The I-5 Rose Quarter Improvement Project in Portland, Oregon adds auxiliary lanes and shoulders to reduce congestion and improve safety on the main north-south freeway on the west coast and 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 planning and environmental process is expected to complete in mid-to-late 2019.

Cost and Funding
Partial funding for design and construction phases was provided in HB 2017. The legislature authorized $30 million per year, beginning in January 2022, for the Project based on the estimated project cost of approximately $450 to $500 million (in 2017 dollars).
To meet Section 27c requirements of Oregon’s HB2017, the Project will provide a cost-to-complete (CTC) report to the Legislature by February 1, 2020.
This project includes:
- New ramp-to-ramp lanes (also called auxiliary lanes) along I-5 to reduce weaving and merging to improve safety.
- Shoulders along the highway for stalled vehicles to move out of traffic and emergency vehicles to travel to people quickly and safely.
- Covers over the highway where bridges cross over I-5 for highway safety improvements and enhancing connections to surface streets for bikes, pedestrians and vehicles.
- A new overcrossing for all modes connecting N Hancock Street to N Dixon Street to enhance connections and access in the north and northeast neighborhoods.
- Relocating the southbound I-5 on-ramp from NE Wheeler to NE Weidler to reduce crashes caused by short merging and weaving distances.
- A new bicycle and pedestrian overcrossing from NE Clackamas Street to N Ramsay Way to improve connections for people who walk and ride bikes.
- Upgrades to bicycle and pedestrian facilities on the local street network in the vicinity of the Broadway-Weidler interchange to provide a safer and more comfortable travel experience.
