Great South Road, Church Street and South Eastern Highway - Intersection Improvements Great South Road, Church Street and South Eastern Highway - Intersection Improvements

Consultation status: closed 22 February 2017

We have identified an opportunity for improvements at the intersection of Great South Road, Church Street and the South Eastern Highway.

On the Great South Road northbound approach, we are proposing several modifications:

  • Adding a through-lane heading north across the intersection.
  • Converting the far right lane to right-turn only.
  • Removing the left-turning slip lane and the signalised crosswalk across the slip-lane, and replacing these with a pedestrian zebra-crossing and give-way controls.
  • Extending the length of the left-turn lane with a kerb cut-out and realignment of the footpath.
  • Kerb buildout on southern corner of the intersection.
  • Reconstructing the traffic island.
  • New road markings.

Why the changes are required

Great South Road is a main freight route and carries a high volume of traffic. Due to this it becomes very congested at peak times causing significant queues and delays.

The aim of this proposal is to improve the performance of this intersection, for both the public and freight, particularly for northbound movement.

Thank you everyone for your feedback.

The proposal received positive feedback with some concerns raised by respondents. After reviewing this feedback and all other supporting evidence, the proposal will proceed without changes to the next stage of detailed planning.

Specific feedback and proposed solution

  • Request to narrow the other two slip lanes and add pedestrian crossings. Question about why there are slip lanes at this location. The location of the proposal is a major intersection which experiences congestion at peak times. The slip lanes exist to improve operational efficiency and are sufficiently wide to accommodate the turning path of large vehicles. The slip lanes also enable pedestrians to cross the main road without being in conflict with traffic and removing them would result in longer crossing distances for pedestrians.
  • Request for a second right-turn lane for vehicles turning right from Great South Road into Church Street. Converting one of the southbound straight-through lanes to a shared straight-through and right-turn lane has been considered. However, at this stage it is not proposed for implementation as part of this change.
  • Request for a protected cycle track next to the kerb, bike lights and staged turn-phases. This intersection is located on a key freight route to and from the motorway and along Great South Road. The purpose of the works is to assist the movement of freight, particularly along Great South Road. We recognise that it is not desirable to mix vulnerable road users and heavy vehicles together. The project will be reviewed during the detail design stage to consider what facilities can be incorporated to safely assist cyclists.
  • Concern about the left-turn lane being removed as this is a main freight route. The capacity of the two left turn lanes is currently reduced by queues of traffic heading straight over the intersection (northbound) on Great South Road. These northbound queues have the effect of blocking access to the left-turning lanes, resulting in the left-turning lanes frequently operating as a single lane. Larger vehicles also usually turn one at a time, as truck drivers are aware of the turning path of other trucks.
  • Concern that the turning path of trucks will lead them into the outside lane of Church Street, when most will want to be in the left-hand lane for the next two intersections. Tracking at the intersection has been completed and trucks are able to turn into the left hand lane on Church Street. The proposal also includes a modification to the radius of the kerb to make the turn slightly easier to complete, which will further assist trucks turning into the left hand lane.
  • Concern that businesses could be impacted if the road is closed. During construction, traffic management at the intersection will take into account the high traffic volume through this intersection and the fact that it is on a key freight route to and from the motorway. At this stage the construction methodology has not been determined, but a rigorous process is used to approve any traffic management measures. Given the key nature of this intersection, it is likely that if a closure is required it would only occur overnight. However, this will be determined at a later date.
  • Request for additional works. If you would like your request to be considered by AT for future development works, please provide feedback here.

Next stage

We expect to introduce this work in July 2017 and throughout 2017/18, subject to any further changes in design or funding issues. Contractors will issue a 48-hour notice to all residents in the area prior to starting construction work.
