Frequently Asked Questions

What is the project?

The North East Road and Nottage Terrace Intersection Upgrade Project will increase the capacity for vehicles turning left onto North East Road form Nottage Terrace, creating an overall improvement of traffic flow for vehicles travelling between Main North Road and North East Road along Nottage Terrace.

Why does the North East Road and Nottage Terrace intersection need to be upgraded?

At present, the existing single left turn lane on Nottage Terrace approach queues significantly, causing long delays for peak traffic including vehicles heading north-east on North East Road through the intersection.

The primary objective of this project is to address the identified capacity problem at the intersection, and to improve other movements at the intersection to increase safety for all road users.

Why is it necessary to ban right turns in peak periods from Stephen Terrace onto North East Road as part of the project upgrade?

At present, the existing single left turn lane on Nottage Terrace approach queues significantly, resulting in long delays for peak traffic including disruptions to vehicles heading north-east on North East Road through the intersection.

In peak periods, traffic turning right from Stephen Terrace onto North East Road does so uncontrolled (with no green arrow).

This cannot be accommodated in the proposed concept design as traffic turning right cannot safety turn across the dual left turn uncontrolled.

A green arrow is not provided in the proposed concept design to reduce delays to road users and achieve project benefits.

What are the currently traffic Volumes through the intersection?

The number of vehicles turning right from Stephen Terrace onto North East Road in peak periods is relatively low compared to the total volume of traffic passing through the intersection.

A Vehicle Turning Movement Survey conducted on Tuesday, 3 September 2019 recorded 46 vehicles turning right in the AM peak hour (7:30am-8:30am) from Stephen Terrace onto North East Road and 68 in the PM peak hour (4:30pm-5:30pm).

These turning movements compare with about 5,700 vehicles passing through the intersection in the AM peak hour (7:30am-8:30am) and about 5,300 in the PM peak hour (4:30pm-5:30pm).

What will change as a result of the project?

Introducing dual left turning lanes from Nottage Terrace onto North East Road will mean that it is not safe to allow uncontrolled right turns from Stephen Terrace onto North East Road during peak periods as both lanes on North East Road will be used by vehicles turning left from Nottage Terrace

Right turns from Stephen Terrace onto North East Road will be banned from 7am-10 am and 3pm-7pm Monday to Friday. Right turns from Stephen Terrace will be allowed outside of those times.

Permanent signage will be installed to advise road users of the times right turns will be banned.

A right turn phase from Stephen Terrace onto North East Road, with a green arrow during the peak periods, would mean that the traffic delays would be worse than what is currently experienced and the intersection upgrade would have no improvement in traffic performance.

A similar right turn ban arrangement, in the morning peak period, is currently applied for the right turn movement from Dequetteville Terrace to Payneham Road.

When the right turn is banned, what is my alternate route?

There are alternate routes to access North East Road from Stephen Terrace, including:

  • Walkerville Terrace and Smith Street; or
  • Walkerville Terrace, Vale Street and Ascot Avenue.

Electronic signage will be in place to provide advance notice of traffic changes.

Will local roads be upgraded to accommodate for re-routed traffic during peak periods?

Based on the volume of vehicles performing the right turns at the North East Road and Nottage Terrace intersection the additional number of vehicles re-routing onto the local network, is considered to be minor and no infrastructure upgrades are considered necessary (in addition to what is proposed as part of this intersection upgrade) to account for the proposed right turn ban from Stephen Terrace in peak periods.

As a comparison to the number of vehicles turning right from Stephen Terrace onto North East Road (68 in the PM peak hour), there are approximately 300 vehicles per hour in the PM peak hour that turn right from Smith Street onto North East Road and about 180 vehicles per hour in the PM peak that turn right from Stephen Terrace to Walkerville Terrace.

Why is it necessary to remove on-street parking on the northern side of Nottage Terrace between Corbin Road and Hawkers Road?

The removal of the parking lane on Nottage Terrace between Corbin Road and Hawkers Road will allow for an additional left turn lane for the purpose of improving traffic flow on approach to the intersection for eastbound traffic.

What upgrade options were considered?

A range of options were developed; some of which fit within the existing road reserve and others involved road widening and property acquisition.  To achieve traffic performance benefits, it has been deemed necessary to widen the road on the north western corner of the intersection.

The preferred solution aims to balance factors including traffic performance, safety improvements, project cost and impacts.

Is property acquisition required to facilitate the project?

Residential property acquisition is required on the north-western quadrant of the intersection to facilitate the road widening. All directly impacted property owners have been contacted by the Department.

Are vegetation impacts expected as part of the preferred concept plan?

The project upgrade is in an existing built-up area and environmental impacts are expected to be minimal. Consideration is always given to limiting the removal of vegetation along project corridors as much as possible.

Opportunities to enhance the visual amenity through vegetation plantings will be investigated, in conjunction with the local Councils, during the detailed design stage of the project and we encourage community input in this area.

Will noise impacts be considered as part of the project?

The Department’s Road Traffic Noise Guidelines (the Guidelines) set out the process to be followed and criteria to be applied when assessing the road traffic noise impacts of infrastructure projects involving new roads and/or major upgrading of existing roads.

The Department will engage acoustic consultants in the detailed design phase to undertake a noise assessment for the intersection upgrade project.  Results of the assessment will be used to determine what, if any, and where noise mitigation treatments are appropriate.

Please be assured every effort is made by the Department and its construction contractors, to minimise impacts to local residents as much as practically possible.

Have improvements for pedestrians and cyclists been considered in the preferred concept design?

The design includes upgraded pedestrian crossings and traffic islands within the intersection, including new pedestrian crossing lights and ramps, and a new eastbound bicycle lane on Nottage Terrace on the approach to the intersection.

Cyclist safety has been considered through provision of:

  • a bike cut-out for improved safety for cyclists travelling east from Nottage Terrace to Stephen Terrace; and
  • a wide footpath on the north-western corner of the intersection to improve the connection between the Bikedirect network of Hawkers Road and D’Erlanger Avenue.

Will my feedback be considered even though the Department has a preferred design?

All feedback received regarding the current proposed concept design will be reviewed and considered.

Feedback is important and will continue to help inform the refinement of the design and the roll out of construction. All feedback and concerns will be considered as the project team continues to identify outcomes that deliver on the project’s objectives, whilst balancing the needs of the various stakeholders, as much as practically possible.

What happens next?

Major construction is expected to commence in mid-March 2022 and be completed in mid-2022. Further updates will be provided as the design progresses prior to works commencing.
