Mercier bridge to South Shore closed

Drivers headed to the South Shore will now face a major detour. Traffic on the Mercier bridge to Chateguay has been suspended until further notice. The lanes to Montreal will remain open.

The Quebec Transport Department made the announcement Tuesday night, citing undisclosed safety reasons. Officials would not say what is wrong with the structure. They did say that the closing is expected to be temporary. The side of the bridge heading to the South Shore was built in 1934.
