Southbound Interstate 5 - Bus on Shoulder - project overview graphic

In spring 2020, WSDOT and C-Tran will construct a bus lane using the left shoulder of southbound I-5, to help keep people moving between Northeast 99th Street and the I-5 Interstate Bridge, in Vancouver. 

During weekday travel, when travel speeds on southbound I-5 slows down to below 35 mph, authorized transit buses will be able to use the left shoulder on southbound I-5, to bypass traffic delays.

The bus on shoulder lane is reserved for transit buses only, and are not designed to carry large amounts of traffic.
