Tunneling Summary 2013
One of the most important features of the Confederation Line project is the 2.5 kilometre tunnel under Ottawa’s downtown core. During tunnel construction, three accesses are being used to bring in equipment, crews and materials, as well as to remove debris: West Portal, East Portal, central shaft.
What direction are the roadheaders heading?
West Portal tunneling is moving east toward Lyon Station. Central shaft tunneling will move east toward Parliament Station. East Portal excavation is moving north and west toward Rideau Station, linking underground to the central shaft and West Portal tunneling.
How far has tunneling progressed since starting in November 2013?
