Yes. With commuter and freight traffic using the Christchurch Northern Corridor, traffic volumes on Main North Road and Marshland Road will drop significantly. This will reduce congestion, improve travel times for all road users and improve amenity for local residents. It will also assist in making these roads safer for all users including cyclists and pedestrians and free up room for public transport facilities.
Our traffic modelling shows that by 2026 the number of vehicles on Main North Road (Redwood) per day will be 42,000 if the Christchurch Northern Corridor is not built and 24,000 if it is built. Traffic volumes on this road in 2015 were 35,000, a result of changes in travel patterns since the earthquakes.
There were 15,000 vehicles a day on Marshland Road in 2015. By 2026 there would be 29,000 vehicles a day if the Christchurch Northern Corridor is not built or 18,000 if the Christchurch Northern Corridor is built.
By 2026 42,000 vehicles a day will use the Waimakariri to QEII section of the Christchurch Northern Corridor.
(This modelling is based on post-earthquake traffic flows and updated development and growth predictions, and assumes the Western Belfast Bypass, another NZ Transport Agency project, is built. By 2026 the Western Belfast Bypass will carry 24,000 vehicles a day.)
