The project was completed in July 2013
I-5 through King County is nearly 50 years old but was only designed to last 30-40 years. More than 250,000 vehicles, of all types, use I-5 each day. These factors combined with Northwest weather have contributed to concrete that is cracked, rutted, and in need of repair.
The following work took place:
- Crews replaced 64 old and broken panels on northbound I-5 between South Military Road and South 260th Street.
- Crews smoothed ruts and potholes along this three mile stretch of northbound I-5 using diamond grinders.
- The same three miles of northbound I-5 were restriped with highly visible contrast striping and new lane buttons were put in place.
- We replaced 13,000 feet of guardrail as well as 14 old signs with new signs that are highly reflective.
This project ensures that I-5 will last longer and need fewer emergency repairs until funding can be secured for future improvements.
New guardrail and reflective signs keep drivers safe.
Smooth concrete and new panels keep drivers safe from cracks and ruts that can contribute to collisions.
Extending the life of I-5 reduces the need for emergency repairs, which are costly to taxpayers and can cause unwanted congestion during rush hour.
