February 2013
- We have developed a design for replacing and rehabilitating aging concrete on northbound I-405 between S.E. 8th Street and SR 520.
- We will select a contracting team in February 2013 to complete design and build the project.
- This contracting team, also known as a design-builder, will also improve the pavement on both directions of SR 518 between I-5 and SeaTac Airport.
- Project documents are available on WSDOT's Ad and Award site.
- Construction will start in late spring 2013 and be complete by fall 2013.
In this project crews will completely replace concrete pavement on all four lanes of northbound I-405 from SE 8th Street to just north of Main Street in Bellevue. Crews will grind the existing pavement across all lanes and replace failing concrete panels on a section of northbound I-405 just south of SE 8th Street and from Main Street to SR 520.
Why is WSDOT
improving northbound I-405 pavement in Bellevue.
The pavement in this section of northbound I-405 is 40 to 50 years old and showing its age. All the telltale signs of failing pavement are on display - cracks and bumps, ruts and what pavement engineers call spalling. Spalling means the pavement is flaking, chipping or crumbling apart. However you might describe it, the pavement is failing faster than maintenance crews can repair it and it's time for a fix that lasts.
The End Result
When construction is done drivers will experience a smoother ride with improved traction. Extending the life of the pavement also frees up WSDOT crews to work on other essential repair and maintenance tasks.
Project Benefits
- Smoother ride with better traction and new striping.
- Extends the lifespan of the existing freeway pavement.
- Reduces the likelihood of emergency closures for pavement repairs and frees up crews to do other work.
What is the project timeline?
- Early 2013 - Select contractor to complete design and build the project.
- Late spring 2013 - Start construction.
- Fall 2013 - Complete project.
