Abstract

Periods of heavy prolonged rainfall occurred in most parts of England between September and November 2000. A particularly severe storm affected many parts of the country on 29/30 October 2000 and heavy rainfall also continued in the north-east of England during the first week of November. These storms resulted in a considerable number of temporary lane or road closures on all types of roads including those operated by the Highways Agency (HA). Some of the incidents on the HA Network were caused by fallen trees and high winds but the great majority were due either to drainage systems being overloaded or to surface flooding from rivers or other watercourses. This study was commissioned in December 2000 by the Quality Services, Traffic Safety and Environment Division of the HA to review the performance of the Network during the storms of Autumn 2000 and identify improvements that would improve its resilience to adverse weather conditions in the future.
