Motorists are reminded to leave extra time when travelling around the Bay of Plenty and Waikato over the coming months as work on major projects and roadworks ramps up.

Transport Agency work crews are out in force at the moment, making the most of the warmer, dryer weather to make highways safer and progress projects such as the Waikato Expressway and Maungatapu Underpass in Tauranga.

Contractors will be carrying out road works around the Bay of Plenty for the next few weeks.

'Drivers are likely to encounter speed restrictions and other traffic management at roadwork sites which may cause delays and should get in the habit of allowing extra time for their journeys,” says a statement from the NZTA.

People can get information on road works and detours in the region they are in, or travelling to by checking www.nzta.govt.nz/summerjourneys, by calling 0800 444 449 or following the Transport Agency on Facebook or Twitter.

Bay of Plenty travellers can also go to www.drivelive.nz/tauranga , a dedicated website that tells drivers what the current travel times are to get to key places.

Roadworks sites which may cause delays are detailed below to help people plan head when travelling:

Bay of Plenty

SH36 Mangorewa Gorge between Rotorua and Tauranga

Motorists travelling between Tauranga and Rotorua on SH36 are advised to expect delays this month as contractors carry out rockfall prevention work in the Mangorewa Gorge.

Speed restrictions and traffic lights will be in place at times from February 22 for approximately five weeks. Please allow an extra 10 minutes for your journey.

SH36 Tautau Bridge (just south of Pyes Pa School)

Speed restrictions will be in place at times from February 26 until April 30 while contractors carry out works on the bridge. Motorists are advised to drive with extra care in the area.

Rotorua area

Transport Agency contractors will be resealing a stretch of SH30A (Amohau Street and Te Ngae Road), between Fenton Street and Sala Street from 7pm Friday March 4 until Sunday March 6.

The work will focus firstly on the lanes heading towards the CBD (west/north) on Friday night, and on the lanes heading toward Lynmore and the Rotorua Airport (east/south) on Saturday night.

From 7pm until 10pm on Friday one of the two lanes heading into the CBD will be closed.

From 10pm that night until 7am both west/north-bound lanes will be CLOSED. Traffic heading in this direction will be detoured onto Sala Street and Fenton St.

From 7am until 9am on Saturday one of the lanes heading into the CBD will be reopened.

After both lanes reopen at 9am speed restrictions will be in place for the day due to the loose chip, and to allow the new surface to bed in.

Work on the eastbound lanes heading towards Lynmore and the Airport will start at 6pm on Saturday with the closure of one lane.

From 10pm that night until 7am on Sunday morning both the east/south bound lanes will be CLOSED and traffic will be detoured via Fenton Street and Sala Street.

The road will reopen to one lane at 7am on Sunday, with both lanes east/south bound lanes expected to be reopened by 9am.

50km/h speed restrictions will remain in place for the day due to the loose chip, and to allow the new surface to bed in.

All work, including roadmarking and sweeping of excess loose chip, is expected to be complete by Sunday evening.

The works have been planned so that access to businesses on this section of road, such as Pak'nSave, will be unaffected during their opening hours.

Roadworks and reseals will be underway on other sites around Rotorua over the next week, including:

• SH5 Mokia Drive

• SH30 Sala st

• SH36 Mangapouri Single lane bridge

Motorists are advised to allow an extra 10 to 15 minutes when travelling around the city on the state highway network.

SH2 between Tauranga and Waihi

Motorists travelling on SH2 between Tauranga and Waihi are urged to drive with extra care over the next two months as work continues on a major safety upgrade.

A section of highway between Wainui South Road and Sargent Drive will be repaired and widened, and a wire rope central median barrier installed to prevent head on crashes.

Work started in January and is expected to wrap up in early May.

People should only expect minor delays but are urged to stay alert behind the wheel as there will be significant changes including lane closures, speed restrictions and occasional stop/go traffic management.

Tauranga Eastern Link

The long-life road marking will be applied on the Tauranga Eastern Link expressway and motorway from February 22.

The works will be carried out at night for six weeks. The reason for the long time period is the paint is slow to apply and takes hours to dry.

A lane closure and 50km/h speed restriction will be in place.

Drivers are asked to take care when driving along this route.

Te Puke Highway

Motorists using the Te Puke Highway during March are advised to allow extra time when travelling, with road reconstruction work expected to cause delays.

Works are continuing along sections of the highway, which involve digging up and removing the old road and replacing it with new roading before sealing and roadmarking.

SH2 Karangahake Gorge

Fibre optic cable laying through the Karangahake Gorge (SH2) is under way until mid-March. Traffic will be managed through the work under speed restrictions but there will be occasional lane closures and stop-go needed – with a maximum delay of five minutes.
