Slope check
(1)
Longitudinal. Ensure that the difference in elevation between the F’ (use elevation of RB) and F peg
does not exceed 1/lo th of the total bridge length. If it does, it will be necessary to crib up, undertake a major construction
project, or find another centerline.
(2)
Transverse/cross. Ensure that the transverse slope on both banks does not exceed 1/10th of the bridge
width (4.0 m) for MLC 60 and below and 1/20 th of the bridge width (4.0 m) for MLC 61 and over. No transverse slope is
permitted for MLC 100(W).
