Temporary Concrete Barrier Crossing Expansion Joints

State IL
Description Text

Please see the attached photo of an inverted U shape connector placed over a TCB at a bridge expansion joint.  The device is bolted to the top of the barrier on one side and free to slide on the other.

Apparent concern is for transfer of tension across the joint.  Does this present a pocketing potential? 

We are pursuing changing this to overlapped runs of TCB, about 100' overlap total.  However, width will preclude achieving 2' separation of the two runs.  So either method leaves some concern.

Any comments and suggestions would be welcomed.
