As part of Phase 1, concept alignments were developed for all corridors under consideration. Corridor 6 (Lower Duck Island) was described broadly as a connection between Highways 50 and 417 via Lorrain Boulevard and Ottawa Road 174. During the environmental assessment process, it is necessary to study “alternative alignments or designs” to accomplish the same objective.
