About the preferred interchange option
Our preferred option replaces the existing Melling intersection and bridge with a new bridge and grade separated interchange, connecting directly to Queens Drive. Local examples of grade separated interchanges are the Dowse Drive and Haywards interchanges, although these examples have roundabouts where the Melling interchange has traffic lights.
The Diamond Interchange Connecting with Queens Drive option received the most support from the community during the public engagement in 2018. It was also the option preferred by RiverLink project partners as it has the greatest fit with flood protection measures and provides the best connection to a more compact city centre.
Further information on the preferred interchange option selection process, including the 2018 community consultation report, will soon be available on our website at www.nzta.govt.nz/melling-improvements.
