Details regarding the 1904 reinforcement project: "...It was therefore decided to renew all the suspension rods, and pins, and to fix steel cables above the suspension links, to supplement them so that the maximum stress in the links due to any possible travelling load should not exceed 5 tons per square inch. It was also decided to build a stiffening girder coupled to the suspension rod on each side of the bridge, and at the same time to widen the bridge by building a footway 6ft. wide outside the suspenders on the north side of the bridge."
