If you want your voice heard on the new proposed light rail tunnel that would run via 110th Avenue Northeast in downtown Bellevue, there are some opportunities next week to learn more and tell officials what you think.

The Sound Transit board decided Thursday to add the new tunnel option to environmental studies for East Link, which will connect Bellevue, Mercer Island and Redmond to the Link light rail system. Officials will update the Bellevue City Council Monday about the proposal.

The new tunnel alternative, called C9T, would be shorter and less expensive than other tunnel options projected to cost $500 million more than the street-level downtown alignment Sound Transit endorsed. Sound Transit has asked the city to figure out extra funding by the end of the year.

The board will make a final route decision for East Link next year, with light rail service slated to start in Bellevue in 2020. East Link is expected to have a ridership of about 48,000 daily.

The council study session starts at 6 p.m. at City Hall. (First floor, 450 110th Ave. N.E.) It also will be shown live on Bellevue Television, Channel 21.

Sound Transit is holding additional workshops next week to talk about East Link, with meetings focusing on the route and station in that area. All meetings run from 5-7:30 p.m.
