Two park & rides on the Eastside will close in early 2017 for East Link construction. The South Bellevue P&R, with current capacity of 519 cars, is expected to close later in the first quarter. It will reopen in five years with an expanded capacity of 1,500 cars in a five-level garage. In the second quarter, the smaller Overlake Transit Center P&R will close for up to six years so it can be used for staging materials. Capacity at Overlake is about 220 cars. The future Redmond Technology Center Station will include a 320-stall parking garage.
Closure dates are dependent on construction scheduling and will be announced 60 days in advance. As the dates are confirmed, a more extensive public outreach effort will educate riders about alternatives.
To serve users during the closures, Sound Transit has expanded two existing leased lots and leased space at five new locations, accommodating 350 cars in total. All of the added capacity is at churches in Bellevue excepting one Renton location. The leased lots opened in December. That is less than a 1:1 replacement, but there is also unused capacity at some other Eastside locations such as South Sammamish, Houghton, Newport Hills, and Tibbetts Valley in Issaquah.
Buses will continue to serve South Bellevue during the closure. These include ST 550, 555 and 556, and Metro 241 and 249. The southbound stops will be relocated across the street. Road capacity will be reduced during some of the construction, but a reversible lane ensures two lanes can remain open in the peak direction throughout.
The closure of the P&R at Overlake Transit Center is being mitigated in part with ST Express service to nearby Overlake Village on ST 541, launched earlier in 2016. Sound Transit Express service on the SR 520 and I-90 corridors was increased in 2016, improving the frequency of service at several historically under-utilized lots.
