Huge delays and four miles of congestion remain on the A14 due to lane closures caused by flooding.
National Highways shut the eastbound carriageway, between Newmarket and Kentford, on Wednesday evening as a result of heavy flooding which has remained for more than a week.
Although one lane was reopened by Thursday afternoon, long delays remain in the area.
A spokesman for National Highways said there is currently four miles of congestion in the area.
The authority has advised drivers to avoid the area - and the carriageway could be shut once more, with further rain forecast.
Simon Amor, head of scheme delivery said: “We apologise for the inconvenience caused to local communities. The team is making every effort to remove the standing water in all lanes. However, they are facing challenges as the water continues to return after removal. We urge drivers to avoid the area, if possible.”
“Lane three is now re-open, but there's a chance we might need to close it again if heavy rain is expected.”
