Tunnel construction for Confederation Line reaches 10 per cent milestone

The City of Ottawa says tunnel construction for the LRT's Confederation Line has reached the 10 per cent milestone.

The city says the machine named Jawbreaker has carved out 228m of the tunnel at LeBreton Flats and is now digging under Queen Street, just west of Bay.

Tunnel borer Crocodile Rouge has mined 22m from the East Portal near the University of Ottawa towards Rideau Street, while the third machine, Chewrocka, has crunched out 7m of the gallery that will lead from the construction shaft to the tunnel excavated near Queen and Kent.

The city says the project is on time and on budget.

The $2.1-billion Confederation Line is scheduled to be opened to the public in 2018.
