The road and rail on these bridges are often on the same level, but segregated, so that rail vehicles could operate at the same time as road vehicles (e.g., Sydney Harbour Bridge). The roadway can also be above the rail tracks, or vice versa (e.g., Øresund Bridge, Oliver Bridge).
Sometimes, the road and rail share the same carriageway on the bridge (e.g., Dom Pedro II Bridge). In these cases, road traffic usually must stop when trains are using the bridge. However, if the bridge is wide enough, both kinds of traffic can operate together as well (e.g., Bechyně Bridge).
"Rail" in this case include all types of rail transport.
Tocumwal – separated by construction of adjacent road-only bridge in 1987.[8]
Murray Bridge[9] from the opening of the railway in 1886 until a separate rail bridge was opened in 1925.

Originally one lane of traffic and the railway shared the area within the truss spans, but a single-lane deck was later attached to either outer side of the trusses to separate road and rail traffic.

On Viti Levu, the CSR Company was obliged to provide road-rail bridges when it built bridges for the Cane Trains to their sugar mills, e.g. the two largest bridges over the Ba and Sigatoka rivers. Many are now rail-only as separate road bridges has been built.
The Ba Bridge (550ft; 170m) in Ba has 19 spans, 17 standard spans (30ft; 9.1m) and a short span at each end, and has been rail-only for many years. The Sigatoka Bridge (810ft; 250m) in Sigatoka has 27 spans. Both bridges are prone to hurricane damage due to extra flow of water; the Ba Bridge often disappears under water, but is not always damaged (see Cane Trains).
Sigatoka Bridge was washed away by storms, January 2009.[24]

The rails are still in place, covered by tarmac. There has been no rail traffic on Numedalsbanen since 1988. The railway is in the road, so car traffic had to stop when trains were passing.
Bruhaug Bridge, also on the Numedal Line, carried both the railway and local car traffic over the river Numedalslågen. The road surface is wood.
Fetsund Bridge, the combined road-rail bridge built in 1919.

Preston Dock Swing Bridge, Lancashire. Road traffic and pedestrians controlled by barriers from the lock control room. Still used by The Ribble Steam Railway and tour trains visiting from the main line, still running in 2012 the bridge is used for delivery of bitumen by railway to the Preston Total Bitumen plant. On arrival from Total's oil refinery in Immingham, North Lincolnshire, the tankers are parked at the exchange sidings. The steam railway staff divide the trains and shunt the tankers into Total Bitumen's siding for the bitumen processing and distribution plant, later reforming the trains for their return journey to Immingham.

Portage Lake Lift Bridge, connecting Hancock and Houghton. The world's heaviest and largest double deck vertical lift bridge. 4-lane road on upper deck, rail on lower deck (converted to trail).

Many Vietnamese mainline railway bridges have small paths or roads (for pedestrians, bikes, mopeds & other small vehicles that can fit) attached to one or both of their sides. Some of these paths are wider, which supports larger & heavier vehicles.
This list covers railway bridges in Vietnam that have these paths fixed on their sides (unless stated otherwise). The list may not cover all existing Vietnamese road-rail bridges & may not update future changes to the bridges listed below.
