Contractors are to examine the drainage system on the Bexhill-Hastings Link Road after it flooded - just a week after opening to traffic.
The flooding occurred near the Queensway end of the road following heavy rainfall in the days before Christmas and again on Sunday (January 3).
One disgruntled driver said the road, otherwise known as Combe Valley Way, ‘looked more like a canal’ as water encroached onto the carriageway on Sunday.
Others have urged the local authority to take action, fearing the flooding could get worse.
The Environment Agency had issued a flood alert for the ‘Combe catchment’ just after 3.40pm on Sunday.
An East Sussex County Council spokesman said: “We have experienced an issue with standing water during periods of heavy rainfall on a short section of the Link Road around 1km from the Queensway Junction.
“This occurred on one day before Christmas and again on Sunday (January 3).
“The full width of the carriageway was not affected, however, and the road has remained open at all times.
“We have been experiencing very heavy rain in recent weeks and this has affected roads all over the south east.
“However, we have asked our contractors to investigate whether any changes are needed to the drainage system on this section of the Link Road.”
The road opened on December 17 - seven months later than planned and £20m over budget.
Last month East Sussex County Council told the Observer that record levels of rainfall in the months of December 2013, January, February, August and October 2014, was partially to blame.
The local authority said that despite alterations to the programme of work, the weather had an impact on some “key activities” on the site.
