Starting next Friday, new traffic restrictions will be implemented on Rideau
Street between Sussex Drive and Dalhousie Street as part of the massive O-Train
Confederation Line project. The restrictions — in place until the line opens in
2018 — are required due to construction of the Rideau Station entrances and vent
shafts. via
