BOSTON — The area near the Boston Marathon finish line where two bombs killed three people is slowly coming back to life.

Authorities have yet to re-open all of Boylston Street, but Boston police on Tuesday morning allowed traffic and pedestrians to cross Boylston on Clarendon Street for the first time since the Patriots’ Day bombings.

The city’s landmark Trinity Church, traditionally a place for worship and comfort during times of crisis, began to buzz back to life as employees trickled in after more than a week away. The church isn’t yet open to the public, but employees readied “open for prayer” signs they will post along Copley Square as soon as police allow them to.

Federal investigators on Monday have formally released the crime scene to the city.
