Lakeshore Rd. was closed between LeCaron Ave. and Egmond Dr. early Monday afternoon after a car struck a gas line and rolled onto its side.
Sarnia police say the vehicle was travelling westbound around the curve when it lost control and rolled over onto the north side of Lakeshore Rd.
Union Gas attended the scene and shut the line off.
The driver was taken to hospital with what were believed to be minor injuries.
The road was closed for a short period of time and has since reopened.
The investigation is ongoing.
