 Advice:  High level bridge repairs, The Navy Causeway Mangles Bay Rockingham

Mariners are advised that maintenance works are scheduled to commence on the High-Level Bridge at the Navy Causeway, off Point Peron Road, Mangles Bay Rockingham, in late September 2021.

These works will take place Monday to Saturday during daylight hours and are expected to be completed around 31 August 2022.

A floating work platform (6m x 12m) and scaffolding will be used in stages for all works and will be lit by yellow flashing lights. The floating platform will be lifted to perform works to the underside of the bridge. Where the platform is lifted this will reduce clearance to the bridge deck by approximately 3.5m and will also reduce the width of the span by approximately 6m in the location of the work platform. Scaffolding will also be installed on the piers and this will reduce the width of the span by approximately 2m near the bridge deck level to provide access to the scaffold.

Access to the navigation channel will be maintained at all times during these works.

Operators will monitor Marine VHF Channel 16 during operating hours.

Mariners are advised to navigate with caution when transiting the area and stay well clear of the above works at all times.
