SR 20 - North Cascades Highway

State Route 20 is the northernmost route across the Cascade Mountain Range in Washington and is commonly referred to as the North Cascades Highway. This scenic byway offers travelers a wide array of beautiful vistas and is part of the Cascade Loop , a 400-mile driving tour through the Cascades.
Washington State was one of the first states in the country to establish a system of scenic highways. Scenic highways pass through the varied terrain of Washington reflecting the depth of its scenic, cultural and historic landscapes.
Bus shoulder lanes are authorized bus-only lanes that run along selected freeways. They are a low-cost solution that fully use the capacity of existing corridors and provide immediate benefits to fixed route buses operated by local transit agencies.
In the growing Puget Sound region, WSDOT is opening peak-use shoulder lanes in strategic areas. This construction approach allows us to add more space for travelers in a quicker and more cost-effective way than expanding highways.
