King County Executive Dow Constantine and Eastside elected officials will meet at Crossroads Shopping Center tomorrow to celebrate the new connection between Bellevue and Redmond via the new RapidRide B Line, which starts service on Saturday.

On Wednesday morning, special RapidRide buses will depart from the city halls at Redmond and Bellevue, carrying a delegation from each city. The two buses will meet in the middle at Crossroads Shopping Center, where Constantine will be waiting.

Scheduled to join Constantine are U.S. Rep. Dave Reichert, King County Council Vice Chair Jane Hague, King County Councilmember Kathy Lambert, Bellevue Mayor Don Davidson, Redmond City Councilmember John Stilin, and Claudia Balducci, the chair of the Puget Sound Regional Council’s Transportation Policy Board.

The event will start at 10:30 a.m. in the west parking lot at Crossroads (in front of Half Price Books) and last about half an hour.
