Residents are invited to an open house Thursday to learn more about the possible expansion of the free Broadway shuttle including enhancing the current bus service or switching it to an electric streetcar.

A grant-funded study on improving the shuttle service is nearing completion and Thursday’s meeting will include a review of the findings for how either an electric streetcar on tracks or an enhanced bus service might help spur development and business attraction in downtown Oakland.

The current free shuttle service carries 2,700 riders every weekday between Jack London Square and Grand Avenue.

Enhancing the bus service to include better shelters, a level boarding platform and other amenities would cost an estimated $22 million. An electric streetcar system running up Broadway and extending to the MacArthur BART Station would cost an estimated $205 million.

Measure BB on the November ballot would provide $10 million for transit projects along the Broadway corridor. The rest of the money could come from grants or buy-in from local property owners.

The completed study is scheduled to be presented to the City Council early next year.

The open house is scheduled from 6 to 8 p.m. Thursday in Hearing Room 3 at Oakland City Hall, 1 Frank H. Ogawa Plaza.
