Interstate 5 (I-5) is the main Interstate Highway on the West Coast of the of the contiguous U.S. from Mexico to Canada. Running parallel to the Pacific coast states of California, Oregon, and Washington, it serves several large cities on the U.S. West Coast, including San Diego, Los Angeles, Sacramento, Portland, and Seattle.

In Portland, the I-5 Rose Quarter Improvement Project will add auxiliary lanes and shoulders to reduce congestion and improve safety on I-5, the main north-south freeway on the west coast. It also redesigns the multimodal local street network.

The project will smooth traffic flow on I-5 between I-84 and I-405 where three interstates intersect and feature the biggest traffic bottleneck in Oregon. The project will also improve community connections by redesigning overpasses and reconnecting neighborhood streets, enhancing public spaces, and promoting economic development opportunities.

The project’s transportation improvements allow the City to implement the development goals for the N/NE area and realize the City’s Central City 2035 Plan.

The project is located in the Portland Metro Area on Interstate 5.
