Just weeks after it opened, the $2.2 billion San Francisco's Transbay Transit Center was abruptly closed on Tuesday. A major crack was discovered in one of the building's steel support beams.

According to a statement from the Transbay Joint Powers Authority, the beam was located in the ceiling of the third-level Bus Deck, and the decision to close was made "out of an abundance of caution," as engineers inspect other beams and work to repair the problem.

The Bus Deck is above the ground level. The structure's two other levels are below-ground floors that were designed for rail lines but aren't yet in use.

The San Francisco Chronicle reported that the beam is among many that support the rooftop garden.

Sitting on top of the transit center is a 5.4-acre park space that includes foliage, and numerous seating areas.

Firemen were on the scene and an officer of the San Francisco Police Department told Business Insider the building was being evacuated. Police were not allowing anyone near the four-block-long structure.

At least two of the city's major traffic arteries were closed, including Fremont and Beal streets between Mission and Howard.
