There are many express bus routes that go from Downtown Seattle to other places around the city. I feel like some of these routes are not too necessary, and instead there should be a single frequent express route to that area instead.
The Downtown Seattle Transit Tunnel is expected to be closed to buses in 2019. This means that many buses will have to go on the Downtown streets. Metro has a couple plans, but I came up with some alternatives.
Route 99 is expected to end soon due to construction of the Center City Connector on 1st Ave, so Metro should make use of some of the stops. The Center City Connector construction is only between Stewart and Jackson, so the stops north of Stewart are still available.
Removing Express Routes
SR-520 routes (other than one or two peak expresses) will instead run north to the University of Washington station at Husky Stadium, laying over elsewhere in that area.
Instead of going to Downtown, Route 125 will run like Route 50 between Delridge and Alaska Junction. A peak-only Route 125X will run to Downtown along the current 125 routing.
Route 101 will be discontinued. Routes 148 and 169 will be extended to Rainier Beach via Sunset Blvd, MLK, and Henderson. Routes 148 and 169 will each run at 30-minute frequency all 7 days a week, providing combined 15-minute service on MLK between Rainier Beach and Renton. Route 102 will still serve Downtown, possibly with some additional peak trips.
When Northgate Link opens, Route 41 will run only between Northgate and Lake City.
Routes that will no longer have through-routes: 1, 5, 24, 26, 28, 33, 124, 131, 132. Check the section on New Downtown Terminals to see where they would terminate in Downtown.
Routes that will receive through-routes: 40, 70 (see Other Changes section)
Route 2S will always through-route with Route 13. Route 1 will be extended to replace Route 2N on 6th Ave W, terminating at the former Route 4 loop in East Queen Anne.
New Downtown Terminals
Routes Coming from South
Instead of terminating in South Lake Union, RapidRide C will terminate at the current 99 stop at Elliot/Broad, using Broad and Cedar to travel between 1st and 3rd avenues.
Instead of going to International District via Jackson, Route 106 will run to South Lake Union via Boren and Fairview, terminating at the old RapidRide C layover spot.
Route 124 will layover at the current northbound 99 stop at 1st/Cedar, using Wall and Cedar to travel between 1st and 3rd avenues.
Route 150 will layover at the current northbound 99 stop at 1st/Lenora, using Lenora and Blanchard to travel between 1st and 3rd avenues.
Route 120 will layover at the current southbound 99 stop at 1st/Lenora, using Lenora and Virginia to travel between 1st and 3rd avenues.
Routes 131 and 132 will layover at the current southbound 99 stop at 1st/Wall, using Cedar and Battery to travel between 1st and 3rd avenues.
Route 550 will run like Route 554 in Downtown.
Route 102 will run like Route 190 in Downtown.
Routes Coming from North
Route 5 will terminate at the current 70 layover spot at Main St.
Route 62 will stay on 3rd Ave until Jackson, then go on Jackson and terminate at the 99 layover spot on 8th/King.
Routes 24, 26, 28, and 33 will go to Ryerson Base.
Since Route 14 will be through-routed with Route 70 (see Other Changes section), Route 1 will run to Atlantic Base with a few stops along Airport Way.
Route 41 will run like Route 522 in Downtown.
Route 74 will run like Route 76 in Downtown.
Routes 11, 120, 124, and 150 will run at 15-minute frequency all 7 days a week.
Route 47 will run at 15-minute frequency during peak hours, and 30-minute frequency at all other times.
Route 4 will run peak-only between Downtown and Mt Baker TC, operating as an express along Jefferson. It will no longer be a trolley route. Route 3 will run at 15-minute frequency all 7 days a week.
Routes 26 and 28 will no longer be coordinated to provide 15-minute service on Aurora. Aurora already has frequent service with the E Line and Route 5.
Route 27 will move to Jackson between Downtown and 31st Ave S, and it will be renumbered 25. The current route 27 will remain as a peak-only route. Route 14 (and Route 70) will temporarily become diesel routes while wire is placed to Leschi so that Route 25 can be electrified. Routes 14 and 25 will each run at 30-minute frequency, providing 15-minute frequency along Jackson. They will be through-routed with Route 70. Pretty soon, Route 48 will be a trolley route, so the vehicles currently assigned to Routes 14 and 70 will be used on Route 48. After the Leschi wire is completed and Metro receives more vehicles, Routes 14, 25, and 70 will be electrified again.
RapidRide D and Route 40 will swap routings north of NW 85th St. This means RapidRide D will terminate at Northgate TC, and Route 40 will terminate at Carkeek Park. Route 40 will be through-routed with Route 21.
Route 49 will run via Madison/Marion instead of Pike/Pine. Route 12 will run during peak periods only, and Route 60 will be extended to Interlaken Park to replace Route 12 along 19th. I know people might say this 49 rerouting would be redundant to the future Madison BRT, but I think by the time Madison BRT opens, Routes 49 and 36 will be combined into one route running through First Hill.
