The project team is working on park and ride and regular bus services that link to the existing cycling and walking network.
NZ Transport Agency's system design senior manager Brett Gliddon said the community showed strong support for the options at open days earlier this year.
"We have spoken with the community and the priority here is to prevent people dying or being seriously injured along this stretch of road," Giddon said.
"That is why we have started work on interim safety improvements at key intersections," he said.
"We will also be preparing for safety improvements such as wide centrelines and installing side barriers from next year and speaking more to the community about reducing the speed along State Highway 2," Mr Gliddon says.
