NZ Transport Agency Waka Kotahi (NZTA) encourages people travelling between the West Coast and Canterbury on SH73, the Arthur’s Pass route, to check the dates they are travelling in advance.
There will be delays in December – up to an hour - at two key bridges – on different days.
People can check the NZTA Journey Planner or Traffic and Travel pages to see where delays could be encountered on the trip.

At McGrath Creek Bridge near Arthur’s Pass, contractors will be installing new bridge beams (to make the bridge wider and eventually into two lanes) over three days in December, Tuesday to Thursday, 10-12 December, between 10 am and 3 pm.
This bridge will reopen at the top of each hour between 10 am and 3 pm to let traffic through in either direction, so drivers could face up to an hour’s delay.
The Bealey River Bridge is getting its handrails repaired over one Sunday night 15 December. The crew will be on site 6pm to 6am with the first closure for 50 minutes at 7.10 pm and the last one at 5.10 am.
Overnight and evening drivers between the West Coast and Canterbury need to factor in the delays on that night. The bridge will be open as usual up till 7.10 pm on 15 December.
There is likely to be other work occurring on the Canterbury-West Coast highway network with Stop/Go control (5-10 minute delays) in the lead-in to the Christmas shut-down. Drivers travelling between the West Coast/Buller and Canterbury, or Canterbury and Nelson should allow a bit more time for these minor additional worksites, pack some cold drinks and snacks and enjoy some chill time.
