ST3 candidate projects

From Sound Transit

The conversation over the future of mass transit in our region took a big step forward with the release of detailed studies for all the projects that could be part of a ST3 ballot measure next November.

The studies, presented at a special Sound Transit Board workshop, include cost and ridership estimates for each candidate project. Information was also provided on opportunities for transit-oriented development, integration with other transit agencies and non-motorized access options.

These studies will help the Board and public evaluate the relative merits of each project for its possible inclusion in a draft ST3 system plan. The projects being studied were identified by the Board last summer following broad public involvement. The Board is scheduled to release a draft ST3 package in the first quarter of next year that will be shaped into a final measure for voters.

The measure will be funded in part by new taxes that the Washington State Legislature and governor authorized Sound Transit to propose to regional voters, including sales, car tab and property taxes that within the first 15 years could generate approximately $15 billion. Other funding for ST3 would come from federal grants, bonds, existing taxes, fares and other sources.

The potential funding options under discussion include:

• A 15-year measure that could generate up to $26 billion.
• A 20-year measure that could generate up to $30 billion.
• A 25-year measure that could generate up to $48 billion.

The studies provide a lot of details to dig into. Fortunately, our website soundtransit3.org lets you get up to speed. The site includes an interactive map where you’ll find information about the potential projects. You will also find more information on funding options at our document library.

Current and Funded Services include traffic and transit studies for 145th to SR 522 to the UW Bothell campus.

In 2021 light rail service is scheduled to open to Northgate. By 2023 Sound Transit is on track to extend service further north (through Shoreline) to Lynnwood, south to Kent/Des Moines and east to Redmond’s Overlake area. The extensions are expected to increase overall weekday ridership to more than 350,000 by 2030.
