The design of the new bridge was unveiled this morning by federal infrastructure minister Denis Lebel, along with a video which takes drivers on a virtual crossing of the future span.
The federal government announced in October it would build a new bridge to replace the deteriorating Champlain, the busiest bridge in Canada.
The new bridge will stretch from the South Shore to Montreal in one long span divided into three segments.
Inbound and outbound traffic will have their own independent lanes on the bridge, as will public transit.
There will also be lookout points for pedestrians.
Poul Ove Jensen, the Danish architect behind the bridge design, says the structure will be unique to Montreal.
"I think it has the potential quality of a landmark and I think it is instantly recognizable,” he said.
Six consortiums responded to a call for qualifications issued by the government to build the bridge. The three that receive the highest marks will be invited to submit a proposal in the next few weeks, Label said.
At least 16 homes will need to be expropriated for the project, which is expected to cost between $3 billion and $5 billion by the time it opens.
