The council had to consider flyover alongside examining the entire network, particularly the Levin to airport corridor, he said.
The options, including a tunnel, were assessed on a number of criteria, including how they would affect the economy, the look and feel of the city and Basin Reserve area, public transport, walking and cycling, traffic volumes, journey times - and what could be done to mitigate less desirable effects.
About 25,000 vehicles enter the Basin Reserve from Kent Terrace each day, about 20,000 from the Mt Victoria Tunnel and more than 11,000 from Adelaide Rd. Congestion causes delay and makes travel times unpredictable, especially at peak times and weekends.
The council said it would write to Environment Minister Amy Adams requesting that any application for resource consents to build the flyover was heard by the Environment Court rather than a Board of Inquiry.
