Suspended Span Underdeck Access Study
Last updated on 18 Oct 2009
The walkways and access system to the underside of the suspended span decks and steelwork located just below deck level was installed in 1983. This system allowed effective safe access for inspection and maintenance, especially painting.
The access system is made up of aluminium boards which span across and are supported by the main structural members of the walkways. These boards are moved from one location to another on the bridge by a combination of manual handling and lifting equipment. Improvements in the procedure over the last few years have made inroads into reducing the manual handling element of the work but it is still significant and in some areas it has to be done in less than ideal conditions.
The boards are deteriorating with age and require more maintenance as they get older. In addition, the capacity of the boards and supports have been recently assessed resulting in some operational restrictions having had to be imposed.
Given the manual handling issues, together with the age and limits on the capacity of the system, the study will look at options for replacement or refurbishment.
