Should we address the traffic issues at the Columbia Blvd. ramps in Oregon?

Description

Provide southbound off ramp and northbound on ramp between Columbia Boulevard and I-5 to improve truck freight access to Columbia Corridor and reduce truck traffic in North Portland neighborhoods.

Transportation Performance

Reduces truck traffic on Interstate and Denver (south of Argyle) by over 70% during peak periods. Reduces total traffic on Interstate and Denver (south of Argyle) by approximately 40% during peak periods. Increases truck and total traffic on Columbia Boulevard by 500-600 vehicles per hour west of I-5 (a 30 to 50 % increase over Baseline). During the morning peak, reduces total traffic on the Marine Drive northbound on ramp to I-5 by over 30%, and reduces truck traffic by approximately 20%, thus improving operations at a highly congested interchange. Requires modifications to the Delta Park/Victory interchange, including signalization of northbound and southbound ramp intersections.

Displacements

As currently conceived there are no displacements.

Cost

Construction Cost (2001 $): $70 million
