All four lanes of the Trans-Canada Highway east of Regina will be open to traffic, starting Friday.

Lane restrictions have been in place on Highway 1 for more than four months as crews work to build a bypass around the city.

“We understand that people living in the Regina area have likely been delayed by Regina Bypass construction over the last number of months,” Saskatchewan Highways and Infrastructure Minister David Marit said in a news release.

“We would like to thank everyone for their patience and understanding. Work remains on time and on budget and about one year from now, new overpasses at Balgonie and White City will be open to traffic, providing a long-term improvement to safety issues on Highway 1 East.”

Temporary traffic signals will remain at the intersection of Highway 1 and Highway 48 while the White City overpass is being constructed.

The speed limit will be increased to 80 kilometres an hour on most sections of Highway 1 East. Drivers will have to slow down to 60 km/h in the overpass construction zones near White City and Balgonie.

Officials say other ongoing work along the corridor will require reductions to one lane and 60 km/h.
