Sullivan Road / Trent Avenue Interchange

The city is planning to reconstruct the existing interchange at Sullivan Road and Trent Avenue (SR 290). This project replaces both Sullivan Road bridges over the BNSF Railway tracks and four lanes of Trent. The existing signalized intersections will be replaced with a "peanut" roundabout. The project seeks to improve mobility and safety for all users: vehicles, pedestrians and bicyclists. A shared-use path will be added along Sullivan's west side and a new, wider sidewalk will be built on the east side.

The city evaluated four potential new interchange configurations in fall 2022. The city's process included collaboration with the Washington State Department of Transportation (WSDOT), BNSF Railway, regional stakeholders, neighboring industries, and the general public. In December 2022, city council passed a motion selecting Alternative 2 - Diamond Interchange with Peanut Roundabouts as the selected, preferred alternative.

RAISE FY24 Funding Request

The project's estimated total cost is $42.3 million. In February 2024, the city submitted a grant application for $25 million (PDF) to the USDOT's Rebuilding American Infrastructure with Sustainability and Equity (RAISE) discretionary grant program. The city also submitted various funding requests to WSDOT, the Washington state legislature and the U.S. Congress. Funding programs will announce their awards likely by fall or winter 2024.

The city has secured approximately $7.6 million of federal and local funds to deliver the engineering and right-of-way phases of the project. The city is now pursuing construction phase funding. A funding breakdown of the overall project (as of March 2023) is provided:
