One of the access ramps to the Mercier Bridge was closed Monday morning in preparation for re-decking of the bridge.
The ramp coming from Highway 138 heading towards Montreal from the south shore town of Chateauguay was closed.
The federal body overseeing the repairs, the Jacques Cartier and Champlain Bridges corporation, says the ramp will be closed for about three or four months.
The actual re-decking is slated to start in three weeks.
The whole project should take two or three years to complete, say officials.
Meanwhile, drivers coming from Chateauguay have been re-directed to the Mercier Bridge via Highway 132, meeting up with traffic from Candiac and Delson.
However, officials are happy with the morning's traffic situation -- saying delays only cost drivers approximately 15 minutes extra, on top of the usual traffic.
