Cook Road Corridor Study

The Cook Road corridor is a critical link in Skagit County’s transportation network, providing freight access between I-5 and the City of Sedro-Woolley to the east, and a bypass to the congested SR 20 corridor through Burlington. Cook Road serves important general purpose, freight, industrial, and agricultural transportation needs.


The Cook Road Corridor Study analyzed existing and future transportation impacts in the Cook Road corridor and evaluated both short-term and long-term alternatives to improve operations.


Short-term alternatives included modifying traffic control at the I-5 off-ramps, increasing vehicle storage on the I-5 northbound off-ramp, and increasing capacity on Cook Road. Long-term alternatives had higher costs and would fully grade-separate Cook Road from the BNSF mainline.
