Infrastructure, Road and Footpath Construction

Mount Lofty Summit Road will be closed at times on Thursday 13 April 2023 for planned works to the Mt Lofty telecommunications tower.

Aerotech Helicopters have been engaged to remove a section of the Mt Lofty tower.

Due to the safety requirements of this task, Mount Lofty Summit Road will need to be closed between Owens Street and the Mount Lofty Summit Carpark intermittently, depending on weather conditions.

The road will be closed twice for up to 45 minutes, between the hours of 8am and 3pm. The exact time of the required closure will depend on weather conditions. The road will be open at all other times.

Adelaide Traffic Control has been engaged to ensure the road is safely closed and to assist and direct traffic as needed throughout the day.

Adelaide Traffic Control can be contacted via email: planning@adelaidetrafficcontrol.com.au

Start of initial activities - Crafers bound tunnel

The Department for Infrastructure and Transport (the Department) is undertaking a major upgrade of the Heysen Tunnels to address current tunnel elements that are at the end of their service life, improve safety and provide improved traffic management and incident response capabilities.

The upgrade will include the design and installation of new tunnel lighting, ventilation, fire suppression and Intelligent Transport Systems.

The Australian and South Australian governments are jointly funding the Heysen Tunnels Safety Upgrade, which is expected to be completed in 2024.

Initial activities, including additional investigation works and the start of tunnel lining repairs are planned to start from Sunday, 19 March 2023.

To minimise the impacts to road users, the majority of works will be undertaken Sundays to Thursdays between 8pm and 6am. It is not anticipated that works will be undertaken on Friday and Saturday nights, or on public holidays, however advance notice will be provided by on site messaging boards if this changes.

From Sunday, 19 March 2023, the Crafers bound (up-track) tunnel will close between 8pm and 6am. During these closure times, the Adelaide bound (down-track) tunnel will accommodate traffic in both directions, via contraflow (see map and further information under 'Latest News and Publications' on the project website).

Works are expected to continue in the up-track tunnel for approximately two months. Further updates about this project and associated impact will be provided.

The Department appreciates your patience and co-operation whilst these important works are undertaken.

As a result of the recent storm event that occurred in November, multiple mature trees within the Paracombe play space area have been extensively damaged. Council has undertaken detailed tree assessments of three Monterey cypress trees (Cupressus macrocarpa) situated to the south-western side of the play space area. As a result of these assessments, significant structural defects have been identified within two of the three trees. Due to limited pruning options being available, two of the trees require complete removal. Unfortunately, the third tree now also requires complete removal due to its reduced ability to endure high wind events as a result of the sudden loss of protection previously received from the neighbouring trees.

When will works commence and the play space re-open?

Works are scheduled to commence on Thursday 15th December and will be completed by COB Friday 16th of December. The play space will be reopened to the public upon completion of the works. Throughout the duration of the works, access to the Hall and Oval facilities will be maintained.

Why do these trees need to be removed?

These trees are significantly damaged and compromised. They pose an increased risk of falling over the play space area, where people gather and play. Council is responsible for people's safety and committed to ensuring risks associated with trees are maintained to an acceptable level.

Why can’t we just prune the trees and they will grow back?

Unfortunately, Cypress trees when pruned do not have the ability to regenerate and form new tree canopies. Without this ability, the play space will receive limited shading during summer periods. The removal and planting of new trees will enable the development of larger more sustainable trees that will provide long term benefits to the community for future generations.

What will you replant and when?

Adelaide Hills Council will work with the Paracombe Recreation Ground Committee on replanting numerous advanced trees during the winter period of 2023. Consideration will be given to the best type of tree species, including those which will provide maximum shade to play space users and also compliments and improves the amenity of the site.

If you have any questions, please do not hesitate to contact Senior Arborist Damian Brennan on 0447 401 183.

We apologise for any inconvenience that these works may cause.
