The I-5 corridor between the I-205 interchange and Elligsen Road in Wilsonville is a major congestion bottleneck. ODOT is collaborating with South Metro Area Regional Transit (SMART) to support more reliable travel during peak hours by using the highway shoulder for transit vehicles if and when traffic slows below 35 mph. This innovative concept is referred to as Bus on Shoulder.
The new Bus on Shoulder pilot project extends approximately two (2) miles in the north and south bound directions of I-5 between the I-205 interchange and Elligsen Rd. In this corridor, buses may use the shoulder in clearly marked areas when the speed of traffic drops below 35 mph. South Metro Area Regional Transit (SMART) is the only authorized transit provider that will use this corridor at this time. This project is being planned in conjunction with construction work to ensure efficient use of resources.

For People Who Drive
Priority for shoulder use will always be given to emergency vehicles, incident management (e.g,. fender benders or breakdowns) and maintenance activities. If another vehicle is in the shoulder because of an emergency, buses are required to merge back into the regular travel lanes. Motorists shall obey all traffic laws and regulations. Signs and pavement markings are placed along the corridor noting that shoulder use is for authorized transit vehicles only. Signs also warn motorists when buses will be merging back into traffic at the end of the Bus on Shoulder corridor.
