| In the early 1950s modifications were made to create two 3 lane highways between the outer and inner cables. The deck flooring was replaced by a 75 mm. deep concrete filled steel grid. In 1991 the suspenders, cable posts. stays, main cable wrappings were replaced and suspenders adjusted. All of this was done whilst the traffic flowed with only temporary lane closures allowed during non rush hours. In 1999 the deck was replaced by pre-cast steel and concrete panels. |
