The A555 Airport Relief Road remains closed due to flooding.
The dual carriageway remains shut in both directions between the Bramhall Oil Terminal to Styal Road.
Stockport Council say the A555 will stay closed for at least the remainder of today (Thursday).
Photographs taken this afternoon show an abandoned car partly submerged under water on one of the carriageways.
The road closure follows more than 24 hours of torrential rain and flooding across the region in the wake of Storm Christoph.
Around 2,000 homes and businesses in south Manchester were asked to evacuate last night with severe 'danger to life' flood warnings in place for East Didsbury, West Didsbury and Northenden, as heavy snow fell across the region too.
Authorities have been monitoring the River Mersey overnight and now believe water levels to have peaked - but are warning that more rain is forecast over the next couple of days.
Four severe flood warnings remain in place on Thursday morning - two for the River Mersey around Didsbury and Northenden, and two for stretches of the River Bollin to the west of Dunham Massey.
An amber weather warning alert was declared by the Met Office covering Greater Manchester until 12pm on Thursday. An amber alert means 'heavy rainfall is likely to lead to flooding', with forecasters warning of a 'danger to life' due to fast flowing or deep floodwater.
Greater Manchester Police declared a major incident on Tuesday evening due to the storm, with heavy rain expected to batter the region over Wednesday and into Thursday morning.
The A555 was closed yesterday after a number of flood warnings were issued for the region.
The £290m Manchester Airport Eastern Link Road opened in October 2018 and has already proved it is unable to cope with heavy rain.
In April 2019, three million litres of rainfall had to be pumped off the road after a month's worth of rain fell on Manchester in a day.
