Mount Johns Flood Immunity Project: Alice Springs

The Northern Territory Government allocated funds in the 2015/2016 budget to investigate ways to improve flood immunity in the Mount Johns Valley and Desert Springs areas of Alice Springs.

Currently, when the Todd River floods, residents and businesses in these areas are unable to access the Alice Springs CBD or Stuart Highway, as the Casino (Taffy Pick) causeway and Tuncks Road floodway are closed.

The only available access to the area is through a Power and Water service road that is opened to the public during critical events. This private service road is designed for access to PWC sites only and is not built to Australian Road safety standards.

The investigation identified five technical design options to improve flood immunity, these being:

  1. A connector road from Stephens Road to Sadadeen Road – direct route
  2. A connector road from Stephens Road to Sadadeen Road - eastern route
  3. A connector road from Tuncks Road to Sadadeen Road - via the Power and Water access road
  4. A high level bridge over the Todd River at Stephens Road
  5. A high level bridge over the Todd River at Tuncks Road

Details regarding each of these options are included in the attached map (4.9 mb)

The Alice Springs community is invited to provide feedback on the technical design options, before a final preferred option is identified.
