The Bill Emerson Memorial Bridge is a cable-stayed bridge connecting Missouri’s Route 34 and Route 74 with Illinois Route 146 across the Mississippi River between Cape Girardeau, Missouri and East Cape Girardeau, Illinois.
The project consisted on the rehabilitation the West approach, on the Missouri side of the bridge, by replacing the approach slab, repairing the back wall of the abutment and exchanging the modular expansion joints.
mageba supplied two TENSA®MODULAR LR8 modular expansion joints to replace the existing 15 year old modular joints at the Missouri abutment, for East and West bound traffic.
The rehabilitation project required the new joints to have 8-gaps for a new capacity of 24 inches (609 mm) of longitudinal movement compared to the existing 6-gaps, of only 18” (457 mm) of movement.
In addition, mageba supplied the barrier cover plates at the parapets and provided on-site installation supervision.
