Infrastructure, Road and Footpath Construction

The bridge over Fifth Creek, near 780 Montacute Road, Montacute, will be replaced. Work will start this Monday, 13 January, and is expected to continue until early March. The bridge will remain open during this period, but various speed and lane restrictions will be in place. Please plan your travel accordingly and allow extra time for potential delays.

Department of Infrastructure and Transport will be testing new safety equipment installed as part of the Heysen Tunnels upgrade.

When: Saturday 11 January to Sunday 19 January 2025, weather permitting.

Hours of work: 7pm to 6am (each night).

Where: South Eastern Freeway, Adelaide-bound and Crafers-bound Heysen Tunnels and approaches.

How this affects you: To minimise impacts to road users, DIT will undertake the testing at night, and there will be some changes to traffic conditions during this process.

Some nights, they will need to close one tunnel for testing. Traffic in both directions will use the other tunnel with a contraflow arrangement in place.

Other nights, they will need to close one or both tunnels and their approaches and divert traffic via Mount Barker Road. Please read below for planned traffic arrangements during this time.

Adelaide-bound traffic

7pm to 9pm: Initial speed and lane restrictions for Adelaide-bound traffic.

9pm to 6am: All road users, including emergency services and heavy vehicles, will need to detour via Mount Barker Road.

Crafers-bound traffic

7pm to 11pm: Initial speed and lane restrictions for Crafers-bound traffic.

11pm to 6am: Heavy vehicles will be able to use the South Eastern Freeway but will need to wait for the freeway to reopen after short intermittent closures in the vicinity of the Heysen Tunnels. Each closure will extend for approximately 15 minutes.

All other road users, including emergency services, will need to detour via Mount Barker Road.

DIT will notify road users about upcoming detours via onsite messaging boards.

Speed and lane restrictions will be in place. Please plan ahead, allow extra travel time and follow the detour signs and direction of traffic management staff. We’ll have temporary electronic signs in place to direct road users while the permanent electronic signs are being tested.

Although delays may occur, there will be no change to public transport services.

Safety ramps are available on Mount Barker Road (Eagle on the Hill) and the South Eastern Freeway (safety ramp between Heysen Tunnels and Tollgate).

In the event of a bushfire, other emergency, or on catastrophic fire days, all lanes will be open in both tunnels and posted speed limits will be reinstated for both carriageways.

What we are doing

The Heathfield water tanks ensure the reliable supply of potable water to SA Water customers in Heathfield and surrounding Adelaide Hills suburbs. To protect this critical infrastructure, SA Water will soon install security fencing along the boundary of the tank site.

Why we are doing it It is our priority to ensure our infrastructure is properly secured to continue delivering safe, healthy drinking water to the community and provide a safe work environment to our employees. This project will also protect our infrastructure from potential bush fire risks, by establishing a fuel break (approximately 5 meters wide) inside our boundary within the clearance zone required to construct the fence. Clearance will be undertaken in accordance with the Native Vegetation Act and SA Water’s standard operating procedures. Importantly, mature trees will be retained through careful alignment of the new fence to minimise impacts.

When is it happening Vegetation clearance along the boundary is due to commence mid-November 2024, followed by construction of the fence. We expect these works to take approximately 4 weeks to complete. Works will typically be undertaken Monday to Friday from 7am to 5pm.

Keeping the community updated If you have any questions about the works, please contact Christian Mular on 0403 183 399 or christian.mular@sawater.com.au

The Department for Infrastructure and Transport (the Department) is upgrading a series of bridges and culverts across regional South Australia to extend the service life of the structures and improve safety for road users.

As part of these works, the Department are upgrading the bridge over Junction Creek, on Onkaparinga Valley Road, near Bridge Street Balhannah. These works are jointly funded by the Australian and South Australian governments.

What to expect

Works to upgrade the bridge over Junction Creek in Balhannah are continuing with the majority of works being undertaken during the day. Traffic will be moved onto the westbound lane from 4 September 2024, so the Department can work on the other side of the bridge.

Work will be undertaken between 7am and 5pm, Monday to Saturday. Some night works will be required in mid-September for approximately 3 nights between 7pm and 5am, weather permitting to carry out asphalt works. Properties in the vicinity of these works will be provided advance notice prior to night works commencing and onsite signage will be in place.

To safely facilitate these works, traffic will continue to be reduced to a single lane on Onkaparinga Valley Road with temporary traffic signals in place to control the direction of traffic, at all times. Speed restrictions will be in place throughout the work area for the duration of the project. Please follow traffic management directions while works are in progress and take extra care when workers are on site.

During the works, there will be some noisy disruptions from time to time, and the Department will do their best to keep the noise to a minimum.

Bridge works are expected to be complete late September 2024, weather permitting. Minor finishing works will be undertaken following the completion of these works.

Intersection of Onkaparinga Valley Road, Nairne Road, and Junction Road, Balhannah

The Department for Infrastructure and Transport are delivering the Adelaide Hills Productivity and Road Safety Package to upgrade key strategic arterial roads in the region. The road improvements will support economic growth, improve road safety, and increase fire resilience. The $150 million initiative is jointly funded by the Australian Government (80%) and South Australian Government (20%) over five years.

When?

What's happening?

Site investigation works, including geotechnical drilling and surveys, will be undertaken at the Onkaparinga Valley Road, Nairne Road and Junction Road intersection. These investigations will help inform the detailed design of the intersection.

How might this affect you?

To do this work safely, there will be speed and lane restrictions in and around the intersection. Please plan your trips, be cautious around workers, and follow the speed limits and signage.

Access to businesses and surrounding properties will be maintained throughout the works, and we will ensure every effort is made to minimise impacts to surrounding properties as practically possible.

Minor noise disturbances can be expected while works are being undertaken, but we will minimise any disturbance to residents as much as practically possible.

Update 7 May 2024

Croft Road will be CLOSED from Wednesday 8^th May until Wednesday 15^th May, including the weekend (11^th / 12^th May) for the final stage of construction works. The full closure is required to allow the road base stabilisation works to be undertaken safely as the specialised construction plant is large and the road is narrow and windy.

The detour via Edwards Hill Road will remain in place to provide access to the Fox Creek Bike Park upper car park and Anderson Hill Winery.

Upgrade works have commenced on Croft Road in Lenswood, between Coldstore Road and the Fox Creek Bike Park upper car park.

This section of Croft Road is approximately 1.8km long. The works will include minor widening, changes in geometry to better meet modern design standards, installation of safety signage and construction of a stabilised pavement with a sprayed seal wearing course. The project will provide a safer, smoother ride for motorists as they traverse Croft Road as well as reduced ongoing maintenance for Adelaide Hill Council.

The project will commence in late April 2024 or early May 2024, weather permitting.

During this period this section of Croft Road will be closed during work hours (7am – 5pm Mon-Fri), with a detour in place to the Fox Creek Bike Park upper car park via Edwards Hill Road.

The road will be made safe and opened after hours and on weekends, with reduced speed limits in place.

A notification board has been installed at the Coldstore Road end to provide advanced notice of the road closure.
