A CID2 Link Station is Important
In Every City NEEDS a Transit Hub", Reece Martin at RMTransit explains how sticking with the originally-planned second CID Link station is a unique opportunity to create the biggest and most-used multimodal transit hub in the Pacific Northwest. It would connect all of Link lines 1, 2, and 3, Sounder, Amtrak Cascades, Greyhound, the First Hill Streetcar, the proposed City Center Connector streetcar extension to Pike Place Market and SLU, the two stadiums, the walkable Chinatown neighborhood, Union Station's hall with potential reactivation uses, King Street Station's hall, and potentially in-station retail.
Alternatives like a North of CID" station at the King County Administration building would both miss this opportunity and make transfers incredibly bad.
The Fourth Avenue Shallower" alternative is a reasonable compromise between the default Fifth Avenue station (which activists in the CID don't want) and a station too far away. It's more expensive, but this is an existential issue for the network. The #1 issue for a multi-line subway network is good transfers between all the lines. Over half of Link's destinations will require a train-to-train transfer. This is key to maximizing ridership, getting the most out of our investment in it, and making the network far more useful.
