Abstract:
A method of enlarging the space beneath a masonry arch bridge which includes a masonry arch and a spandrel wall at each end of the masonry arch includes forming a movable portion of the masonry arch bridge by cutting the spandrel walls to form a cut on each side of the masonry arch. A lifting force is applied to the masonry arch to raise the masonry arch to a raised position. The masonry arch is then secured in the raised position.
