In order to meet the 42-month construction deadline, many steel and concrete bridge elements were prefabricated, with a portion of the work taking place on temporary piers.
Three jetties were built: one on the east from Brossard, one on the west from Nuns' Island, and one from the center, adjacent to a dike along the Saint Lawrence Seaway.

The pier through the canal, allowed, by means of cofferdams, the storage of piles of construction material.

The central jetty served as a construction platform for the piers and towers of the section of the bridge utilizing guy-wires.
Temporary pillars used during the construction of the Millau Viaduct in France were erected to support the cable-stayed span during construction.
The main cable-stayed span above the seaway was assembled in segments by means of a crane.

The 500-meter (550 yards) long west pier was divided into three pre-assembly areas: a first for the concrete foundation footings that serve as the base for the viaduct section crossing the river, a second for the steel headers that complete the piles, and a third for the steel superstructures that wear the aprons.
During the prefabrication of the 38 marine insoles, a pile primer and working platform were added to form a pile base measuring up to 14 meters (45') high.
A super-transporter moved these stack bases from the prefabrication area to a loading area from where they were lifted by an industrial catamaran.
The catamaran then deposited these bases in spaces drilled to a depth of 4 to 5 meters (15') in the riverbed.
Two floating cranes finally overlaid the bases of the prefabricated elements to form piles and headers.
The steel box girders supporting the three decks of the bridge were then deposited on the trimmers as they were completed.
