The crash happened about 9 a.m. in the 1100 block of Shaw Mill Road.
The road reopened Friday afternoon.
Authorities said two people were injured when their vehicle ran off the road, then struck and ruptured the gas line.
The driver has been identified as 68-year-old Floyd Croxton, and the passenger has been identified as 62-year-old Julius Mitchell.
They both were taken to the hospital for injuries they sustained during the crash and have since been released.
Police said Croxton appeared to be suffering from a seizure when the crash happened.
