Road Structures

The Swiss, well-known for their tunnel constructions, have enhanced their reputation with the recent Gotthard Tunnel breakthrough which has created the world's longest tunnel. And in Bern, a roundabout is being re-positioned almost 10m under the ground, which will transform a somewhat dismal road intersection into an attractive gateway to the country's capital. PERI provided a comprehensive formwork solution for the realisation of the massive beams, reinforced concrete slab along with the conically-sh

Geotechnical specialists Bachy Soletanche has started work on a new grade separated interchange on the A41 road in West Bromwich in the English Midlands for a Balfour Beatty/Birse joint venture.

Contractor Ringway has completed work on a tricky project to replace Stile Farm Bridge, which crosses the Great Stour River near Chilham in County Kent, south-east England. Built in the 1920s, the bridge was in a severe state of disrepair resulting in weight restrictions of just 3tonnes. The new structure has a 16m span and is constructed using pre-cast concrete, with pre-stressed steel-reinforced beams based on cast in-situ abutment, and enables the bridge to carry heavier traffic.

The Hungarian government has been investing heavily in extending and improving the country's motorway and trunk road network.

Two Liebherr mobile cranes and four Atlas Copco compressors are playing an important role in upgrades to a highway in Brazilian city São Paolo.

The underslung carriage also permits unobstructed access for site traffic.

Plans are in hand for a new bridge to replace the Gerald Desmond Bridge at the Port of Long Beach in California. The existing structure is not able to cope with anticipated increases in vehicle traffic volumes and is also too low for new generation of cargo ships to pass underneath.
