In 2004, the City of Sumner updated their long-term Transportation Plan of 2002. The adopted plan identified specific transportation improvement projects that were needed to support the 2020 land use projections. The identified transportation projects allowed the roadways and intersections within the City to operate at or above the City's adopted level of service standards.

Overall Transportation Goal: Provide an efficient and safe multimodal transportation system to improve mobility for residents, employees, and visitors of Sumner while maintaining the small town quality of life within the City and supporting the economic vitality of the City.

The goal identifies the City’s desire to meet the mobility needs of the people that live, work, or visit Sumner. The goal calls for supporting a range of travel modes: auto and truck vehicles, pedestrian, bicycle, and bus and rail transit. The City wants to maintain its small-town character by minimizing the development of transportation improvements that would increase the ability or desire of regional traffic to travel through the community. The remaining goals and policies

further refine the City’s overall transportation system goal. The transportation system must provide improved access and circulation to support the economic

development of the City. The system should be designed to provide access to the industrial and commercial areas while protecting residential areas from intrusion of traffic.
