Motorists ground to a halt after almost a foot of water flooded the road at Broughton.
Traffic was forced to wait in queues for 25 minutes yesterday lunchtime as vehicles drove through the deluge one by one.
The water stretched across both sides of the carriageway on Garstang Road, on the Fulwood side of Broughton traffic lights, and onto nearby driveways.
John Flynn was on his way from Garstang to start his shift at Broughton Printers when he was delayed by the flood.
He said: “There was traffic queueing back to Barton Grange Hotel.
“The journey only normally takes me about five minutes but I was waiting for about 25.
“The water was about half way up the wheels so the cars could only really go through safely one at a time.
“I’d say it was 50 or 60 yards from one end to the other.”
One local resident said that he put the flood down to heavy rain during the night.
He said: “It’s really quite bad - probably about 10 inches deep and right up onto some of the driveways. It’s been like that all morning.
“I can’t see anyone putting things right so maybe it’s just down to the rain.”
John Gatheral, principal highways engineer at the county council, said: “There are signs on either side of the road to provide motorists with advance warning of the flooding.
“This road is prone to flooding following extreme weather and we are working with a local resident to provide protection to his property.
“We are due to carry out investigations later this month to establish the condition of the surface water pipe beneath and next to the road. We are also looking at measures that will minimise flood risk in the future.”
This week’s dismal weather is forecast to take a short break this weekend. A Met Office spokesman said Saturday would provide a brief respite from the rain, with generally bright, dry conditions.
