Construction of the Otaki to North of Levin Expressway will not start until 2022 at the earliest - it it goes ahead at all.
The Labour-led Government is still to release its policy statement on the roading.
According to Stuff, the road's project manager, Lonnie Dalzell, gave Horizons Regional Council's regional transport committee an update on the road on Wednesday
All options for an expressway to the east of Levin have their problems, but the project manager says they are better than going to the west of the town.
A longlist of options for the NZ Transport Agency gave routes both to the east and west of Levin, but has since been whittled down to options solely to the east.
Many have criticised going east, as 75 per cent of people who took part in early engagement about the routes wanted it to go to the west.
Dalzell says going to the east would improve traffic flow better. Now its about working out the best routes for balance of safety and travel time
There are three options for the southern section of the expressway
Dalzell says the New Zealand Transport Agency board would pick a preferred option in mid-2018, after which it would take 18 months to create a detailed business case.
The consents process would then take another 18 months, but could be delayed if there were appeals taken to the Environment Court.
