Even if it is common, it probably would not meet...

This is even sometimes done for barrier, but they are typically divided equally between...

    LRFD Lever Rule

    I compute a separate LLDF (live load distribution factor) for the truck wheels and the lane load. I draw a triangle with the peak of the traingle at 1 at the suspect girder and going to 0 at adjacent girders (or remaining at 1 if an overhang is adjacent). I then compute the ordinate on this...

The applicable code is AASHTO LRFD Bridge Design Specicfications. Of particular interest is the load combinations...
