Waterproofing and resurfacing

Overview

For the first time in the Sydney Harbour Bridge 80 year history the bridge road surface was stripped back to the original concrete deck to carry out essential maintenance. The benefits of the resurfacing and waterproofing include:

  • Creating a smoother and more durable road surface.
  • Reducing road noise as the new surface will be smoother and quieter than the current one.
  • Reducing the risk of corrosion and structural damage on the bridge deck.
  • Rejuvenating the bridge which will be 80 years old on 19 March 2012.

Waterproofing the bridge deck has minimised the need for future repairs. The work extends from Fitzroy Street in the north to Cumberland Street in the south. This work is especially important on the southern and northern approaches to the bridge. A new epoxy waterproofing material has been applied, in part by hand, to maximise the waterproofing process.

The project went smoothly, in spite of wet weather. The bridge was able to be opened 10 hours ahead of schedule on Sunday 22 January 2012.
