Road-rail bridges are bridges shared by road transport and rail transport. They are sometimes called combined bridges. [1]
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., the Sydney Harbour Bridge). The rail tracks can also be above the roadway, or vice versa (e.g., the Øresund Bridge).
Sometimes, the road and rail share the same carriageway on the bridge (e.g., the 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., the Bechyně Bridge).
"Rail" in this case include all types of rail transport.
A 1930 report listed 33 bridges and estimated that the cost of bridge-keepers, extra maintenance for the decks, etc. amounted to £15,500 a year, as against £4,307 paid to NZR. [43]
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.
During wartime and other emergencies, rail tracks on bridges are sometimes paved to allow road traffic to proceed. Examples include the Ludendorff Bridge at Remagen bridge in Germany.
After a landslide on the Stromeferry road in Scotland in 2012, a 150m section of the parallel railway was paved with rubber tiles to allow road traffic to avoid a 250 km detour. [85]
