Motorist who use the Thorold Tunnel should keep in mind that today is the day it's expected to close for about a week.
The tunnel was expected to close last Monday for two weeks, but the Ministry of Transportation delayed that due to unforseen circumstances.
The tunnel is now set to close at noon today and won't reopen till Monday, May 18th at 6am.
The closure is necessary so crews can switch traffic to the south tube as construction on the tunnel continues.
