State Highway 1

  •   What does SH1 look like and what’s it like to drive on?

    While SH1 is open, the rebuild work is not completed and some areas are still construction sites. There are some unsealed surfaces, lane closures and stop/go at remaining works sites along the route.

    SH1 to the north of Kaikōura looks quite different in many places; new sections of highway have been built, along with a new bridge at Irongate and the road has been moved closer to the sea at some locations.

    There are speed restrictions and no stopping zones along the worst affected areas to the north and south of Kaikōura.

    Close
  •   Is the road open 24/7?

    Yes, since 30 April 2018.

    Prior to that, two of the most earthquake damaged sections of the road were closed overnight (7.30pm to 7.30am) as a safety precaution. They were (north of Kaikōura) between the Clarence and Mangamaunu and (south of Kaikōura) between the SH1/Leader Road intersection, which is north of Cheviot and Peketa.

  •   How long will it take me to drive SH1, compared to the alternate route (via state highways 63, 6, 65 and 7, through Lewis Pass)?

    Drivers now have two good options for travel between Picton and Christchurch – you need to decide which route is best for your needs.

    You should allow 5.5 hours to drive from Picton to Christchurch on SH1 (one hour longer than pre-earthquake).

    The ‘alternate route’ remains a good 24/7 option and you should allow around 6.5 hours.

    Unexpected events such as large weather events, a crash, high volumes of traffic or seismic activity can cause delays so it’s important that travellers allow plenty of time in case something happens.

    You should regularly check the Transport Agency’s dedicated web page – www.nzta.govt.nz/p2c (external link) or call 0800 4 HIGHWAYS (0800 44 44 49) for the latest information before you travel and at key decision points on your route.

    If SH1 is closed for any reason (or you’re travelling on the alternate route) Kaikōura can still be accessed via the Inland Road (Route 70) from Waipara.

    Close

  •   Is there ongoing work along SH1 in 2018?

    Yes. Work continues to ensure the route stays safe and resilient for the future.

    Crews will also be working to deliver the Government’s $231 million safety and amenities improvements package on the 60km section of State Highway 1 between Clarence and Oaro which will ultimately provide a higher level of service on the road for people living in the area, visitors to the region, and those travelling through.

  •   How reliable will SH1 be and should I consider using the alternate route to avoid missing my ferry/flight

    You have two choices for travel in the upper South Island and will need to decide which route is best for you. Whichever route you choose to travel, please allow plenty of time in case of delays so you can get to your destination safely.

    If you need to make a ferry, flight or other booking you may decide to take the alternate route as it has a more reliable journey time. 

    We are rebuilding SH1 to be safer through the worst affected sections. If there is a lot of rain or another significant event, we may have to close the road for short periods of time. The safety of those using the highway and working on the road will always be our top priority.

    Close
  •   What driving advice should I follow on SH1?

    Allow plenty of time in case of delays. Be prepared with food, water, and a fully charged cell phone.

    For everyone’s safety, strictly adhere to all road signage and speed restrictions. Follow any instructions by road crew.

    It’s important to ‘drive to the conditions’ and that means more than just the weather. It includes driving in an appropriate way for the road you’re on, the vehicle you’re in, the other traffic around you, and your level of experience.

    Be patient, cautious and courteous. The road conditions will be unfamiliar to many drivers so a little bit of patience will go a long way.

    Keep fresh by taking breaks, and support businesses in the local communities on the route.

    Close
  •   Is there anything I should know about driving at night on SH1?

    People can expect to see:

    • Multiple sections where traffic moves to a single lane, which will be controlled by traffic signals rather than current daytime Stop/Go controls.
    • New signage including ‘no stopping’ and ‘rockfall’ signs (in addition to existing mesh and physical barriers) to protect road users and alert them to potential danger.
    • Trains travelling day and night in either direction between Blenheim and Christchurch: drivers should take care at level crossings and check both ways before proceeding
    • Different types of traffic using the route including an increase in heavy vehicles, for example trucks and buses. Cyclists are advised to only use the road during the day for their own safety – due to multiple traffic lights and rockfall/no stopping areas.
    • That there will continue to be no stopping or camping in the two most earthquake-damaged areas just north and south of Kaikōura.

    Road crews will be carrying out regular observations and inspections of the route throughout the night.

    Close
  •   Can I cycle along SH1?

    Yes. Cyclists must obey all signs and crew instructions. Cyclists may need assistance or be escorted in some areas. Cyclists are advised to only use the road during the day for their own safety – due to multiple traffic lights and rockfall/no stopping areas.

    Close
  •   Can I take the train?

    KiwiRail is working hard to get the track ready for passenger trains but they won’t be running until later in 2018. The Main North Line between Blenheim and Christchurch is now open to freight trains in a limited capacity at night so that the rebuild of the road and rail can continue during the day. The internationally acclaimed Coastal Pacific tourism experience will be up and running when the rail line is fully complete and all of the speed restrictions are lifted.

    Close
  •   What has changed along the railway line?

    As with the road, a lot of work has been done to reinstate the railway line. Generally the rail line remains in the same place relative to the road along the route. However in some areas through the narrow coastal sections road and rail have been moved closer together on a temporary basis until permanent re-alignments of road and rail are completed.

    Travellers will notice the work to stabilise the slopes above the rail line and the fences and other structures now in place to protect both the rail line and road from further slips They will also notice some of the rail tunnels are being extended with rock fall shelters.

    Everyone should stay off the rail line at all times, only cross at official level crossings, and expect trains at any time in either direction.

Alternate route (state highways 63, 6, 65 and 7, via Lewis Pass)

  •   What is it like to drive the alternate Picton to Christchurch route?

    Travelling the picturesque alternate route (via state highways 63, 6, 65 and 7, through Lewis Pass) between Picton and Christchurch takes on average 6.5 hours but allow extra time as delays are likely. Journey time on this route is quite consistent. The alternate route is challenging to drive in places – it is narrow and winding in many places, with single-lane bridges and there are speed restrictions. For everyone’s safety, strictly adhere to all road signage and speed restrictions.

    Drivers need to be patient, cautious and courteous – if needed, pull over and let traffic behind you pass when it is safe to do so to prevent drivers becoming frustrated and making poor overtaking decisions.

    Do not drive when you’re tired; tired drivers are slower to react, make poor judgement decisions and find it harder to concentrate. There are rest stops with fuel, food, coffee and toilets at Culverden, Springs Junction, Murchison and St Arnaud. Take your time: stop for regular breaks at towns along the route and make the journey part of your holiday.

    Be prepared for unexpected delays with food, water, and a fully charged cell phone.

Safety

  •   Is SH1 safe to drive?

    Safety is the number one priority.

    Crews working on the road are monitoring work sites and traffic and ensuring that any issues are dealt with quickly.

    Close
  •   Why is it safe to drive at night from 30 April but not before?

    An extensive construction programme has been delivered over the last year and the critical safety work was completed by 30 April.

    More than 30,000 square metres of steel mesh has been wrapped around slips south of Kaikōura and new infrastructure such as bridges and seawalls has been built to the north. All of this construction work is designed to ensure the route stays safe and resilient for the future, with work continuing through 2018 to finish and improve the corridor.

    Close
  •   If there is an earthquake while I am driving on SH1 what should I do?

    If there is an earthquake while you’re on SH1 and driving through one of the work sites you must follow road crew instructions at all times.

    The Official New Zealand Road Code advice about driving during an earthquake is as follows:

    In a severe earthquake driving can be very difficult because the road may be shaking or moving up and down beneath you.

    If you think that an earthquake is happening while you're driving, you should:

    • pull over and stop
    • stay inside your vehicle until the shaking stops. Your vehicle will provide you with some protection against falling objects.

    After the earthquake:

    • if power lines have fallen onto your vehicle, stay inside it until help arrives
    • if you continue driving straight after the earthquake, be on the lookout for slips or other road damage and obstacles
    • turn on your radio and listen for news about possible road closures and other information.

    HPMV (H) vehicles and 50 MAX restricted to a height of 4.25m Yes – with relevant permit  
    Overweight vehicles or loads Yes – with relevant permit There may be additional speed restriction on overweight permits covered by a blanket addendum sent to permit holders.
    Over-dimension vehicles or loads

    Yes – if you fall into Category 1 and do not exceed 3.1m wide

    No – if you exceed the Category 1 width limits or any other Category– must continue to use alternate route via Springs Junction.

     
    Close
  •   Why is the route restricted to a height of 4.25m?

    The Transport Agency had planned to improve the current dimensions of the tunnels on SH1, however due to the earthquake this work was disrupted.

    Any trucks greater than 4.25m height that meet the new Vehicle Dimension and Mass rules will need to use the Inland Route to Kaikōura until further notice – this includes after SH1 opens 24/7. We will let the freight industry know when the tunnel dimensions have been increased but it is expected mid-2018.

    All drivers need to be cautious going through the tunnels and stay to the centre of the lane.

    Close
  •   Where can heavy vehicles stop on SH1?

    There are no truck stopping zones in the most earthquake damaged areas both north and south of Kaikōura as these are still construction zones. Even when the route reopens 24/7 there will be no truck stopping zones. Any drivers wanting to stop in the area should stop in Kaikōura.

    Operators and drivers must plan rest breaks to comply with the Worktime Rule provisions, the lack of rest and stopping areas cannot be used as a reason to not comply with these provisions.

    Close
  •   What is SH1 like for heavy vehicles to drive?

    There are some unsealed surfaces, lane closures and stop/go at remaining works sites along the route. SH1 to the north of Kaikōura will look quite different in many places; new sections of highway have been built, along with a new bridge at Irongate and the road has been moved closer to the sea at some locations.

    All drivers will need to take care, obey signage and adhere to all temporary speed limits.

    Truck drivers need to take extra care when coming in and out of the construction zones and keep at 10k below the advisory speed on corners.
