EBC - Pomerleau PJCC will build the temporary crossing between île des Sœurs and Montreal for the scheme to replace the Champlain Bridge. The  bypass bridge will have a total of seven lanes, three in each direction plus a reserved bus lane as well as a pathway for pedestrians and cyclists.

The Government of Canada also announced the award of associated contracts for the temporary causeway-bridge project. A consortium of Dessau and Cima was awarded a US$6.1 million contract to supervise the construction site and LVM was awarded a US$1.2m contract for quality control services.

The temporary bridge will be in place until the île des Sœurs Bridge is permanently replaced as part of the construction of the St Lawrence project.

Construction of the temporary causeway-bridge will begin at the end of this month and should be completed by 2015.
