Transport bosses say the full opening of the Manchester Airport Relief Road has been delayed - blaming too much rain.
The £300 million bypass, which runs from the A6 in Hazel Grove to the M56 via the existing A555 in Bramhall, was scheduled to be fully open in November.
But this date was pushed back to early 2018, and after further complications caused by the British weather, is now said to be spring next year.
It is the latest twist in a long-running saga that saw the three councils involved, Stockport, Manchester and Cheshire East, approve plans for the road in early 2014.
Other problems the road has faced are a public inquiry and more recently potential danger from golf balls at the sixth hole. The possibility balls could hit cars on the link between the A6 and the bypass meant a planning application for giant protective nets needed planning permission before work could continue.
The first section of the relief road will be opened to traffic after Easter.
A section between Yew Tree Avenue and Norbury Hollow Road, in Hazel Grove, will be used while construction work on the A6 bus bridge takes place.
The existing A6 will still be open to pedestrians and cyclists and access to homes and businesses maintained.
