Two layer diagonal decking for wooden bridges

Abstract

A deck for wooden bridges that consists of two layers ( 3 & 4 ) attached to bridge structural members ( 1 A & 1 B, 2 ) using traditional attachment methods ( 5 ). Having the first layer fastened to bridge support members in an oblique angle. With the second layer on top of the first layer and attached through first layer to bridge support members in the opposite oblique angle from the first layer.

1 . A method of decking wooden bridges for pedestrian and vehicular use that substantially increases lateral strength, and therefore overall strength, comprising: 
 (a) a first layer of decking fastened to bridge support members in an oblique angle to said bridge support members,    (b) a second layer of decking installed on top of said first layer in an opposite oblique angle to said first layer and fastened through said first layer to said bridge support members, whereby substantially increasing lateral strength of said bridge, hence rendering entire said bridge stronger and more resistant to catastrophic failure, such as, but not limited to those caused by flood, wind, earthquake.
