Main Street access to Highway 12 set to close temporarily

Westbound traffic accessing Highway 12 from Martensville’s Main Street is guided by signage in the construction site

The Main Street intersection in Martensville at Highway 12 is scheduled to be closed for about a month beginning Sunday, August 12.

The temporary closure will facilitate the construction of access ramps onto the overpass bridge from Main Street, according to Andrew Schumacher, Project Manager with Peter Kiewit Sons ULC, the contractor building the Martensville and Warman Interchanges Project.

Currently, westbound traffic from Main Street in Martensville has been able to access Highway 12 by navigating through a maze of pylons marking the trail through the construction site.

However, beginning this weekend, that’s about to change, said Schumacher in an e-mail to the Gazette on Thursday, August 9.

“Video message boards are up indicating this closure and motorists are advised to follow the signs and traffic control devices,” said Schumacher. “It is recommended that motorists use the Highway 305 access to Highway 12. Detour signs indicate to use this option.”

However, there are two other routes that motorists can use if they prefer, added Schumacher.

They can access Highway 12 using the south entrance on Lutheran Road, or they can access Highway 11 through Warman using Township Road 384 (Main Street).

“There are no signs for these two options,” said Schumacher.

He said commuters that normally use the Main Street access to get to Saskatoon are advised to “head north on Centennial Drive, and then turn left (west) onto Highway 305, turn left again onto Highway 12 and travel southbound toward Saskatoon.

“If you are driving from Saskatoon to Martensville, access to Martensville will continue to be maintained via the 4th Street off-ramp which was opened earlier this year in a temporary configuration.”

He said the new southbound and northbound lanes on Highway 12 are now open, and will accommodate a single lane, in both north and south directions.

“Keep in mind, there are speed restrictions in place,” he said.

The completion of this portion of the project is expected to take 30 days, which will put into the second week of September, a few days after the Labour Day long weekend.

The actual date when the intersection will reopen in its new configuration will depend on the weather.


Schumacher said construction is also progressing as planned on the Warman overpass on Highway 11. He said motorists will see some changes beginning next month.

“By September, 2018, the project is planning to open one lane on Highway 11 northbound, and the Highway 305 access will also be partially opened,” he said. “This is in order to begin construction on the southbound Highway 11 tie-ins to the new highway infrastructure in the latter portion of 2018 or early 2019.”

Schumacher said the actual completion of this project is weather dependent.
