Free Cantilever Method Reduces Traffic Disruption
In the district of Miraflores in Lima, Peru, the new Villena Rey twin bridge was recently opened to traffic. The new bridge was built parallel to the existing bridge so the daily rush hour traffic tie ups can be reduced by 40%.
The bridge structure is 114m long, 11.70m wide and consists of reinforced concrete arches that support the bridge deck and hollow box girder. In order to reduce traffic as little as possible, the bridge deck was constructed using the free cantilever method with a form traveller.
To post-tension the bridge deck, DYWIDAG supplied 36 Type 15-0.6" and 19-0.6" DYWIDAG Strand Tendons with MA Anchorages that were post-tensioned using two HOZ 5400 Jacks.
