The NZ Transport Agency is advising Bay of Plenty and Waikato motorists to start their journey online and plan ahead to avoid delays as road works season ramps up.

Transport Agency work crews will be out in force over the next five months, making the most of the warmer, dryer weather over summer to make highways safer, and progress major projects.

Drivers are likely to encounter speed restrictions and other traffic management at roadwork sites over the next few months, and should get in the habit of allowing extra time for their journeys.

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

Journey manager Nigel D'Ath says checking out the Transport Agency's website before packing up the car can help people choose the best routes and times to travel.

'Picking up your mouse or your smartphone before you pick up your keys and planning your journey could save you a lot stress and unnecessary time on the road,” Mr D'Ath says.
