Highway Infrastructure Asset Management - Resilient Network Plan

2.1 Definition

Resilience is defined by the Cabinet Office as the 'ability of the community, services, area or infrastructure to detect, prevent, and, if necessary, to withstand, handle and recover from disruptive challenges' and they present a framework of four strategic components for achieving the desired level of resilience:

• resistance - preventing damage
• reliability - operation under a range of conditions
• redundancy - availability of backups or spare capacity
• recovery - enabling a fast response and recovery

The Resilient Network seeks to ensure existing resource is prioritised towards maintaining access and traffic flow on roads identified as being essential to support the social and business needs of both the local and national economy.

2.2 Development of the Resilient Network

The Council has a long established and well-defined Winter Service network, covering 46% of the highway network.  This formed the basis for the development of the Resilient Network, which covers 225km of our network (25%) and considers the following key services and infrastructure:

• main distributer and strategic routes, such as A1046 Portrack Lane
• access to and from Town Centre's and main shopping precincts
• emergency services depots and headquarters, such as North Tees Hospital
• main transport hubs e.g. Railway stations, bus depots
• key infrastructure, such as COMAH sites, National Grid substations, water treatment works, main industrial complexes
• access to outlying communities
• National Highways Strategic Network Diversion Routes
• Tees Valley Key Route Network
• major bus routes
