Overview
We widened approximately five miles of State Route 20 from two to four lanes between State Route 536 (Memorial Highway) and Interstate 5 in Burlington. In addition, we improved the on- and off-ramps at the SR 20/I-5 interchange.
A median now separate east and westbound traffic, helping prevent head-on collisions. Motorists' visibility is improved, giving them the ability to see farther down the road. Wider shoulders provide room for drivers to pull off the roadway during an emergency and will help reduce run-off-the-road collisions.
 | Improves Safety
Widening and dividing the highway with a median and cable barrier will help reduce collisions. The new traffic signals help increase safety at busy intersections. The improved on- and off-ramps at the I-5 interchange help reduce the risk of collisions.

 | Relieves Congestion
The improved interchange has greater capacity for cars, which helps improve traffic flow. Improved on- and off-ramps will help ease congestion.

 | Protects Environment
Much of this work was completed near sensitive waterways. Storm water treatment facilities were built to treat highway runoff. This work included biofiltration swales, vegetative filter strips, detention ponds, and an underground detention system.

Partnerships & Cooperation
Throughout the planning and design phases and two years of construction, we collected input from local officials, community members, drivers and residents. We also held open houses, attended local meetings and worked with the local media to provide updates.
Section 106 consultation was initiated in May 2004 with the Swinomish, Samish, Upper Skagit, Tulalip, and Kikiallus Tribes.
