County councillor for the area, Chris Dowling, said the scheme had been put off for a number of months.
The news came in a written report from Cllr Dowling to Uckfield Town Council, which was read at a meeting by the mayor, Cllr John Carvey.
He said the county was continuing to discuss the issue with Linden Homes, developers of the new housing estate off Eastbourne Road.
Cllr Carvey commented: “It is not the county that has delayed the New Road measures; it is the developer.”
At one time it was thought the work would be completed early in 2012 and then would have started in January this year.
