Distance from center of web (inches or mm) of exterior girder to curbline. (The exterior web of the exterior beam at the deck level, if a box girder.) A negative value indicates the curb line is between the exterior girder and the first interior girder. Used in determining lane fraction for exterior girder. Default is 0.
