M. A. Carty Construction Company is favored with luck in the construction of the Lehighton Bridge. It had the good fortune to complete its piers in the Lehigh River before the recent high water affected it. Work on the installing of the steel structure has been commenced. The first girder over the Lehigh Valley Railroad was laid today. A large force of iron workers is employed chiefly from the Bethlehem Steel Company, which is furnishing the steel.
