King County Metro has begun offering an additional 150 trips on more than 50 routes each weekday throughout King County starting Sept. 22, providing passengers with more frequent and less-crowded bus rides, according to the transit agency.

The additional 88,000 hours of annual bus service, which took effect Sept. 22, includes more peak service in Auburn, Renton, and Bellevue, more frequent service into downtown Seattle on popular routes such as the RapidRide E Line and Route 40, and expanded peak-hour service in West Seattle.

Passengers can read details about changes on Metro’s website (kingcounty.gov/depts/transportation/metro). Changes also are included in a red Rider Alert brochure and new red-colored timetables that will be distributed on buses and at customer service locations, Metro officials said.
