Two return convoys have managed to get through Haast Pass today as Waka Kotahi opened a single lane on the vital storm damaged route along state highway six. Muddy Creek Bridge north of Makarora was buried in a massive slip in last week's extreme weather with debris initially piled four metres high. The road's a vital tourist route linking Haast, Fox Glacier and Franz Josef to Wanaka and Queenstown. Escorted convoys of light vehicles were allowed to drive a single lane along the route at midday and four thirty this afternoon. Waka Kotahi says there are two excavators, two loaders, five trucks and a bulldozer working in confined and challenging spaces to get the job done as quickly as possible. Development West Coast CEO, Heath Milne speaks to Lisa Owen. An update from Waka Kotahi: From tomorrow morning all vehicles, including busses and those weighing over 5 tonnes can use the road. It will be by escort at 8am, 12pm and 4.30pm. The length of the guided convoy route is just under a kilometre.
