Changing Traffic Conditions Reported on Sydney’s M5 Motorway Due to Westbound Upgrade Works

SYDNEY, New South Wales — Motorists traveling along Sydney’s M5 Motorway are experiencing altered traffic conditions and localized delays on Monday, September 28, 2026, as major construction activities proceed along the M5 Westbound corridor in South-West Sydney.

Transport for NSW and road safety officials confirmed that no major motor vehicle collisions or emergency incidents have been identified in connection with current delays along the corridor. Emergency services remain on standard monitoring status across the network, and drivers are advised that current travel disruptions are strictly linked to planned infrastructure works.

Official Status and Traffic Management

Transport for NSW and head contractor Seymour Whyte are executing ongoing day and night construction work along the M5 Westbound corridor between Heathcote Road in Moorebank and the Hume Highway in Casula.

The $380 million jointly funded upgrade includes constructing a new three-lane bridge over the Georges River, the Southern Sydney Freight Line, and local rail corridors, as well as eliminating existing weave points between Moorebank Avenue entry ramps and the Hume Highway exit ramps. Traffic controllers have implemented temporary lane shifts, reduced speed limits, and intermittent ramp closures across the zone. Authorities advise motorists to allow extra travel time through Liverpool, Casula, and Moorebank, follow electronic Variable Message Signs (VMS), and consult Live Traffic NSW for real-time updates.

Community Guidance and Project Scope

The M5 Westbound Upgrade aims to improve long-term road safety, freight access to the Moorebank Intermodal Terminal, and network connections across western Sydney.

Local commuters, transport operators, and residents in surrounding suburbs are urged to exercise extra caution when traveling through active work zones. Official information services will continue providing updates as construction milestones progress toward projected completion.
