Voters have passed a $54 billion proposal that will expand mass transit across King, Pierce and Snohomish counties over the next 25 years.
As of 11 p.m., early numbers had the ballot measure known as Sound Transit 3 winning 55 percent to 45 percent. It's enjoying large support in King County, with 59 percent voting in favor and 41 percent voting against. In Snohomish County, it was winning by a slimmer margin of 52 percent to 48 percent.
Pierce County voters are rejecting the measure, though. The vote there was 56 percent against, and 44 percent in favor.
Supporters of the measure said they are optimistic that late voting returns will come up in the proposition's favor.
King County Executive and Sound Transit Board Chair Dow Constantine said he is excited to begin working on the massive project.
"I am so happy that the people understood how important this was," he said. "I cannot overstate the importance of this vote in the future of this region."
Sound Transit 3 would expand light rail to Everett, Tacoma, Redmond, Issaquah, West Seattle and Ballard. It also would add service to the Sounder commuter rail and to bus rapid transit in the region.
The measure comes with a tax increase for residents in the three counties. Car tab taxes would go up to $110 per $10,000 of vehicle value. There would be a sales tax of 1.4 percent. And new property taxes would be added -- $25 for every $100,000 of home value. Commercial property owners would pay that, too.
