SEATTLE -- King County Metro Transit is asking the public what kind of bus service they'd like to see in Seattle between 2 a.m. and 5 a.m. A survey is now online.

Metro plans to expand its "Night Owl" bus options next year, mainly as a service to people who work non-traditional shifts, people headed to or from Sea-Tac Airport at all hours, and for the homeless.

Metro currently operates on 40 routes during late night with 20 trips happening after 2 a.m. That includes three routes that loop through Seattle between 2:15 a.m. and 4:30 a.m., according to Metro. The proposal would create all-day routes that serve the same areas.

A new after-hours bus service from Seattle to Sea-Tac Airport is also proposed. It would make Route 124 go all the way to the airport after 1 a.m. Route 124 currently goes as far south as the Tukwila Light Rail Station. Link Light Rail, which goes to the airport, does not operate between 1 a.m. and 5 a.m.

The proposed plan includes hourly service all night on RapidRide lines C, D, and E.

The survey will continue until Oct. 30. It's available in English, Spanish, and Chinese.

The final proposal will be presented to the King County Council later this year and would take effect next September if approved.
