BRIDGE RECOVERY, SWINGING BRIDGE METHOD
In the swinging bridge method, the bridge assembly is swung upstream from the
bridge line to the shore to allow disassembly along or near the shore where the
current is slower than in the main flow of river. This makes bay-to-bay removal
All bridge personnel must wear approved life jackets
while on the bridge. Failure to comply may result in
injury or death to personnel.
Exercise caution when walking near centerline of
roadway; the ponton alignment lugs project above the
roadway surface on interior bays and constitute a
tripping hazard. Failure to comply may result in injury
Ensure roadway surface is free of rocks, mud, and
debris prior to bridge recovery. (Refer to WP 0053 00.)
a. Open both pump access covers (3), move pump control valve levers (1) to UP
position, and raise ramp bay (2) enough to relieve grounding. Close access
Never swing bridge assembly downstream; always
swing bridge assembly upstream to far shore.
b. Have appropriate number of bridge boats connected to bridge assembly for
anchorage. (Refer to WP 0036 00, table 4.)
c. Remove anchorage from near shore ramp bay (2), swing bridge upstream
while anchorage crew adjusts anchorage at far shore as needed.
d. Anchorage crew will temporarily anchor bridge assembly to far shore.
Start disassembly from downstream end of bridge.
e. Have boat secured to bay being removed.
