John Ross Bridge (South Africa)

About

The John Ross Bridge is a steel reinforced concrete bridge spanning the Tugela River, located in KwaZulu-Natal, South Africa. The bridge sits on the R102 regional route from Durban to Richards Bay, crossing the river close to the township of Mandini. The original bridge was completed in 1959 after a fast construction period of just 3 years, but was rebuilt after the 1987 KwaZulu-Natal floods in what is believed to be record time for a structure of its size. The bridge comprises a span of approximately 412.5m and is founded on concrete caissons bored a depth of approximately 18m to the bedrock below the river bed.
