Buses only sign on Columbia Street (SDOT)

On February 22, twelve routes from West Seattle and Burien will begin using the new Columbia Street transit “pathway” to reach Downtown Seattle. These routes (RapidRide C Line, 21X, 37, 55, 56, 57, 113, 120, 121, 122, 123, 125) carry a combined 26,000 daily riders and continue south via Alaskan Way to State Route 99.

In the year since the viaduct was permanently closed, these routes have shifted between two corridors through Pioneer Square and the stadiums, but they will now have a permanent home on the waterfront. A new set of bus stops on Columbia Street to the east of Alaskan Way will be served by all twelve routes, restoring much-needed year-round bus access to the Colman Dock ferry terminal that has been absent for several years.

Changes to lanes on Columbia Street (SDOT)

The pathway has a set of continuous bus lanes in each direction and non-bus lanes for westbound traffic. There will be several points where turning traffic will be forced to merge through the westbound bus lane to reach marked turn lanes, but eastbound bus lane should remain unimpeded. The street has been entirely rebuilt by SDOT with concrete pavement and improved underground utilities to serve the waterfront redevelopment project.

Bus lane painting and other late-stage work began on Monday and is set to be completed within a week depending on the weather. The city plans to open a set of bus-only lanes on Alaskan Way between Columbia Street and South King Street by late 2021, while the waterfront promenade is still scheduled to be finished in 2024.
