SR 303 Adaptive Signals (Sheridan to Riddell)

Project Purpose

The SR 303 corridor is a multi-modal network of local roads, sidewalks, bicycle paths, bus routes, and other facilities that balance mobility and critical access for residents throughout Kitsap County as well as City of Bremerton residents by connecting a variety of diverse residential and commercial neighborhoods. The City seeks to improve SR 303 corridor reliability, travel times, and safety through an initial implementation of Adaptive Signal Control Technology (ASCT) at five existing signalized intersections including:

1. 1. Sheridan Road
   2. Sylvan Way
   3. E Broad Street
   4. Hollis Street
   5. NE Riddell Road

Noted as an early improvement priority in the SR 303 Corridor Plan, ASCT can be implemented cost-effectively into existing signal systems and utilize real-time traffic monitoring to optimize traffic signal timing. In addition, incorporating this technology along the SR 303 corridor provides future opportunities to implement Transit Signal Priority (TSP) systems. A high-level overview of ASCT is available on the FHWA Center for Accelerating Innovation.

Project Status

In May 2024, the City executed a preliminary engineering design contract with Transpo Group Inc. The consultant completed the work for the initial contract which informed the remaining needs of the design phase. As an expected result, the City executed a contract supplement with Transpo Group Inc in November 2024 for the amount of $429,694.06, resulting in the overall design contract amount of $529,170.52.

The 60% design milestone was completed in September 2025 and the City reviewed and returned comments in October 2025.  In January 2026, the City completed a Request for Proposal competitive process to identify the ASCT vendor to be used for the project and Econolite Systems was found to be the most qualified firm. The next steps will be to finalize the design and advertise the project for construction in the summer of 2026.

Project Funding 

The project was selected for funding through the Kitsap Regional Coordinating Council (KRCC) 2022 Countywide Competition Process. The funding award is through Puget Sound Regional Council (PSRC) and the planned improvements under this project are part of the Regional Transportation Improvement Program (TIP) for 2023-2026. The grant includes $2,068,230 in FHWA funds for the preliminary engineering (PE) and construction (CN) phases. A local funding match of $451,770 is required as a condition of the grant which is included in the Transportation Capital budget. The overall project cost is estimated at approximately $2,520,000.
