The ST3 program is widely viewed as disappointing for Kirkland. The city wasn’t quite passed over: I-405 BRT will serve Totem Lake and NE 85th St in 2024, and rail will extend to South Kirkland in 2041. But most observers focus on the missed opportunity to connect Downtown Kirkland via the Eastside Rail Corridor. Why did this happen, and what are the implications?
It’s instructive to start at the beginning. In mid-2015, ST3 was anticipated as a 15-year package including rail to Redmond and BRT on I-405. Other Eastside rail investments would follow in ST4. Recognizing the risks of waiting, Kirkland developed a Bus Rapid Transit proposal with Sound Transit and Metro buses running in largely exclusive right-of-way along the ERC. The reduced capital costs, it was hoped, could fit within a 15-year program.

As a 25-year program came into view, the calculus shifted to potentially include a rail line between Kirkland and Issaquah. But Kirkland’s study highlighted several advantages of a busway. It could serve more destinations including Seattle (with four times the demand of a Bellevue-Kirkland service). It connected more activity centers within Kirkland, and eased the challenge of serving Downtown Kirkland. A busway might better balance trail uses, though not enough to appease South Kirkland neighbors who were determined not to have any transit passing their homes.
Kirkland was convinced of the advantages of BRT on the Corridor, but other stakeholders were less supportive. Sound Transit, improbably, estimated only about as many riders on the BRT in 2040 as the corresponding Metro routes today, emphasizing time penalties of deviating off the corridor to serve denser areas. The tortured history of BRT “alternatives” to rail on the Eastside ensured transit lobby groups would be skeptical. Issaquah worried about the implications of Kirkland BRT for its own rail plans. Even Bellevue placed a greater emphasis on I-405 BRT as a major north-south connection.
