On the same day Mayor Jim Watson tweeted a photo showing both ends of Ottawa’s Confederation LRT tunnel meeting somewhere under Rideau Street, the National Capital Commission signed off on the city’s proposed alignment and functional design for the future western LRT extension along the Sir John A. Macdonald corridor.
Digging of the 2.5-kilometre LRT tunnel beneath downtown began at both ends and met somewhere in the middle, east of the Rideau Canal. There’s a western portal near the future Pimisi station, a central portal below Queen Street and an eastern portal at the University of Ottawa.
Watson’s tweet shows a muddy tunnel where workers first joined the two sides.
