The section of State Highway 2 between Pahīatua and Mangatainoka will undergo resurfacing work over the next two days.
A detour will be available for light vehicles, but Waka Kotahi NZ Transport Agency says this will not be suitable for heavy vehicles.
Waka Kotahi spokesperson Jaclyn Hankin said stop/go traffic management would be in place while work was under way.
Hankin said there will be delays of up to 20 minutes due to the length of the work site, with the detour available for light vehicles that choose not to wait the 20 minutes.
Work will take place today and tomorrow between 7am and 5pm.

In a low scoring game at the OngaOnga Domain on Saturday, the Waipawa Butchery CHB Premier cricket team won a tight encounter with Havelock North to reach the final of the MJF Shrimpton Memorial 50-over competition.
Havelock North batted first, and were bowled out for 125 in 42 overs on what was a good batting wicket.
For Central, Toby Richardson took 4 wickets for 23 runs off 10 overs, Angus Schaw 2 wickets for 6 runs off 10 overs, and Rythm Sharma fished on figures of 2 wickets for 19 off 6 overs.
In reply, Central lost their first wicket at 23, and with wickets falling regularly after that, a win to Havelock North looked odds on.
Skipper Dom Thompson lead the way with a fine 62 not out to secure Central a finals spot for the MJF Shrimpton trophy.
The final will be against Napier Tech Old Boys at Nelson Park this Saturday.
