Queen Victoria Hospital in East Grinstead has warned patients to allow extra time when travelling to the hospital.
Some temporary traffic lights at the Blackwell Hollow roundabout are causing significant delays and in some instances patients have been late or have missed appointments.
While it is hoped that the works on Holtye Road will be completed today, works will continue on Blackwell Farm Road until next Monday 20th March. Traffic is particularly congested around rush hour.
