23rd Avenue S Reroutes
Routes 4 and 48 will detour for a year
This spring, both routes will move from 23rd Avenue S to Martin Luther King Jr. Way S between S Jackson Street and Rainier Avenue S (see map). The detour will last about one year, while the Seattle Department of Transportation makes improvements to increase safety and mobility along 23rd Avenue S.
Both routes will have the same level of service during the detour as they do today. This means buses will come as often as they do today, during the same hours of the day.
- Since there is no trolley wire on Martin Luther King Jr. Way S, all service south of E Jefferson Street will use diesel buses beginning on Saturday, March 10. On weekdays, continuing Route 4 riders will need to transfer between the regular electric trolley bus and the diesel bus shuttle at E Jefferson Street. On weekends, diesel buses will serve all of Route 4 so there will be no need to transfer at E Jefferson Street.
Both the weekend service and the weekday shuttle service will use full-sized, accessible Metro buses that run on diesel fuel.
- When construction begins along 23rd Avenue S, Route 4 buses will move to Martin Luther King Jr. Way S. After this move, the detoured shuttle will no longer serve 23rd Avenue S and Judkins Park (between S Dearborn Street and S Judkins Street).
- Route 48 will serve 23rd Avenue S until construction requires buses to move to Martin Luther King Jr. Way S.
Seattle will begin construction this spring to improve safety and mobility along 23rd Avenue S between S Jackson Street and Rainier Avenue S. Work will include street repaving, utility upgrades, sidewalk improvements, and more.
