Drivers are being informed of the re-opening of lanes 2 and 3 on the A14 Eastbound carriageway near Newmarket.
National Highways has been continually working on the eastbound A14 between junction 37 (Newmarket) and junction 38 (Red Lodge) since last week.
Teams are working 24 hours a day and making every effort to clear the flooding caused by high groundwater levels.
Over 12 million litres of water have been extracted since last week, roughly equivalent to five Olympic-sized swimming pools.
National Highways is working with partners, including the Environment Agency, to resolve the issue.
Following the full closure last night and the reopening of lanes 2 and 3 this morning, a speed limit restriction of 40 mph is in effect.
Speeds through the lane restriction will be monitored, and action will be taken for non-compliance with the speed limit.
The work accomplished overnight includes the successful completion of the construction of the pipeline network, specifically designed to prevent flooding from the site to the outfall.
After addressing minor leaks, both the pumps and the pipeline network are functioning seamlessly as expected, actively engaged in the pumping process from the flood location to the outfall site.
Lane 2 has been thoroughly swept and treated, guaranteeing safe traffic flow.
National Highways’ regional director, Martin Fellows, said: “We apologise for the inconvenience caused to drivers and local communities.
“The team is making every effort to re-open all lanes as soon as possible.
“This flooding issue continues to be a regional priority, and we are seeking assistance from all parties.
“Our roads keep the country moving, keep families connected and businesses in business, so our roadworkers are vital to everyone’s wellbeing, and their wellbeing is vital to us.”
With the source of the flooding believed to be from high water levels in the area, it could be some time before the water recedes and National Highways is urging drivers to avoid the area if possible.
A spokesperson for the Environment Agency said: “We are currently working with partners at National Highways around the flooding issues on the A14 at Newmarket.
“Following the exceptional rainfall in the area over the last few months, the ground is very saturated and groundwater levels are high.
“We currently have a groundwater flood alert in force for areas of Newmarket.”
