Unlucky drivers on a stretch of road in East Anglia are caught up in some of the worst traffic jams in the country, it has been revealed.
The A428 has officially been named the least reliable major road in England.
The stretch of road takes motorists between the A1 and the M11 near Cambridge.
Between May 2010 and April 2011 just 34.8% of journeys taken on the A428 were on time, according to the Department for Transport.
During the same period, only 38.9% of journeys on the reverse route from the A1 near St Neots in Cambridgeshire to the M11 north west of Cambridge were on time.
The only thing that drivers using the troublesome stretch of road can rely on is theircar insurance.
The A428 proved even worse than the often-jammed M25, where the section between junction 16 near Uxbridge in west London and junction 23 at South Mimms in Hertfordshire was the third-worst road, with only 43.7% of journeys on time.
The most reliable stretch of road managed by the Highways Agency in the 12 months ending in April was the M4 between Wales and junction 15 south of Swindon in Wiltshire.
A total of 93.4% of journeys on the west-bound, Wales-heading stretch of this section of motorway were on time, while the on-time figure for reverse journeys was 92.5%.
