The East of England's combined pothole problem drills down almost three kilometres deep, which is almost 17 times the depth of the English Channel (174m), a new study has found.
Motorists are now able to visualise the true depth of pothole problem by region and local authority areas across the UK thanks to Confused.com.
In Norfolk, 6,365 potholes were reported last year with £1.3m spent on repairs and £40,379 on compensation.
The regional view reveals that Hertfordshire has the deepest pothole problem in the East of England, with a total depth of 1,112m.
In 2016, councils in the East of England forked out more than £15m to repair potholes and more than £232,000 in compensation to motorists who have had their car damaged by craters in the road.
The total depth of the UK's potholes combined is more than 40km deep – almost four times the depth of the Pacific Ocean.
As the cold weather starts to set in, more and more potholes may start to appear on roads – a dreaded issue for both drivers and local councils.
Confused.com, a financial services comparison website, reported that a third of motorists in the UK said their car has been damaged by a pothole.
The research, which was conducted following freedom of information requests, reveals a total of 62,027 potholes were reported to the region's councils in 2016.
Each local authority was asked for the minimum depth of a road defect to be considered a pothole, and this figure was aggregated against the total number to reveal a depth of almost 3km (2,957m).
Amanda Stretton, motoring editor at Confused.com, said: 'Scrolling to depths of more than 40km really puts into perspective just how deep the UK's pothole problem really is.
'They are a major bugbear among drivers, not least because of the damage they do to our vehicles – around £3.1 million worth of damage, which has been paid out by almost half of the UK's councils.
'If drivers experience a bump in the road, they should report it to their local council as soon as possible before the problem gets any worse.
'The cost of motoring alone is getting more and more expensive and damage repairs is a big contributor to this, as car parts increase in price as well.'
