Dalziel Road

Last updated: 19 Oct 2026 10:13am

We're consulting on two options for reducing the speed limit on a section of Dalziel Road from 70 km/h to either 50 km/h or 60 km/h to improve safety and better reflect how the road is used.

We want to hear your views on the proposed change. Tell us what you think before public consultation closes at 5pm on Monday 30 November 2026.

Background

The current speed limit on Dalziel Road is 70 km/h.

We first proposed reducing the speed limit on this road to 60 km/h in our draft Speed Management Plan, which was open to public consultation in 2023.

We are consulting again following the introduction of the Government's Land Transport Rule: Setting of Speed Limits 2024, which changed the process for setting speed limits.

About this road

Dalziel Road is a residential road with increasing traffic volumes and turning movements as new housing development occurrs in the area.

Residents of the new subdivision currently rely on Dalziel Road to access nearby bus stops, local destinations and Taieri Road while the planned subdivision connection to Taieri Road remains incomplete.

Reasons for reducing the speed limit:

  • Council has received reports of safety concerns involving vehicles turning into and out of the Macleod Avenue subdivision.
  • Local residents have requested a lower speed limit on Dalziel Road.
  • Pedestrian and cyclist activity has increased on a section of road with limited shoulder width.
  • Dalziel Road also provides access to Frasers Gully walking track, resulting in additional pedestrian activity.
  • The road has several rises and dips that can reduce visibility for road users.
  • The average operating speed is approximately 62 km/h, which is already below the current posted speed limit of 70 km/h.
  • Two temporary speed humps and advisory speed signs have been installed near the Macleod Avenue intersection, requiring vehicles to slow significantly. A reduced speed limit would align with these traffic-calming measures.

The proposals

Option 1 - Reduce the speed limit on Dalziel Road from 70 km/h to 50 km/h

Travel time impact: Approximately 12 seconds

The proposed change would reduce the speed limit on Dalziel Road between Brinsdon Road and Three Mile Hill Road from 70 km/h to 50 km/h. The proposed speed limit would apply over a 1.39 km section of road.

This option would provide consistency with the existing 50 km/h speed limits that apply within Brockville and on adjacent sections of Dalziel Road. It would also better reflect the increasingly residential nature of the area, growing pedestrian and cyclist activity and the changing function of the corridor.

Option 2 - Reduce the speed limit on Dalziel Road from 70 km/h to 60 km/h

Travel time impact: Approximately 6 seconds

An alternative option is to reduce the speed limit on Dalziel Road between Brinsdon Road and Three Mile Hill Road from 70 km/h to 60 km/h. The proposed speed limit would apply over a 1.39 km section of road.

Like Option 1, this reduction would better reflect the changing character of the area, including increased residential development, additional turning movements associated with the Macleod Avenue subdivision, and growing pedestrian and cyclist activity along the corridor.

Compared with a 50 km/h speed limit, this option would result in smaller reductions in vehicle speeds and correspondingly lower safety benefits.

Option 3 - Status quo

No change to the current 70 km/h speed limit.

Requirements under the Rule

  • Cost benefit disclosure statement

    The Rule 2024 requires us to complete a cost benefit disclosure statement for the proposed speed limit changes. This sets out the expected impact of the speed limit changes on safety and travel times, and the expected implementation cost.

    Option 1 – Cost benefit disclosure statement:
    Road Dalziel Road – option 1
    Distance 1.39 km
    Existing Speed Limit 70 km/h
    Proposed Speed Limit 50 km/h
    Number of crashes in last 5 years 2
    Estimated reduction in number of crashes each year 0 serious injury crashes
    0.2 minor injury crashes
    0.2 non-injury crashes
    Current average operating speed 62 km/h
    Decrease in expected mean vehicle operating speed  8.0 km/h
    Estimated impact on individual travel time 12 seconds
    Estimated impact on collective travel times based on annual average daily traffic volumes 1,734 hours
    Implementation cost $1,500
      
    Option 2 – Cost benefit disclosure statement:
    Road Dalziel Road – option 2
    Distance 1.39 km
    Existing Speed Limit 70 km/h
    Proposed Speed Limit 60 km/h
    Number of crashes in last 5 years 2
    Estimated reduction in number of crashes each year 0 serious injury crashes
    0.2 minor injury crashes
    0.2 non-injury crashes
    Current average operating speed 62 km/h
    Decrease in expected mean vehicle operating speed  4.0 km/h
    Estimated impact on individual travel time 6 seconds
    Estimated impact on collective travel times based on annual average daily traffic volumes 807 hours
    Implementation cost $1,500

  • Role and function of the road

    Role and function of the roadUrban fringe connector road providing access to residential areas and local destinations.
    How it’s usedDalziel Road is used by residents travelling to and from Brockville, people accessing Frasers Gully walking track, people accessing the new subdivision at MacLeods Avenue, and vehicles travelling to two city water treatment plants.
    Why a speed reduction has been proposed over other measuresA speed reduction is proposed because the area is experiencing residential growth, increased turning movements associated with the Macleod Avenue subdivision, and increased pedestrian and cyclist activity on a road with limited shoulder width. Lowering the speed limit is a relatively low-cost measure that can improve safety without requiring significant infrastructure upgrades.
    Alignment of proposal to the road safety aspects of the GPSA speed limit reduction on Dalziel Road aligns with the road safety objectives of the Government Policy Statement on Land Transport by supporting a safer transport system, improving safety for pedestrians and cyclists, and reducing the likelihood and severity of crashes as traffic volumes and residential activity continue to increase in the area.
