(CORAL GABLES) CBSMiami.com – A portion of MetroRail near the University of Miami was shut down Friday morning after a truck carrying waste bins smashed into one of the columns supporting the elevated tracks. It was re-opened after inspectors declared the column safe

The accident happened at Stanford Drive, near US1 in Coral Gables around 10 a.m. Metro transit officials shut down the tracks between the Douglas Road and South Miami stations, forcing commuters to leave the train and travel between stations via shuttle bus.

Nobody on board a train was hurt, and none of the trains were damaged. Transit officials closed the tracks as a precaution while they investigated the extent of damage to the support columns.

When the trains were again allowed to run, they were limited to a single track, which caused delays across the system as trains were forced to wait. Inspectors gave the all-clear before noon, and full service was restored.

The accident is under investigation.
