The City of Montreal is currently replacing the 2 Darwin Bridges on Nuns’ Island. These structures enable pedestrians and cyclists to cross under the boulevard’s four traffic lanes safely and enter West Vancouver park. The overall length of these reinforced cast-in-place concrete bridges is 37 m. This project won the "ACI - Quebec and Eastern Ontario Chapter" Infrastructure Award in March 2021.

The construction of the northbound bridge was completed in November 2020 while the southbound bridge will be completed in 2021. The architectural signature of these bridges was conceived by the Provencher-Roy firm so that it fit in with the Corot Tower designed in 1967 by the famous architect Ludwig Mies van der Rohe.

A very special type of concrete lies behind the architectural features of these curved bridges. The Darwin Bridges are the world first bridges to incorporate glass powder concrete. In fact, 10% of the ternary binder was replaced by finely ground recycled glass. Approximately 40,000 kg of cement will be saved and a total of nearly 40,000 kg of recycled glass will be used for this project (the equivalent of 70,000 wine bottles). The use of glass powder as supplementary cementitious material helped reduce by 40 tons the quantity of greenhouse gas (GHG) released into the atmosphere. This amount represents the quantity of GHG produced by a car driven for 200,000 kilometres.

The City of Montreal is seeking an Envision environmental certification for this $11 M project. The Darwin Bridges were designed in-house by the City of Montreal's bridge and material engineers. Radio-Canada’s famous television program “Découverte” featured a report on this project on April 11, 2021.
