Most days, it would take you less than 30 minutes to get from King's Lynn to Hunstanton.

But last night drivers took hours to travel the 20 miles or so as the coast road ground to a standstill.

Traffic was queued from Lynn back along Hunstanton's Cromer Road, past the Glebe House School, with drivers reduced to a crawl.

Earlier, unseasonal warm weather brought sunseekers flocking to the coast in droves.

But as the mercury topped 20C and the car parks filled up at Holkham and Wells, it was only ever going to have one outcome, when all the day trippers headed for home.

By the early evening, @suffolknorfolktravel reported that there were 'severe delays' on the A149 at Hunstanton and Castle Rising, on the outskirts of Lynn.

A few miles away on the Dersingham by-pass, where the limit is 60mph, speeds were down to 10mph. Jams lasted well into the evening.
