This closure marks the start of the final phase of the new vehicle bridge construction and  includes earthworks and asphalting the new bridge tie-ins with Allawah Road East and West, line marking, replacing curb and channelling, and installing new streetlights and signage.

The works are expected to take around six weeks and, once complete, the new two-lane vehicle bridge will open to traffic. The weir bridge will remain closed for repair and maintenance works, and open to pedestrians and bike riders at a later date.

The alternate route during this closure is via Colleges Crossing on Mount Crosby Road. The project team is aware that during low-level flooding at Colleges Crossing, the Mount Crosby Weir Bridge becomes an access point for the community. If there is a wet weather event or an emergency during the closure period and Colleges Crossing becomes unavailable, the weir bridge can reopen to traffic at short notice. 

Expected traffic impacts

• Mount Crosby Weir Bridge closure to all traffic from 16 February 2024 (subject to weather). The alternate route for approximately six weeks is via Colleges Crossing on Mount Crosby Road.
• Heavy vehicles will access the Mount Crosby new vehicle bridge worksite from Mount Crosby Road and Allawah Road East between 6:30am to 6:30pm Monday to Friday, and 6:30am to 4:30pm Saturday. 

Expected construction impacts

• Construction activity associated with road surfacing and services connection including steel works, sawing, and heavy vehicle movements between 6:30am to 6:30pm Monday to Friday, and 6:30am to 4:30pm Saturday.  
• Nearby residents and businesses may experience temporary noise impacts as well as low levels of vibration and dust.
• Reversing beepers and flashing lights on construction vehicles will be used as this is a safety requirement.

This work may need to be paused and/or rescheduled in the event of bad weather. Every effort will be made to minimise impacts on the local community and environment while this work is undertaken. Seqwater and BMD Constructions thank the community in advance for your patience and understanding while these works are carried out.
