M1 Princes Motorway projects
Mount Ousley Road, renamed the M1 Princes Motorway, carries significant commuter, heavy vehicle and recreational traffic.
Roads and Maritime Services has a number of projects being carried out to improve safety for road users in this area including:
- Safety upgrade for northbound traffic entering the M1 from Picton Road
- Interchange at the intersection of M1 and Old Mount Ousley Road.
Safety upgrade - Picton Road/M1 intersection (northbound)
Roads and Maritime has completed the safety upgrade at the intersection of the M1 Princes Motorway (formerly known as Mount Ousley Road) and Picton Road. The upgrade has improved safety by adjusting the access to Sydney from Picton Road to remove the current T-intersection and building an acceleration lane on the M1 Princes Motorway.
Please see the Picton Road/M1 intersection project page.
Mount Ousley interchange
Roads and Maritime has started planning for an interchange on the M1 at the base of Mount Ousley.
The interchange will look at future traffic growth and improve road safety at this location.
Mount Ousley heavy vehicle rest area
In March 2013, the Australian and NSW Governments announced $8.09 million to construct a north bound heavy vehicle rest area at the intersection of the M1 Motorway and Clive Bissell Drive, Mount Ousley.
This location is currently used as an informal rest area. The project will provide additional capacity, new facilities and safer access for heavy vehicles.
The project will provide:
- Safer access into the area
- Parking space for at least 10 Heavy Vehicles
- Toilets, rubbish bins and sheltered areas, including picnic tables
- Designated space for Driver Reviver operations
- Cater for truck drivers in managing driver fatigue.
Improvements between Figtree and Dapto
As part of the planning process, Roads and Maritime will be investigating a range of design options to address the future needs of the region. The design process will identify potential upgrade options including:
- Widening the motorway to provide extra lanes
- Upgrading existing ramps to increase capacity and improve safety
- Adding new ramps and traffic signals at some interchanges
- Adding variable speed limit signs and other road signage.
The upgrades will aim to:
- Improve travel time and efficiency for motorists
- Improve freight accessibility into and out of the region including access to Port Kembla and heavy vehicle access to the Shoalhaven and South Coast
- Cater for traffic growth as a result of nearby development.
Improvements between Picton Road and Bulli Tops
The M1 Princes Motorway between Picton Road and Bulli Tops is currently two lanes in each direction.
This section of road carries about 37,000 vehicles a day, 15 per cent of which are heavy vehicles. Traffic numbers will continue to increase along this route.
Due to the steepness of the road and the tight turns, heavy vehicles travel slowly, which can lead to a large difference in speeds between light and heavy vehicles.
The project would provide additional lanes and improve the curves. This would increase the safety, capacity and efficiency of the M1 Princes Motorway.
