Rethe lifting bridge, Germany


After the construction of the currently largest double bascule bridge in Europe in 2016, the old lifting bridge had to make room.
Hebetec received the order to lower the counterweights of the Rethe lifting bridge from 60m so that they could be dismantled at ground level and recycled. The bridge itself had already been dismantled. more


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.

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.

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.
