Fire crews are currently fighting a crane fire near the Walt Whitman Bridge in Gloucester City, New Jersey. The fire started just before 10 a.m. on Tuesday near the 100 block of Essex Street. It seems to have originated on a crane working on the cargo ship, Pacific Harmony. Although the fire is mostly under control, there may still be visible smoke in the South Philadelphia area, according to Philadelphia emergency management officials. Speeds on the Walt Whitman Bridge have been reduced, and delays into New Jersey are expected, according to the Delaware River Port Authority.
