Samantha Riley Drive Stage 3 Upgrade Underway

The completion of the Samantha Riley Drive upgrade, in North Kellyville, is one step closer after The Hills Shire Council awarded a construction tender for Stage 3 of the project. The tender was awarded to Menai Civil Contractors at the Ordinary Meeting of Council on Tuesday, March 24.

Stage 3 works commenced on 20 April, 2020. Stage 3 is the section between Hezlett Road/James Mileham Drive and Foxall Road. When complete, the road will be upgraded to a four lane, divided carriageway sub arterial road.


The work required as part of the upgrade includes substantial excavation to lower the existing road crest by two metres and construction of masonry block retaining walls in order to meet Australian road safety standards regarding sight distance and gradient.

Additional works such as kerb and guttering, road drainage, new pavement, regulatory signage and line marking will also take place.

Current works include:

  • Block retaining wall placement and footing (north side)
  • Boundary retaining and fencing (south side)
  • Stormwater drainage and sewer adjustments
  • Pavement sub-base work
  • Verge preparation


Road closure and detour information 

This detour is now in place.

Due to the difficult nature of the construction work, this section of Samantha Riley Drive is closed to all traffic and a detour around the work zone will operate for the duration of the project. A traffic detour map can be viewed below.

Mayor of The Hills Shire, Dr Michelle Byrne said a full road closure is the safest, quickest and most cost effective option. Read more here.

During the temporary closure, a formal detour will operate via Hezlett Road, Goodison Street and Foxall Road. In order for the detour to operate efficiently, a number of traffic control devices will operate for the duration of the project. This includes temporary roundabouts at Hezlett Road/Goodison Street and Goodison Street/Foxall Road intersections. Other diversion routes will be in place as works are carried out, including at Withers Road and Foxall Road; and at James Mileham Drive and Marella Avenue.

No stopping signage will also be placed along Goodison Street while these diversions are in place.

To support the detour route, temporary ‘No Parking’ zones will also operate along James Mileham Drive during the weekday peak hours between 7am-9am Monday-Friday on the northern side and 5pm-7pm on the southern side.

History of the Upgrade of Samantha Riley Drive to a Four Lane Sub Arterial Road

Works on one of the biggest infrastructure projects in The Hills - the upgrade of Samantha Riley Drive Kellyville has seen a number of milestones being achieved.

This project is one of the most complex road projects Council has carried out, involving land acquisitions to enable the road to be widened, identifying and relocating high and low-voltage power, relocating telecommunications, water mains, stormwater drainage and other utilities and seeking approvals from multiple agencies to achieve these outcomes. 

The upgrade will see the section of Samantha Riley Drive east of Windsor Road widened to a four-lane carriageway, with three major intersection upgrades at Redden Drive, Hezlett Road and Foxall Road.

The undergrounding of overhead electrical cabling and power pole removal works was completed in September 2019 enabling road work to resume.
