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.

[1] The bridge is named after the Scotsman Charles Rawden Maclean, who during his time in South Africa during the Anglo-Zulu War, came to be known as "John Ross".

The original 1959 structure was destroyed during the 1987 South Africa floods causing all coastal road traffic to be redirected to the original steel bridge and one-half of the unused rail bridge, resulting in an estimated increased in road user costs of approximately R40,000 per day.
