The bridge showed signs of problems within 12 months and the contractors were called back to repair some faults with the piers. Through the 1920s and 1930s, many design faults and problems became evident. By 1925 the original loading of the bridge was considered inadequate and in 1925 it was decided to strengthen the deck. The work took nearly six years between 1926–31 and numerous problems were experienced with the pin-jointed construction of the trusses, which while easy to assemble were difficult to maintain and strengthen.
