Beam guard bolt through box culvert deck option

Question
State WI
Description Text

In TRP-03-114-02 you used a bottom washer plate to bolt through.


Instead of using this washer plate can square plate washers be used?


Can this detail modified to accept MGS mounting heights?

(active) 		There should not be any issues with using square plate washers.  It is recommended to utilize the same thickness, 1/4"

Yes, raising the rail height to 31" has been allowed.  The post should be extended with all other dimensions (base plate, weld, bolts, soil fill, and half post spacing) remaining the same.
