Here is a Gazette story from today Aug 13 2014
The bridge, which has been under construction since August 2013, will allow the bridge agency to close and reconstruct the existing Nuns’ Island Bridge, which is planned as part of the replacement of the Champlain Bridge.
Like the existing bridge, the bypass will have three lanes each direction. The bridge will also feature a dedicated bus lane, and will also have widened bike lanes.
The agency says that the bypass construction will also allow them to remove a traffic light on Highway 15 which slowed down traffic to Montreal in the afternoon.
