Transport Quebec is about to remove more paralumes, this time on Highway 13 near a Trudeau Airport runway.
A public tender was issued last week for the removal of the concrete overhead light-filtering structures for a stretch of Highway 13 between highways 520 and 40.
The project, which will require lane closings, is expected to be done in the coming months and cost between $10 million and $15 million. That includes other work, including repaving Hwy 13 between highways 20 and 40.
On Monday, Transport Minister Sylvain Gaudreault is to announce details of the Hwy. 13 work when he outlines Quebec’s roadwork plans for Montreal Island.
The paralumes, spread across about 650 metres, were installed to allow drivers’ eyes to adjust as they enter and exit the Dorval Tunnel under part of the airport.
Their removal is included in a Transport Quebec list of “potential sites to improve road safety” this year.
But a department spokesperson said that does not mean it has safety concerns regarding the paralumes, which are similar to the ones that collapsed onto the Ville-Marie Expressway in 2011.
It’s a road-safety issue because the project will “improve visibility and brightness as drivers enter and exit the tunnel,” a Transport Quebec spokeswoman, Caroline Larose, said.
An investigation into the Ville Marie collapse found the paralumes were not to blame.
But Transport Quebec has said the structures are no longer needed and are being gradually phased out.
On highways where paralumes are being removed, new lighting is taking on the paralumes’ function.
“Technology has changed and there are new light fixtures that can ensure adequate lighting for the transition between daylight and the tunnel,” Larose said.
Transport Quebec had to close an entire downtown Ville-Marie Expressway access last Sunday in order to remove paralumes and do other repairs there.
Accessed via de la Cathédrale and Notre-Dame Sts., that entrance to the eastbound Ville Marie will reopen in late June.
