A tractor-trailer truck has spilled sulphuric acid on Highway 103 in Yarmouth County, forcing part of the highway to be closed, according to RCMP.

RCMP Const. Mark Skinner says the incident happened near Exit 31 at Pubnico. It was carrying several barrels of the acid.

Initially, RCMP said the truck had tipped over, but police later said a barrel in an enclosed trailer came loose and leaked.

Crews are now on the scene. The driver was not injured.

A Hazmat team was brought in to clean up the spill. Police say they expect the highway to be reopened around 11 p.m.

The highway has been closed between Exit 30 near Barrington and Exit 32 near Argyle.

Traffic is being diverted to Trunk 3. Police say they're not sure when the section of highway will reopen.
