Roadworks between Sompting and Shoreham have been extended due to “unforeseen drainage issues”.
The drainage replacement works on a two-mile stretch of the A27 between Sompting and Shoreham will not be complete until February next year. But the extra work will take place at night and there will be no traffic management measures in place during the day.
The Highways Agency (HA) said there had been “drainage issues” it had not been aware of until work began on the site in October.
The HA expects the drainage part of the roadworks to be completed by December 21, with all traffic management removed at that time.
However, workers will need to return to the site in January and February to complete the remaining work to the bollards, lighting and minor resurfacing that is needed.
These works will be carried out overnight and there will be no traffic management measures during the day.
