2-26. Bridge Recovery.
a. General. Disassembly procedures of the ribbon bays are generally reverse of the assembly procedures. Either
the successive bay method of disassembly along the bridge line or swinging of the bridge upstream prior to disassembly
may be used.
b. Disassembly By Successive Bay Method
In the successive bay method, a bay-to-bay connection must first be
opened near either shore (depending on where the retrieval equipment is available) and the shoreward bays pulled up
onshore approximately 5 ft (15 m). This creates the space required to maneuver the first by after adjacent bay disconnec-
tion has been performed.

Unlatch roadway connector (1).
Retract approach ramps (2).
Open hydraulic pump access covers (3), set pump control levers (4) to PUMP, open vent valves (5) and oper-
ate pumps using handles (6) to relieve grounding. Close vent valves (5), set control lever (4) to TRAFFIC
and close pump access covers (3).
Install T wrench (7) on lower lockpin screw (8) and turn counterclockwise to retract lower lockpin.
Repeat Step (4) for remaining lower lockpin.
Have anchorage crew pull shoreward bays partially on shore and adjust anchorage as needed.
