Ohio River Bridge - East End Crossing, OH

Project data

Location: Louisville, United States

  • The East End Bridge over the Ohio River is a cable stay bridge that consists of two 300’ tall “portal” shaped pylons.
  • It will have a total length of 8.5 miles when all work is complete, with 1200 workers including subcontractors involved in the construction.
  • The total length of the main span across the Ohio River is 2500 ft, with 104 stay cables weighing in at 1000 tons. 
  • The project requires 24,000 cubic yards of structural concrete and almost 6700 tons of structural steel. 

Requirements

  • Special requirements that need to be met include a Class A Concrete Finish as well as pour pressures up to 2000 psf (95 kN/m2). 
  • For the lower legs, PERI designed a custom material- and cycle time-saving “Leap Frog” formwork solution with custom VARIOKIT trusses and VARIO formwork, where forms and platforms leap from segment to segment.
  • The roadway strut top slab is formed with MULTIFLEX, while the 15 segments of upper legs are climbed with ACS hydraulic climbing devices.
  • Access to the towers is achieved by VARIOKIT access platforms and PERI UP stairs. 
  • Additional challenges were presented by a hundred year flood requiring the access system to be redesigned; day and night crews are ensuring steady progress of the project.
