Reports coming in to the Observer say the A27 Chichester bypass eastbound is closed.
Reports state there is flooding on the A259 at Fishbourne Roundabout and the A259 at Bognor Bridge Roundabout.
The road was closed over night between both roundabouts because of standing water on the carriageway.
However other sources of traffic and travel news say the flood water levels on the road is a ‘changing situation’.
Sussex Police said the A27 from Havant to Fishbourne was closed last night (Monday, December 23) due to floods and no street lights.
