The 50-year-old Tees Viaduct on the A19, spanning the River Tees and surrounding infrastructure, has undergone a sustainable refurbishment to extend its lifespan while maintaining full traffic flow. Chronic chloride ingress had caused significant concrete deterioration, threatening the reinforced concrete piers and superstructure.
Rather than demolition, innovative techniques including impressed current cathodic protection (ICCP) and modern concrete repair methods were used to arrest corrosion and restore structural integrity.
The project exemplifies the application of PAS 2080 carbon management principles, demonstrating how collaboration, sustainable construction, and advanced engineering solutions can protect critical transport infrastructure while minimising environmental impact and disruption.
