The new section of the North-South Motorway has now increased to 80km/h.

Managing traffic

Traffic flow

When construction works affect the arterial or local traffic network, traffic management plans are prepared to help minimise impacts to road users, as much as practically possible. During peak hours (6am – 7pm Monday to Friday) the R2P Alliance will maintain two lanes in each direction on both South Road and Regency Road, and will maintain a minimum speed of 40 km/h. Night works and works carried out on weekends will require speed and lane restrictions to be put in place.

Traffic management strategies

To ensure the safety of pedestrians, motorists, cyclists and workers during the project, various forms of temporary and permanent traffic management will be in place including:

  • reduced speed limits;
  • road, lane and pathway closures;
  • road diversions and construction of temporary roads;
  • road barriers and fencing around the construction zone;
  • temporary traffic signals and stop-slow traffic controllers;
  • static signage;
  • temporary bus-stop relocations;
  • temporary parking restrictions; and
  • changes to pedestrian and cyclist access.

Communicating traffic changes

Advance notice is provided to the community about traffic changes in a number of ways, including:

  • Variable Message Signage and static signage;
  • email notifications to stakeholders and road users;
  • notifications to the local community;
  • via the SitePodium app;
  • information on DIT and R2P Project websites;
  • DIT social media updates; and
  • advertisements in local newspapers and on the radio.

Traffic conditions progressively change during construction and we ask that commuters are alert, patient and pay close attention to road signage. Where possible, plan your journey in advance and allow a little more travelling time.

Traffic management liaison groups

The R2P Alliance uses regular traffic management liaison group meetings with key stakeholders including The Department for Infrastructure and Transport, the Traffic Management Centre, Adelaide Metro, emergency services, and local councils.

Traffic management liaison groups allow key stakeholders to discuss and contribute to the planning and implementation of traffic management throughout the project. Key discussion points include:

  • safety;
  • community feedback;
  • timing of major traffic switches;
  • status of traffic operations and performance;
  • coordination with other nearby works and events;
  • emergency service access; and
  • communication planning for future works.

Pedestrians and cyclists

Temporary fencing, road barriers and signage are used during construction projects to delineate construction zones and ensure that motorists, cyclists and pedestrians can safely navigate around works sites. As works progress and access routes change, signage and notifications are used to advise pedestrians and cyclists of any detours.
