Austroads has published a report with information about the design, construction and maintenance of 122 road tunnels in Europe, Asia, North and Central America, Australia and New Zealand.
The project was designed to assemble information on the construction and operation of a large number of recently completed road tunnels from across the world. With this information it was proposed that standards applicable to road tunnel construction in Australasia be reviewed to reduce the costs of designing, building and operating Australasian road tunnels.
A considerable data searching process was undertaken during this project, with a number of sources of information utilised, including a literature review of printed and on-line media, consultation with industry experts and industry bodies and a survey issued to tunnel operators.
The project was not able to obtain a high level of quality tunnel information which could be used to identify best practices, however, a large number of tunnels were identified for which at least partial information was obtained on the targeted attributes to be collected.
