Flooding on the A23 Brighton Road south of Crawley caused two lanes to be closed this morning (November 7).
There was queueing traffic in the northbound carriageway at Handcross to Pease Pottage due to water flooding the road.
There has also reportedly been an accident in this area, at about 7am.
Almost 30 minute delays were expected.
