Drivers in the Greater Montreal area can expect to get some traffic relief this winter as the northtube on the Louis-Hippolyte-La Fontaine tunnel, connecting the Island of Montreal to the South Shore, is set to re-open.
The reopening of the northtube expected on Dec. 1 will bring the total open lanes to four — two on each side — of the six lanes in the tunnel.
In a social media post, Quebec’s Ministry of Transport and Sustainable Mobility shared an update last week saying the repair work was progressing on schedule, without specifying a date.
Work on two other lanes are expected to continue through the spring. All six lanes of the tunnel is expected to fully open for traffic in the summer of 2027.
The ministry began the $2.8 billion project to repair the structure and modernize the equipment in 2020. The rehabilitation was originally estimated to cost $900 million and to be completed by November 2025.
The tunnel was originally built in 1967.
