The article focuses on the repair and maintenance of Heyeswood Railway Bridge in England. In 2000, it was decided to carry out the required permanent strengthening and refurbishment of the bridge in preparation for de-trunking the A556 Northwich by-pass, which was due to take place in April 2002. For analysis purposes the deck structure was idealized as a torsionless three-dimensional grillage. Stiffness and capacities of longitudinal members were based on steel girders acting in a non-composite manner. Primary and main girders comprised four components; top, bottom and vertical members, along with pairs of diagonals to utilize membrane action in the webs.
