2019 to 2020
Rehabilitation of the Bridge No 7 included the installation of a temporary hanging access platform, concrete deck removal and replacement with composite wood concrete deck, handrail replacement, cross beam and hanging beams rehabilitation, and concrete sealing of the superstructure.

COMPOSITE DECK INSTALLATION
A composite deck consisting of timber and concrete was installed to limit the weight of the deck.
INSTALLATION OF WATERPROOFING AND WEARING SURFACE
