From a Metro service bulletin:
In response to customer input and real time observations, along Fourth Avenue and Pike Street, and to facilitate the improved operation of buses in the downtown Seattle core area.
Starting Monday, November 5, Metro routes 10, 11, 43, 47 and 49, traveling toward Capitol Hill, will no longer serve the stop on Pike Street at 6th Av. They will make their usual stops on Pike St just west of Fourth Avenue, then again just west of Convention Place.
This revision is being made to facilitate the movement of five other routes that will be stopping on Pike St at 6th Av on their way to northbound I-5.
Two late night trips on the Route 84 Night Owl will continue to serve the stop on Pike at 6th.
Metro expects this service revision to help all Pike St routes operate more efficiently and realize improved travel times.
Your patience as we implement these revisions and work to enter the information into our systems
Thanks for riding and for using Metro’s services.
