2-21. Bridge Assembly Successive Bay Method. The assembly of a bridge by successive bays is accom-
plished by the consecutive addition of bays along the bridge centerline. When the body of water to be spanned contains
obstacles, has rapidly flowing water (over 6 feet per second), or much floating debris, the successive bay method is the
most effective. The method of deployment and connection depends on environmental factors and should already have
(1) Launch all bridge boats.
(2) Deploy two interior bays (1) and (2) and one ramp bay (3).
(3) Connect two interior bays (1) and (2) (para. 2-20).
(4) Connect ramp bay (3) to interior bay (2) (para. 2-18).
In some cases, depending on the far shore conditions, it may be necessary to deploy two additional interi-
or bays and assemble a five bay raft. This raft can then be used to transport two transporters to far end
shore to be used for anchorages.
(5) Anchor far shore end span to temporary anchorage, holdfast, or natural deadman, (para.2-23), along bridge
It maybe necessary to leave one bridge boat connected to help with grounding far shore end span.
