RCMP have reopened the southbound lane of Highway 63 where a semi-trailer rolled Friday, spilling natural gas condensate.
However, northbound traffic near Boyle is still blocked Saturday morning as clean-up crews contain the spill.
The driver of a semi-trailer hauling the hydrocarbons lost control Friday, and the truck rolled across the centre median, according to police. No one was injured.
Initially, workers shut down the highway to keep the public out of a 300-metre perimeter for the mop up.
Northbound lanes of Highway 63 are expected to be closed for several more hours Saturday. RCMP recommend drivers use Highway 881 as an alternate route.
