Canyon Bridge Rehab - Work Progressing on Upstream
Truss
Jeffersonville, July 29, 2004 - With the repairs completed on the south, or
downstream truss, and the truss returned to the abutments, work began on the upstream
truss.
The plans call for the replacement of both end posts;
the diagonals in the end panels at each end; the inside arch member at the east end; the inside top
and bottom lower chord-end sections at both ends of the truss; and the inside bottom middle
lower chord-section.
Unplanned was the replacement of the kingpost in the
third panel from the east end, found to be rotted.
