Fairfield Traffic Changes October 2026: Major Road Closures Starting in Horsley Park

By BJ Gregory, Liverpool Property Expert · Gregory Property Agents · 21 October 2026 · Traffic Committee Meeting: 12 October 2026

If you live, work or travel through Horsley Park, mark 9 November 2026 in your calendar. The Fairfield Traffic Committee has approved Fairfield traffic changes and rolling road closures across three major roads for an 11-month recycled water pipeline project servicing the NextDC S4 data centre facility.

More Information about the Data Centre can be found here

This update covers everything Fairfield residents need to know about the approved closures, construction methods, detour routes and how to minimise disruption to your daily routine.

What Roads Are Closing in Horsley Park?

The Traffic Committee approved temporary full road closures on three roads in Horsley Park to facilitate construction of a new recycled water pipeline by civil engineering contractor Killard/Ferrycarrig (KF):

Why Are These Road Closures Happening in Horsley Park?

The closures are required to construct a new recycled water pipeline from Redmayne Road to the NextDC S4 data centre facility in Johnston Crescent, Horsley Park. The project was approved by the Independent Pricing and Regulatory Tribunal (IPART) on 2 October 2026.

The recycled water will be supplied by coNEXA SYD as part of the Rosehill Scheme Extension, which connects to the existing recycled water plant at Fairfield operated by AquaNet.

What Construction Methods Will Be Used?

The contractor will use three different construction techniques depending on site conditions:

1. Open Trenching: Traditional excavation method requiring full road closure due to excavation depth, construction equipment, pipe storage and worker safety
2. Horizontal Directional Drilling (HDD): Trenchless method that drills underground, but still requires significant surface space for drilling rigs, pipe welding and launch/receiving shafts
3. Microtunnelling: Advanced underground tunnelling using purpose-built machines, requiring large excavations at launch and receiving points (typically 7m × 4m and 5m × 3m)

How Will Traffic Be Managed During Horsley Park Road Closures?

Killard/Ferrycarrig has committed to the following traffic management principles:

• Only one local road closure at a time — all other work sites will use Stop/Slow traffic control
• Roads reopen each evening — closures operate during construction hours only (6.30am–6.30pm)
• Bus services unaffected — Route 738 loop will be allowed through closures at all times
• Emergency vehicle access maintained — ambulance, fire and police vehicles can access the area
• Resident access maintained — local residents will be able to reach their properties, though some delays are expected
• Heavy vehicle access where practicable — trucks over 5 tonnes travelling north on Wallgrove Road will be let through the western closure on Redmayne Road

What About the School on Walworth Road?

Special conditions require the contractor to minimise impact on traffic moving to and from the public school on Walworth Road. The exact closure dates for Walworth Road must be provided to Council at least 3 weeks in advance to allow proper planning around school terms and peak drop-off/pick-up times.

Detour Routes for Horsley Park Road Closures

Detailed detour maps have been approved by Transport for NSW and will be clearly signposted. Traffic controllers will be positioned at key points to safely manage vehicle movements through and around work zones.

The approved Traffic Guidance Schemes (TGS) comply with Australian Standard AS1742.3 and Transport for NSW's 'Traffic Control at Worksites' standard.

What This Means for Horsley Park Property Owners

An 11-month construction period with rolling road closures will affect daily routines, property access and potentially buyer interest if you're considering selling during this time. Here's what property owners should consider:

• Access delays: Budget extra travel time during construction hours, especially during morning and afternoon peaks
• Noise and disruption: Open trenching, drilling and heavy machinery will operate between 6.30am and 6.30pm (noise must comply with the Noise Control Act)
• Property marketing: If selling, factor in construction activity when scheduling inspections and open homes
• Long-term benefit: Once complete, the recycled water infrastructure supports the growing Western Sydney data centre precinct, which may increase employment and economic activity in the area

Who Approved These Fairfield Traffic Changes?

The Fairfield Traffic Committee approved the road closures at its meeting on 12 October 2026. The committee included:

• Mayor Frank Carbone (Chairperson)
• Councillor Barkho
• Councillor Karajcic

The motion was carried unanimously with strict conditions including:

• Fairfield Police Local Area Command must be informed and their conditions followed
• Road Occupancy Application authorised before works commence
• Emergency services notified of all closures
• Public liability insurance of $20 million submitted to Council
• All traffic guidance schemes signed by suitably qualified persons

Other Fairfield Traffic Changes Approved in October 2026

The same Traffic Committee meeting approved or noted several other traffic matters affecting Fairfield residents:

The Boulevarde, Fairfield Heights: Peak-Hour Parking Restrictions

Status: Approved

New "No Stopping" restrictions on The Boulevarde north of Karabar Street during morning and afternoon peak periods (Monday to Friday). About 5 parking spaces will be unavailable during peaks to improve traffic flow for vehicles turning right into Stanbrook Street.

Mimosa Road and Quarry Road, Bossley Park: Traffic Signals

Status: Update only, not approved

Council received a status update on proposed traffic signals at this intersection. Estimated cost is $1.32 million. Council will seek grant funding but construction has not been approved yet.

Polding Street, Prairie Vale Road and Lily Street, Wetherill Park

Status: Report noted, no new works

The committee noted ongoing queuing issues on Lily Street since signal changes. Council has added signage and extended the kerbside lane. A possible future upgrade involves an extra right-turn lane on Prairie Vale Road.
