The Ohio River Bridges Project in the Louisville-Southern Indiana region of the
United States involves the construction of two bridges across the Ohio River – one in the metropolitan area’s Downtown neighborhood (equipped with mageba bearings), and one eight miles upstream in the area’s growing East End.
With a length of 2,500 feet (762 m), the bridge is just part of the East End Crossing, which has a total length of 8.5 miles (13.67 km).
The overall project is financed by WVB East End Partners, a consortium involving VINCI Concessions, Walsh Investors and Bilfinger Berger PI International Holdings.
TENSA-MODULAR expansion joints of types LR8 and LR11 (with 8 and 11 gaps respectively) are being supplied by mageba USA, to facilitate deck movements at two bridge axes. At each bridge axis, three separate joints are required – one for each carriageway and one for a footway. The LR11 joints can accommodate longitudinal service movements of up to roughly
35 inches (880 mm), as well as transverse and vertical movements and multi-axial rotations.
The joints were designed and fabricated in accordance with AASHTO LRFD Bridge Construction Specifications, and hot-dip galvanized in accordance with ASTM A123.
