Don't be surprised if you see a sizeable puddle in the Lafontaine tunnel.
It seems that this winter's harsh weather variations are wreaking havoc on the 47-year-old structure.
Transport quebec spokesperson Caroline Larose says harsh weather has aggravated leaks that have been around since the structure's inauguration in 1967.
"This section has always been problematic. But with colder temperatures and long days of such temperatures, we've noticed that there's more water coming on to the pavement."
Wanting to be reassuring, Larose insisted that "infiltration is normal in an underwater tunnel."
The issue is not a new one either. The Transport Quebec spokesperson explained to CJAD that the troubles began because of mistakes during the tunnel's construction.
"When the two last pieces of the tunnel were built and joined together back in 1967, the concrete was poured during the wintertime, so the temperatures weren't proper."
Transport Quebec is monitoring the condition of the tunnel hourly for the time being. Major work on the tunnel and highway 25 is expected to begin in the coming years.
