The Sound Transit Board on Thursday approved a $1.6 billion 2017 budget that provides $1.2 billion in light rail and other system expansions, including work to begin implementing the additional projects that regional voters approved on Nov. 8.

“In 2017 Sound Transit will make significant progress toward delivering infrastructure expansions that will boost our region’s economy while giving commuters a reliable and desirable alternative to the worsening congestion on our roadways.” said Sound Transit Chief Executive Officer Peter Rogoff in a media release. “Work is already underway on some of the new projects that voters approved just last month.”

The 2017 budget emphasizes intensified construction work toward the 2023 opening of the East Link light rail project, including the scheduled January start of mining a short tunnel through downtown Bellevue. Following the 2016 completion of Northgate Link tunnel mining, station construction will get underway in 2017 as progress continues toward the scheduled 2021 opening.

Work on light rail designs will continue as Sound Transit works toward the 2023 opening of light rail to Lynnwood and 2024 openings to Kent, Federal Way and downtown Redmond.

Project funding in the 2017 budget includes initial steps on Sound Transit 3 projects that voters approved on Nov. 8. Work continuing in early 2017 will include development of a Program Implementation Plan spanning both projects approved in 2008 and 2016, which will include a master program schedule and refinements of internal processes as the agency works expand its capacity to complete a 116-mile light rail system. In the spring, the Sound Transit Board will review this plan and consider amendments to the 2017 budget for additional project work for the year.

With Sound Transit ridership now exceeding 150,000 each weekday, the budget also invests $396 million in transit operations. In September 2017 Sound Transit will begin operating two new round trips on the Sounder south line, providing expanded options and capacity for commuters to travel during rush hours.
