Tacoma residents and those who frequent South 21st Street should be aware of disruptions as the road will be closed for six to eight weeks starting tomorrow. The closure is due to the Prairie Line Trail Project, which aims to connect the waterfront to downtown Tacoma through a network of trails for non-motorized transit. According to a statement from city officials, the project will complete an important segment of the local and regional trail network, as per KIRO 7.

The project includes significant infrastructure work such as sewer improvements, paving restoration, and the completion of road construction. The I-705 and State Route 509 interchange near Pacific Avenue will remain open, and drivers are advised to follow detour signs around the closed segment. In addition to the trail project, other closures will occur from yesterday until Friday due to maintenance work by city personnel, which will also involve graffiti removal and vegetation management, The News Tribune reported.

As city public works staff manage the detours, local motorists and commuters should expect modified traffic routes. Officials have stated that these temporary disruptions are part of a broader plan focused on future urban planning and transportation. South 21st Street will undergo changes, with the Prairie Line Trail contributing to the development of a more accessible urban environment.
