The Mona Vale Road East upgrade is a landmark infrastructure project that has transformed a key 3.2-kilometre stretch of this vital route in Northern Sydney. The NSW Government’s $140 million investment has enhanced safety, reduced congestion and improved overall travel experiences along Mona Vale Road between Manor Road, Ingleside and Foley Street, Mona Vale. The upgraded section opened to traffic in March 2024 and is fully operational, giving road users a smoother and more reliable travel experience.
The Problem: Congestion and Safety Concerns
Previously, Mona Vale Road East operated as a narrow two-lane route, which frequently created bottlenecks and safety risks. The steep gradients and absence of safe overtaking opportunities led to lengthy delays and traffic backups. In addition, the lack of a central median and the narrow shoulders posed hazards for drivers, cyclists and pedestrians.
The Solution: A Comprehensive Road Upgrade
This upgrade tackled those problems head-on with a multifaceted approach:
-
Widening and Safety Enhancements: The road has been widened from two to four lanes and includes a central concrete safety barrier, significantly improving traffic flow and reducing head-on collision risk. Wider shoulders now present safer spaces for breakdowns and on-road cyclists.
-
Intersection Upgrade: The roundabout at Ponderosa Parade and Samuel Street has been replaced with traffic lights and pedestrian crossings to improve traffic management and pedestrian safety.
-
Accessibility for Diverse Users: New bus-priority lanes and a 3-metre-wide shared path on both sides of the road now cater to public transport users, walkers and cyclists.
-
Speed and Traffic Management: The improved alignment supports a higher speed limit of 80 km/h, while a 40 km/h limit for heavy vehicles on the downhill descent improves safety in steep sections.
-
Essential Infrastructure: Additional features include a truck arrester bed for eastbound traffic, upgraded drainage systems, fauna connectivity enhancements, retaining walls and landscape works.
