Bangor Bypass Stage 1

The Bangor Bypass is being delivered in two stages.

Stage 1 was opened to traffic on 7 February 2005 and provides a four-lane, divided road between Woronora Bridge and Alfords Point Road, bypassing Menai Road.

Stage 1 was fully funded by the State Government and cost approximately $95 million.

The Bangor Bypass stage 1 provides:

• Shorter travel times between Sutherland and Bankstown.
• Improved air quality and less traffic noise for many local residents.
• Improved safety for all road users.
• Improved access to Menai Town Centre, local schools and residences.

The speed limit on the Bangor Bypass was reviewed in December 2005 and is now sign posted at 80km/h.

Menai Road is now a local road with a 4.5 tonne load limit between Yala Road and Akuna Avenue.

Old Illawarra Road is now a local road between Menai Road and Marsden Road with a 4.5 tonne load limit between Barry Road and Marsden Road and a 3.3 metre height restriction under the Bangor Bypass (east-west link).

Noise assessment - Stage 1

Stage 1 of the Bangor Bypass project was completed and opened to traffic in February 2005.  A number of measures were provided to reduce the impact of traffic noise including:

• Changes to the vertical and horizontal alignments of the Bypass.
• The use of a quieter road surface material.
• The construction of noise barriers along the Bangor Bypass road corridor.

The RTA is required under the project conditions of approval to monitor and assess operational traffic noise after opening the project to traffic and to install all reasonable and feasible noise mitigation measures. 

This assessment has been completed and a report called Bangor Bypass Operational Noise Evaluation is available below (as a PDF file) and at Menai Library.

The assessment identified homes that qualify for additional treatment.  The aim of this treatment is to compensate for the effect of closing windows to reduce the impact of traffic noise in homes. 

A noise mitigation specialist was engaged by the RTA to make arrangements to visit identified properties and assess the scope of work for each eligible room.
