A community petition focused on long-running congestion around the Spit Bridge and Military Rd has drawn attention in Seaforth, where residents rely on the same transport corridor each day.
Overview Of The Issue
Congestion across the Spit Bridge has been a regular issue for decades, affecting travel between Seaforth, Mosman and the northern beaches. The bridge still opens several times daily to allow marine vessels to pass through Middle Harbour, interrupting traffic flow on both approaches.
The petition, published on 17 November 2025, has resurfaced concerns as new housing requirements take effect. These include 500 new dwellings in Mosman by 2029 and 5900 on the northern beaches, which together total 6400 homes.
Transport Concerns Along The A8 Corridor
The petition raises fears that increased population growth will add pressure to the already busy A8 route, which includes Spit Rd, Military Rd and Pittwater Rd. Travel times along the corridor remain slow during peak periods, with long queues forming on both sides of the bridge, including the Seaforth end.
Sources identify several pinch points, including the Warringah Rd and Harbord Rd intersection, contributing to delays that extend along the route toward Seaforth.
Proposals Under Discussion
The petition calls for an assessment of the corridor’s ability to handle additional traffic and seeks planning that addresses both current congestion and expected future demand. Suggestions noted in public discussion include a Metro connection, widening the Spit Bridge and raising its height to prevent marine-related openings.
Community Sentiment
Residents using the Spit Bridge corridor have expressed concern that increased housing density without matching transport upgrades may reduce liveability and affect access to public transport. The petition notes worries about traffic congestion and related impacts on communities along the corridor, including Seaforth.
Next Steps For The Petition
The petition aims to reach 20,000 signatures before it closes on 12 February 2026. The final signature count will determine whether the issue proceeds to formal consideration. Any review would focus on the capacity of the Spit Bridge and Military Rd route, with potential implications for daily travel through Seaforth.
