Man climbs to top of Tobin Bridge; traffic halted as negotiators try to talk him down

UPDATE: 9:07 p.m. Negotiators succeeded in talking him down and he's now in police custody.

The Tobin Bridge is shut to inbound traffic as Boston and State Police negotiators try to convince a man who climbed the girders up to the top to come down. Just in case, the Coast Guard and the Boston Fire Department have personnel stationed on and near the Mystic River.
