Stonehenge tunnel project being designed

Consultant AECOM is now working with Highways England on improvements to the busy A303 in the UK. The road upgrades will be carried out between Amesbury and Berwick South Down along a 13km section of the A303 route. AECOM will work with its supply chain partners Mace and Mouchel on the project. As the current alignment for the A303 passes just 165m from the Stonehenge World Heritage site (WHS), there is a strong need to redevelop the route so that it causes less harm to this important archaeological area.

Consultant 1397 AECOM is now working with 8100 Highways England on improvements to the busy A303 in the UK. The road upgrades will be carried out between Amesbury and Berwick South Down along a 13km section of the A303 route. AECOM will work with its supply chain partners Mace and Mouchel on the project. As the current alignment for the A303 passes just 165m from the Stonehenge World Heritage site (WHS), there is a strong need to redevelop the route so that it causes less harm to this important archaeological area. The A303 features a single lane in either direction at this stretch, which is not able to cope with traffic demand. Delays are frequent along this stretch of the route at peak periods, particularly during the holiday season when the normal traffic volumes, which includes a high percentage of heavy trucks, are further augmented by the presence of tourist vehicles. Safety is also a key concern. As a result, the plans call for the construction of a dual carriageway route running through a tunnel, which will boost capacity and safety, while minimising the impact of the busy road on the important archaeology of the area. The route also currently passes through Winterbourne Stoke and the project includes a bypass for the village, as well as improvements to existing junctions between the A303 and the intersecting A345 and A360. As technical partner, AECOM will support Highways England in the delivery of the project, providing highways and tunnelling design services, as well as environmental, heritage, noise, traffic modelling and procurement consultancy services.

    Rebuilding a congested stretch of highway in Florida will cut congestion and boost safety for commuters - Mike Woof writes. Florida’s 214km-long I-4 highway provides a key transport route between Tampa and Daytona Beach, but has an unenviable reputation for both congestion and safety, with frequent delays due to heavy traffic as well as crashes. The stretch running through the city of Orlando is particularly prone to jams at peak periods, with huge traffic volumes resulting in vehicles having to slow to a c

    The Highways Agency in the UK has appointed a joint venture between Mott MacDonald and Grontmij to analyse various options for upgrades to the A27 Chichester Bypass. The aim of this project is to improve traffic flow and relieve congestion. The bypass is a 5km dual carriageway with five roundabouts and one signal control junction. It provides a key east-west transport link along the south coast of England. This connects Brighton, Worthing, Chichester, Portsmouth, Southampton. It currently suffers from heavy

    Construction work is to restart on a new tunnel project in the South German town of Garmisch-Partenkirchen following the necessary approvals having been received. The town lies to the south of Munich and is a popular winter ski resort, while in summer it also experiences heavy tourist traffic as it lies on a key route between Germany and Austria, as well as Italy, lying to the south. The busy Autobahn 95 connects Munich’s southern side with Garmisch-Partenkirchen. But this route ends just to the northern si

  • Expressways upgrades for key UK routes
    December 15, 2017
    Key routes in England are to be upgraded as part of a programme of works worth a mighty €33.9 billion (£30 billion) plan from 2020 to 2025. This five year plan from Highways England will see many of the major A road routes being reclassified as A(M) expressways. These will resemble motorways in many respects, with new on and off ramps and additional lanes being constructed. The A14 stretch between Cambridge and Huntingdon will be one of the first stretches to be upgraded in such a fashion. This is an
