Major: road or rail bridges of any width, with one or more in-channel supports, OR wide bridges with bank abutments extending along >=25m of bank-length. Banks are often modified immediately upstream and downstream of a major bridge. Photographs are essential for interpretation of potential impacts of the in-channel supports.
Major bridge
Intermediate: road or rail bridges without any in-river supports, and with bank abutments occupying 10- 25m of the bank.
Intermediate bridge
Minor: all road/rail bridges lacking in-river supports, and with bank abutments occupying <10m of the bank. Also includes all bridges, irrespective of width, with no abutments on the bank, such as viaducts.
