila. The weekends of Aug. 18-21 and 25-28, three lanes will close for expansion joint replacement at the Duwamish River Bridge in Tukwila.

  • Lane closures will begin at 8 p.m. each Friday. By 10 p.m., northbound I-5 will reduce to two lanes until 5 a.m. each Monday. All work is weather-dependent.
  • The final two weekends of lane reductions, to replace expansion joints at Interurban Avenue, have yet to be scheduled.

Plan ahead
Each day more than 100,000 vehicles travel northbound I-5 between Kent and Tukwila, and up to 30,000 use SR 509 in Burien. During the weekend-long lane reductions, drivers can help ease congestion by:

  • Using bus or light rail service.
  • Carpooling.
  • Scheduling trips early or late in the day.
  • Using alternative routes like I-405, or state routes 99 and 167.

    I guess with the planned weather and the rain of .02 , they rescheduled. The weather was not bad. So when will they complete this project? It seems they work a few hours here or there. They need to pick a section and get it complete. I noticed the repainted the line along the center wall . WHY , if they plan on taking out the center and replace with cement barriers. Now they are going to destroy the work they just did. Maybe the painters were planned before the wall, or there schedule did not get updated. So rework will occur. More Tax Payer $$$
