Stonehenge tunnel contract

A contractor is now being sought for the UK’s Stonehenge Tunnel project. The work involves building a new tunnel and new stretch of dual carriageway, moving the busy A303 route away from the Stonehenge monument.

The project is expected to cost €2 billion. The tunnelling conditions are poor as the rock has a poor strength and is faulted, while the water table is high. This tunnel will require extensive reinforcement as well as effective water protection and drainage measures, which also meet tough environmental requirements.

The tunnel stretches will be around 3.2km in length. Construction is planned to commence in 2021. The project is controversial however as some critics suggest it could cause damage to important archeological sites around Stonehenge.

The project is considered a priority for the UK’s transport network as the A303 carries heavy traffic and the current two lane section near to Stonehenge suffers heavy congestion. However previous plans to build the Stonehenge Tunnel Bypass have been halted and until work actually commences, this latest project may still face being cancelled at late notice.

    A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

    Preserving the unspoiled Mullum Mullum Valley was the major consideration when deciding to build a traffic tunnel The answer to one of the major issues facing construction of the A$2.5 billion EastLink route in Australia was simple: construct a tunnel. While it was expensive, those involved realised they had little option but to go underground to protect the environmentally sensitive Mullum Mullum Valley, an untouched area of wood and bushland in Melbourne.
