A closure to a discussion of an article with the aforementioned title, published in this journal (Volume 9, No. 4, July/August 2004), is presented. The closure, by Peter Kocsis, was published in the current issue. The authors of the original paper confirm that they believe that Henry's method and the modified Henry's method include the most dominant factors, employ equal distribution concepts and provide reasonable and reliable distribution factors. Although the discusser recommends a program, SECAN4, for analyzing a bridge for any kind of loading, the authors have no experience with this program. They also agree with the discussers' comments on line load distribution for curbs, railings and sidewalks, but emphasize that their research was on the moment distribution under the AASHTO live load or truck load, rather than on line load distribution.
