Weekend traffic: Champlain Bridge closure and marathon will cause woes

Transport Québec’s plan to close the inbound Champlain Bridge and the Montreal marathon will make driving more difficult around downtown, the southwestern part of the island and the east end this weekend.
The bridge will be completely closed to traffic headed toward Montreal on Sunday morning, Transport Québec announced in its weekly roundup of weekend road closures.
This Saturday and Sunday will also feature street closures on Montreal Island for the Oasis International Mara
