A seal-widening programme on State Highway 2 at Whirinaki and the installation of a new right-turn bay will lead to slight delays for motorists this week.
The work is being done at the intersection of SH2 and North Shore Rd and speed restrictions and stop/go signalling are in place.
The work is one of several projects being carried out by New Zealand Transport Agency contract crews on SH2 north of Napier and people travelling the stretch are asked to be aware and to stick to speed restrictions.
An annual water-blasting programme of some sections as well as road marking at sites between Morere and Wairoa are being worked on and slight delays are likely.
"Please be patient when passing these vehicles as they move slowly when carrying out these tasks," an NZTA spokesperson said.
Crews are also working on drainage maintenance at sites between Tangoio and Putorino.
Similar work is being carried out on SH2 south at sites between Paki Paki and Waipawa where speed restrictions are also in place, as well as on SH5 between Napier and Taupo at various sites from Eskdale to Tarawera.
Motorists using the Hawke's Bay Expressway between Westshore and Longlands Rd can also expect to come across slow-moving road-marking vehicles although the NZTA said delays on the stretch would be "negligible".
At the region's two major roadworks sites speed restrictions are in place but delays are expected to be minimal.
A new road layout is now operating at the intersection of the SH2 expressway stretch and Watchman Rd, while restrictions are in place at the Whakatu Arterial site at Mangateretere.
