Concrete Crash Barriers Line Hambledon Road During Upgrade

Hambeldon Road Upgrade
Jay & Lel Civil, June 2018


Jaybro supplied Jay & Lel with nearly 300 DB80 concrete crash barriers for Blacktown’s Hambledon Road upgrade project.

The NSW Government in partnership with Blacktown City Council is set to fund the $33 million project to upgrade Hambledon Road. This thoroughfare connects the suburbs of Quakers Hill and Schofields in Sydney’s west. Furthermore, the upgrade to this high capacity urban road is essential to improving access to Schofields railway station. The station is set to become a major transport node in the system in the future.

The upgrade to Hambledon Road will also create a connection to existing roads and schools.

Blacktown City Council will contribute extra funds and manage the design and construction of the project.  Our customer Jay & Lel Civil won the contract for a major part of this project. Ultimately a two-lane rural road in Schofields will become a major four lane thoroughfare. It will extend a significant distance from Stanhope Parkway and Burdekin Road through to Schofields Road. Once completed the new road will then form part of a regional road network helping to cater to future growth. Furthermore it will improve traffic conditions and unlock more land for housing development.

This will give access to future residents with the delivery of up to 8,500 new homes in the area. The upgrade will make life easier for residents and improve the journey between home and school or home and work for many families. It is also a popular area for first home buyers and this investment in infrastructure is a positive step towards further growth in the area.


Jay & Lel Civil sought a sturdy crash barrier solution that workers could deploy along the length of the project. They required a concrete barrier that was easy to move and offered excellent protection for workers. This project also stretched over a significant distance. Therefore Jay & Lel Civil needed to source over a kilometre of barriers from a vendor that could supply with fast turnaround.


Jaybro supplied Jay & Lel with 1,160 lineal metres of our 4 metre long DB80 DeltaBloc jersey barriers to act as a temporary concrete crash barrier. RMS approved for speeds up to 100km/hr, these concrete barriers are a safe passive traffic solution. They offer minimal deflection if someone was to lose control of their vehicle or try to deliberately ram the barriers. The DeltaBloc concrete crash barrier can deflect cars at 100km/h at a 15° angle = 257mm deflection.

These concrete crash barriers are surprisingly light, flexible and rigid. Workers can bolt or pin the barriers in place depending on the application. The DB80 precast concrete crash barriers can reduce the risk of a head-on collision. They do this by preventing an out-of-control vehicle from crossing over the median strip into oncoming traffic. Therefore they are ideal for protecting both workers and pedestrian around road works.

Additionally, their unique design allows for easy transport. Fast truck-mounted crane installation is possible due to strong lifting points. At only 520kg per metre, DB80 concrete crash barriers are easy and efficient to transport and install. They are also available in 6 metre long or 2 metre long units.

The Deltabloc jersey barriers have a highly efficient coupling method without any screws. They also feature patented damping devices at the element joints.

The project is due for completion by the end of 2019.
