A pipeline bridge carrying the Trans-Alaska Pipeline
A pipeline bridge is a bridge for running a pipeline over a river or another obstacle. Pipeline bridges for liquids and gases are, as a rule, only built when it is not possible to run the pipeline on a conventional bridge or under the river. However, as it is more common to run pipelines for centralized heating systems overhead, for this application even small pipeline bridges are common.
Types[]
As there is normally a steady flow in pipelines, they can be designed as suspension bridges.
Walkways[]
A pipeline bridge may be equipped with a walkway for maintenance purposes but, in most cases, this is not open for public access for safety and security reasons.
