The judgement call
Account-gated at launchExtensive safety testing led to changes allowing the bridge to remain open more often in high winds, improving traffic flow. - The significant cost and disruption associated with replacing critical components like expansion joints on aging infrastructure. - The importance of continuous monitoring and proactive maintenance to extend the operational life of major bridges.
Key engineering challenges
Replacing aging expansion joints on a major motorway bridge. - Implementing changes to allow the bridge to remain open more frequently during high winds. - Managing traffic disruption on the A14 during extensive maintenance. - Addressing structural integrity and longevity of concrete components.
