Arthur Ravenel Jr. Bridge, United States of America

Project data

Location: Charleston, United States

Design as a cable-stayed bridge, the Arthur Ravenel Bridge utilizes two 175 m high piers at a distance of 472 m from each other, taking the load of the cable stay construction. The bridge which connects Charleston to Mount Pleasant over the Cooper River was steadily constructed in regular weekly cycles using the PERI ACS self-climbing system, lifting four working levels together with the formwork without the use of a crane. Also, VARIO girder wall formwork was used during the 4-year construction project, which resulted in a carriageway height of 61 m and 4 km length. 


  • variable dimensions of the pylon legs of a max. 9.14 m x 7.92 m at the pylon base up to min. 5.47 m x 4.87 m at the top
  • the wall thickness of the pylons changes several times across the whole height
  • short build time
  • high logistical requirements
  • high quality requirements on concrete finish and dimensional accuracy
  • consideration of high wind speeds


Joint Venture:
Tidewater/Skanska USA Inc. and
HBG Constructors Inc./Flatiron Structures Company
