Emergency crews have extricated a semi-trailer driver from his vehicle following a rollover on Highway 7 and the north Perimeter Highway just outside Winnipeg this afternoon.

RCMP say the five-ton truck was trying to take the Highway 7 off-ramp eastbound onto the Perimeter at around 1:30 p.m. Thursday when the driver lost control of the vehicle and and it flipped onto its side.

Local firefighters and emergency personnel removed the male driver from inside the semi. RCMP did not have any details about injuries.

Police are asking motorists to slow down and drive carefully in the area on Thursday afternoon, as traffic delays are expected.

RCMP traffic services officers are investigating.
