Delcan will lead a multi-disciplinary team of consultants comprised of engineers, planners, architects and other relevant specialists including Halcrow to complete the downtown Ottawa transit tunnel (DOTT) planning and environmental assessment. The study will develop a plan for transit through the downtown core, within a study area spanning from Bayview to Ottawa's VIA Rail station. The DOTT study will consider main transit routes through downtown, the role of Bayview and Hurdman stations as potential interim transfer points, opportunities for interprovincial linkages, and potential connections to the Via Rail station. The study is expected to take approximately 20 months to complete. Public consultation will be a part of the study. The tunnel is expected to cost CAD500 million to CAD1 billion.
