Kia ora,
My questions relate specifically to options considered for increasing State Highway capacity between Petone to Grenada and Transmission Gully. This may be upgrading the existing SH1 section, or through a new link road (a so-called 'Takupu Link').
Such options were discussed in 2015 here: https://nzta.govt.nz/assets/projects/pet...
I am requesting information later than Nov 2023 relating to similar schemes.
Yours sincerely,
Timothy Parker
