Tree felling, bridge work and surface water-blasting along stretches of SH5 between Napier and Taupo this week could mean delays which may impact travel times by up to 15 minutes.
Contractors are setting to work on a re-surfacing of the Lucky Hill Bridge just north of Eskdale, with New Zealand Transport Agency journey manager Oliver Postings advising there will be delays.
"As this is a tight and constrained site we will need to implement a single lane and stop-go (signalling)."
"There will be delays so please be patient."
Stop-go signalling will also be in place at the site of tree removal work around Te Pohue.
Some of the felling will involve trees near the highway so there will be delays at times, Postings said.
On the stretch between Te Pohue and Tarawera contract crews will be carrying out surface water blasting and temporary speed restrictions will be in place, along with stop-go signalling.
Similar restrictions, which will also likely affect travel times, are in place at sites along SH2 north and south of Napier as well as SH50.
On SH2 north around Nuhaka surface repair work is being carried out while drainage maintenance is under way at sites between Putorino and Tutira.
Road marking work is also taking place around Kereru Rd on SH50 as well as road marking at sites between Hastings and Takapau and motorists have been asked to drive with caution in the work areas as the contracting vehicles will be moving slowly.
On SH38 between Wairoa and Lake Waikaremoana drainage maintenance is being carried out around Ohuka with temporary speed restrictions in place.
