The work on the A484 Fabian Way between Jersey Marine at the Amazon Roundabout and the M4 slip road will begin on Monday 30 June but is not expected to be complete until Monday 8 December – some 23 weeks later.
Traffic management, including lane closures are to be in place 24/7 for the duration of the scheme.
Neath Port Talbot Council say the work is to address persistent flooding issues that regularly affect the eastbound carriageway, cycle path and laybys during periods of heavy rainfall.
Funding for the work has come from The Welsh Government’s Resilient Road Fund.
A council spokesperson said: “Thank you for your patience while we carry out these critical drainage improvements. Once a contractor has been appointed further details will be released and updates will be provided as works are progressing.”
Firstly they must have appointed contractors because they’ve already given the dates for the works to be completed. Also, for a tourist based season especially Swansea what a time for repairs !!!! Another NPTCBC right royal cock up
