It was around 1920 that Anglophones began settling in NDG, resulting in the construction of numerous schools and churches. The Décarie Expressway opened to motorists in 1966, in time for Expo 67. The highway construction forced the displacement of 285 families and had a major impact on the neighbourhood, severing the easternmost part from the whole and leading to the area being referred to as 'Westmount-adjacent' (a term implying housing costs and lifestyles more on par with Westmount, one of the most affluent communities in North America, rather than NDG which as a whole is more middle class).
