King County Metro will offer free rides on New Year’s Eve between 4 a.m. on Sunday, Dec. 31, and 4 a.m. on Monday, Jan. 1.

In an additional effort to keep impaired drivers off the roads, Metro will add service to its night routes. The Seattle Streetcar will also be free on New Year’s Eve, and Sound Transit will extend Link light rail service between Angle Lake and the University of Washington.

“As we put the finishing touches on 2017, we want you to be able to get out on the town and come home safely,” said King County Executive Dow Constantine in a recent press release. “Whether you are heading to the Seattle Center or other King County destinations on New Year’s Eve, Metro will get you there and back, all for free. It’s our way of saying thank you for making Metro the nation’s best transit system, and we look forward to riding with you next year.”

King County Coun-cilmember Dave Upthe-grove proposed the free transit idea.

“We want people to go have a good time and know they can get home safely, affordably and reliably,” he said.

Metro will operate regular Sunday schedules on New Year’s Eve with extra buses as needed on several routes serving destinations such as Seattle Center, Capitol Hill and downtown. New Year’s revelers can take advantage of Metro’s recently expanded Night Owl network, with added service on major routes between 1 a.m. and 5 a.m.

Sound Transit will operate extended Link light rail service with trains running northbound from Angle Lake Station every 30 minutes until 1:30 a.m. Southbound trains from the University of Washington will run until 2 a.m.

The Seattle Streetcar will operate until 1 a.m. on Monday, Jan. 1.

On New Year’s Day, all buses and rail service will operate on Sunday schedules, regular fare will be required on all service.
