Heavy rain and a bank holiday resulted in the delay to roadworks on the A143 between Wortham and Botesdale last month, according to Suffolk County Council.
Resurfacing work has finished to strengthen the road after it was laid with a 60mm layer of asphalt. It is the first of a two part process, with surface dressing set to applied for two nights around July 22.
A board warned motorists the road was to be close for four nights from May 20, but the road was not opened fully again until May 29, and the notice not amended with the revised date.
A spokesperson for Suffolk County Council told the Diss Express: “The current road surface is in a temporary condition. It is open to traffic although a 30mph speed restriction is in place for the safety of the public pending the surface dressing.
“Further temporary traffic management measures will be used when the dressing takes place.
“The notice boards did advise that the strengthening works would take place over 4 nights as from May 20 but regrettably two nights were lost due to heavy rain.
“Thus they were completed in the early hours of May 29, allowing for the bank holiday weekend.”
