Two state Department of Transportation employees were taken to the hospital today after getting burned in a flash fire that occurred while they were making repairs to an overpass bridge on Route 128 in Waltham, officials said.
The employees were trying to fix a leak on the Route 117 bridge, which hangs over Route 128, said Sara Lavoie, spokeswoman for the Department of Transportation. While drilling, they hit some electrical wires, which caused the fire, she said.
One of the employees was taken to Newton-Wellesley Hospital where he was treated for minor burns to his hands and released, Lavoie said. The second employee was taken to Massachusetts General Hospital, where he is being treated for burns to his face.
