Residents south of Boyle were allowed to return to their homes May 22 after a tractor-trailer travelling on Highway 831 released hydrochloric acid after a single vehicle collision.
A section of Highway 831 located three kilometres south of Boyle was rendered impassable after the incident May 21, according to a Boyle RCMP press release the same date.
Ten residences were ordered to evacuate as a precaution, according to RCMP media relations Cpl. Leigh Drinkwater, but were allowed to return home at 1 a.m. May 22.
The cause of the collision is not yet known, Drinkwater said.
"That is still part of the ongoing investigation with the Boyle (RCMP) detachment. They have not made a determination yet as to cause," Drinkwater said in a May 22 interview, adding no charges have been laid in the case.
The road was re-opened overnight May 22, Drinkwater said, but limited to one-lane of traffic the next morning while crews worked on the scene.
Crews cleared the truck from the area, but Drinkwater said the damage done by the spill would take more time to determine.
"That won't be known until the cleanup is complete," Drinkwater said.
