Background

The Princes Highway and King Georges Road are one of the main arterial routes that connect the Sutherland Shire and Sydney. This location has been identified as part of the Gateway to the South program to improve the efficiency of the intersection and provide improved travel times for road users travelling along the corridor.

Vehicle volumes in the morning and afternoon peak periods

Around 6500 vehicles per hour travel through the intersection of the Princes Highway and King Georges Road towards the Sydney CBD in the morning peak period.

Around 6400 vehicles per hour travel through the intersection of the Princes Highway and King Georges Road on their way home in the afternoon peak period.

Revised proposal

After considering all responses, along with the proposal’s aims and design requirements, we are now inviting your feedback on a new proposal to install a concrete median eastbound on Stuart Street close access out of Stuart Street onto the Princes Highway and King Georges Road . This proposal aims to improve the flow of traffic travelling through the intersection of the Princes Highway and King Georges Road and access into Blakehurst.

As part of the proposal, vehicles exiting Stuart Street will be redirected via alternative routes to access King Georges Road and the Princes Highway (see Alternative access).

Benefits

Reduced travel times

Vehicles travelling north and south during peak periods on the Princes Highway and King Georges Road will experience reduced travel time delays as a result of the proposed improvements.

Due to the high volumes of traffic using this intersection, it is estimated that there will be a reduction in accumulative delays of around 15 hours travel time in the morning peak period through the intersection of the Princes Highway and King Georges Road.

Motorists turning right from the Princes Highway onto the King Georges Road and into Stuart Street will experience improved access to Blakehurst as a result of increased efficiency at the intersection.

Safety

This proposal will improve safety for motorists turning into Stuart Street and King Georges Road from the Princes Highway by removing the turning phase for vehicles travelling out of Stuart Street at the intersection.

Risk of rear-end crashes as a result of cars queuing from the right turn bay into the Princes Highway will also be reduced due to improved traffic flow through this intersection.

Change in Stuart Street access

A detailed assessment of the vehicle volumes travelling out of Stuart Street during peak periods shows around 110 vehicles per hour in the morning peak and 55 vehicles per hour in the afternoon peak. Lower vehicle volumes have been recorded travelling outside of these peak periods.

Restricting access out of Stuart Street will improve the efficiency at the intersection of the Princes Highway and King Georges Road for around 12,900 vehicles who travel through the intersection during peak periods. Local traffic will be rerouted to access the Princes Highway and King Georges Road via a range of alternative local roads.

Alternative access

The two alternate routes recommended are via Phillip Street and Water Street. Alternate routes depend on the origin and destination of the motorist and signage will be installed to inform motorists of the change in access. 

Vehicles travelling north will be able to access the Princes Highway and King Georges Road via Phillip Street. Vehicles travelling north-east will be able to access the Princes Highway via Water Street.

Additional travel times

Motorist rerouting from Stuart Street can expect an additional travel time of 20 – 70 seconds via the recommended alternatives of Phillip Street or Water Street.

Assessment of these routes has shown a low impact for local residents and motorist as a result of these alternative routes. Traffic modelling at the intersections of the Princes Highway and Water Street and King Georges Road and Phillip Street show minor impact to the efficiency of these intersections.

Original proposal

We sought feedback between December 2015 and January 2016 on a proposal to ease congestion at this intersection which included changing the access into Stuart Street and King Georges Road from the Princes Highway.

We received feedback from over 350 people with most unsupportive of the proposal. We have prepared a Community Consultation Report which summarises the matters raised and our response.

Following a review of the feedback, we have decided not to proceed with the original proposal at this stage.

Next steps

We will carefully consider all feedback received before deciding how to proceed with this proposal. A community consultation report will be prepared, summarising the matters raised and our responses.
