The Christchurch Northern Corridor (CNC) Alliance is the head contractor on a $240 million project which sees the Main North Road and the Western Belfast By-Pass converge with the new Northern Corridor just south of the Waimakariri River.
Currently the Alliance is engaged in a 16 month long project adding additional traffic and cycle lanes to the existing twin carriage Waimakariri River bridge, a structure commissioned and built in the early 1970s.
