Mona Vale Road East Upgrade

The Mona Vale Road East upgrade is a significant infrastructure project transforming a key 3.2-kilometre stretch of this vital route in Northern Sydney. The NSW Government’s $140 million investment aims to enhance safety, reduce congestion, and improve overall travel experiences between Manor Road, Ingleside, and Foley Street, Mona Vale. With an expected completion in 2024, the project is well underway, and Danterr is proud to support it by supplying essential construction materials.

The Problem: Congestion and Safety Concerns

Mona Vale Road East, in its previous two-lane configuration, struggled with significant bottlenecks and safety risks. The steep grade and lack of overtaking opportunities resulted in frustratingly long travel times and traffic backups. Additionally, the absence of a separated median and narrow shoulders posed safety hazards for drivers, cyclists, and pedestrians alike.

The Solution:  A Comprehensive Road Upgrade

Mona Vale Road Upgrade

The Mona Vale Road East upgrade tackles these issues head-on with a multi-faceted approach:

  • Widening and Safety Enhancements: The road is being widened from two to four lanes with a central concrete safety barrier, significantly improving traffic flow and reducing potential head-on collisions. Wider shoulders provide safer spaces for breakdowns and on-road cyclists.
  • Intersection Upgrade: The roundabout at Ponderosa Parade and Samuel Street is being replaced with traffic lights and pedestrian crossings, improving traffic management and pedestrian safety.
  • Focus on Accessibility: New bus priority lanes, along with a 3-meter-wide shared path on both sides of the road, cater to the needs of public transport users, cyclists, and pedestrians.
  • Speed Adjustments: Once complete, the speed limit will increase from 70km/h to 80km/h. Importantly, a 40km/h speed limit for trucks and buses on the downhill descent enhances safety on this steep section.
  • Essential Infrastructure: The upgrade includes a truck arrester bed for eastbound traffic, upgraded drainage, fauna connectivity measures, retaining walls, and landscaping.

Benefits for the Community

The Mona Vale Road East upgrade delivers numerous benefits to residents, businesses, and visitors to the region:

  • Safer Journeys: Enhanced lane separation, pedestrian crossings, the truck arrester bed, and wider shoulders significantly improve safety for everyone using the road.
  • Reduced Travel Times: Additional lanes and optimised traffic flow cut down travel times for commuters and freight transport, boosting productivity.
  • Better Accessibility: Dedicated bus lanes, shared paths, and safer intersections create a more welcoming road for cyclists, pedestrians, and public transport users.
  • Environmental Considerations: Fauna connectivity measures help protect the area’s wildlife.

Danterr’s Contributions: Enabling a Successful Project

Danterr plays a crucial role in the Mona Vale Road East upgrade by supplying essential, high-quality materials:

  • VOIDX™ Void Forming Material:  This innovative product creates voids beneath the road’s concrete slab, minimising damage from shifting soil conditions. This ensures long-term structural integrity and reduces future maintenance costs.
  • BITUTHENE® 5000: This specialised waterproofing membrane shields the new asphalt surfaces from water damage, extending the road’s lifespan and preventing costly repairs.
  • CONNOLLY EXPANSION JOINTS: These joints accommodate concrete expansion and contraction caused by temperature changes.  This helps prevent cracks, potholes, and other damage, leading to a smoother, safer driving experience for years to come.
