Six people were injured in one crash involving four motorcycles and two more were injured in a second crash involving two vehicles and a semi on Interstate 75 in Anderson County on Saturday morning, authorities said.

The two crashes occurred about 30 minutes apart in the northbound and southbound lanes of I-75 near mile marker 127, near Rocky Top (the former Lake City).

Two University of Tennessee Lifestar medical helicopters responded, and all four lanes were temporarily closed.

The first crash was reported at about 10:16 a.m, according to a Tennessee Highway Patrol preliminary crash report.

Four Harley Davidson motorcycles were traveling north in one lane of I-75 at mile marker 127 when the first motorcycle, a 2003 model driven by George Suver, 70, left the right shoulder and then swerved back into the lane, the THP said. [Read more…]
