In the 1970s the integrity of neighbourhood was threatened by proposed high-speed transportation routes and by increasing land development. It was proposed that Memorial Drive become a major highway and an interchange be built where Memorial Drive and 10th Street NW intersect today. The Louise Bridge would be replaced by two new bridges; a southbound bridge aligning to 10th Street NW and a northbound bridge aligning to 9A Street. The association adopted an activist approach, and succeeded in blocking the interchange plans and retaining much of the traditional small-scale quality of the community.
