Corrections Summer 2012 On page 29 of the Summer issue, the forces and coeffcients of friction were incorrectly stat- ed. In the right column, the second sentence of the second full paragraph should read, "The initial push required a total force of approxi- mately 230 kips corresponding to 12% friction, and approximately 115 kips corresponding to 6% friction to continue moving the bridge." Fall 2012 On page 60 of the Fall issue, the incorrect editor's note was published. The editor's note should read, "If you would like to have a specifc provision of the AASHTO LRFD Bridge Design Specifcations explained in this series of articles, please contact us at www.aspirebridge. org." On page 30 of the Fall issue, the stay-cable and post-tensioning/form traveler suppliers were inadvertently left off the profle listing. The stay-cable supplier was Tensacciai SpA of Italy, and the post-tensioning/form traveler supplier was Schwager Davis Inc., San Jose, Calif. We regret these errors.
