BRIDGE PROJECTS

 

 

Bosphorus Bridge, Turkey

 

The Bosphorus separates the European and the Asian continent. As part of the new Northern Marmara Motorway' highway, the third bridge over the Bosphorus is realized.

The world's widest bridge as combined cable-stayed suspension bridge was built by order of the Turkish government during the years 2013-2016. more

 

Hardanger bridge, Norway

 

The Hardanger bridge which is located in the south west of Norway is a new built suspension bridge with a length of 1310 m.

The bridge consists of 23 elements with 380 tons which were produced on land and then loaded onto a transport ship. more

 

Slide in of a deck over the existing arch in Montreux, Switzerland

 

The slide-in of a new concrete deck at the Swiss Simplon railway line was realised during a just two days lasting rail traffic interruption.

In order not to stress the existing vault by eccentric loads, the new deck was slid on an entirely independent temporary steel structure before being lowered in final position. more

 

Oakland Bay Bridge Demolition in San Francisco, USA

 

In collaboration with Freyssinet USA, Hebetec Engineering lowered 5 bridge trusses during demolition works of the Okaland Bay Bridge at San Francisco Bay.

The lowering onto barges from heights of about 42 to 50m was carried out by using 8 type H-600 strand jacks. more

 

Guying of the Odertal Bridge, Germany

 

During the construction of the Ordetal bridge a certain part of the terrain was not allowed to be strained by auxiliary constructions, because of environmental reasons.

Therefore 1'030 tons of steel structure was assembled by using the free cantilever method. more

 

Dismantling old Port Mann Bridge Vancouver, Canada

 

With the expansion of the British Columbia Highways, a new cable-stayed bridge over the Fraser River in Vancouver was built during the years 2009-2012. Due to this fact, the 50 years old Portman Bridge could be dismantled.

By means of auxiliary steel constructions, the steel structure was dismantled with strand jacks and lowered 40 meters partly. more

 

Puente El Carrizo, Mexico

 

In the Mexican state of Sinoa, bordering the Pacific Ocean, numerous bridges and tunnels for the new construction of the Durango-Mazatlan highway were built.

For one of the bridges, the PEC bridge, Freyssinet Mexico together with Hebetec lifted multiple bridge segments to approximately 200 meters above ground. more

 

Forth Replacement Crossing / Queensferry Crossing Bridge

 

Six traveller steel frames are being used to lift bridge decks from barges into position at the construction of the world wide longest three-tower cable-stayed bridge over the Firth of Forth in Scotland.

Hebetec provided independently working strand jack- and hydraulic systems and control units for the liftings and traveller moving. more

 

Lowering, sliding SBB bridge on the A2 in Bellinzona, Switzerland

 

The operation formed part of the AltTransit project to build a New Railway Link through the Alps (NRLA). Significant modernisation work is underway to prepare for the high-speed line, with the aim of improving public transport and transferring as much goods traffic as possible from road to rail.

Hebetec was therefore called in to slide the Cavalcavia Bridge, which lies on the path of the future railway line. more

 

Lifting of bridge segments Ulyanovsk, Russia

 

Hebetec received the assignment to lift five bridge segments into final position for the completion of the Volga Bridge at Ulyanovsk in Russia

The segments were transported by barges to the bridge piers. In reason of the spans length being larger than the distance between the piers the lifting took place offset. more
