OSHA is investigating an accident at a construction site in South Lake Tahoe, where a construction worker was critically hurt Tuesday. Emergency crews were called about 7:30AM to the accident at the site of a condominium roject behind Harrah’s on the south shore. The site is just on the California side of the state line. A construction worker was standing in a manhole that was inside a dug-out pit when he was hit by a pickup being driven through the pit. He sustained critical injuries to his chest and shoulder and was flown for treatment to a hospital in Reno. Eric Guevin with Tahoe Douglas Fire says he expects no charges will be filed, since it was an accident, but he says OSHA could issue a fine after an investigation.
