2–20. Interior Bay to Interior Bay Connection. When connecting two interior bays the location of the stationary,
or anchored, bay could be in one of several different configurations. The procedures for connecting two interior bays to-
gether will be the same no matter what configuration the bays are in. The bay being connected will always approach from
downstream. All roadway/roadway connectors will be engaged, and all roadway-to-bow ponton travel latches will be
latched. The bridge boat will be secured to bay and will approach connection site from downstream. When connecting
the first two bays one bay must be anchored to shore prior to connection of the second bay.
NOTE
Check bays before connecting to ensure that the lower lockpin is fully retracted. Roadway-to-bow ponton
bridge latches are engaged and roadway/roadway pontons travel latch is rotated down.
WARNING
Extreme caution should be taken when connecting bays. Bays come together with extreme force and
personal injury or death may result.
(1)
Position bay (1) as close to adjoining bay (2) as possible.
(2) Connect lines (ropes) (3) to bay rope cleats (4) and have bridg centerline crew pull bays (1) and (2) together.
(3) Engage roadway/roadway connectors (5).
(4) Have bridge boat keep bay (2) in position.
NOTE
If engagement of lower lockpin is difficult, have bridge boat apply power forward or reverse and use crow-
bar to raise or lower bay as needed.
(5) Position crow bar (6) under roadway (7) and on top of bow ponton (8) and apply downward force to level bays.
(6) Use T wrench (9) and turn lower lockpin (10) clockwise and engage lower lockpin.
(7) Repeat Steps (6) and (7) for remaining lower lockpin (11).
