The MTA is proposing to change more than 50 of its bus routes, create four routes and eliminate or consolidate about a dozen others as part of what state Transportation Secretary Robert L. Flanagan has called "the first comprehensive restructuring of our bus routes in the last 30 years."

The hearings on what the MTA calls its Greater Baltimore Bus Initiative will begin June 13 and continue through June 22. They involve proposed changes to the core bus service in Baltimore City and Baltimore and Anne Arundel counties, and to commuter lines to Harford and Howard counties.

The Maryland Transit Administration is proposing changes to the following bus routes: 1, 2, 3, 4, 5, 7, 8, 10, 11, 13, 14, 15, 16, 17, 19, 20, 22, 23, 27, 29, 31, 33, 35, 36, 44, 51, 55, 61, 64, 65, 68, 77, 86, 91, 102, 103, 104, 105, 150, 160, 310, 311, 320, 410, 411, 412, M1, M6, M8, M10, M12, M17, Hampden neighborhood shuttle Mondawmin neighborhood shuttle
