Stage 2 - Mona Vale Road East upgrade - Manor Road to Foley Street

Updates and announcements

Roads and Maritime Service will continue geotechnical and utility investigation day work until the end of June. View or download the notification (PDF, 287Kb)

Our working hours will be 7am to 6pm, Monday to Friday, weather permitting.

Survey work will be carried out until the end of August along Mona Vale Road from Manor Road to Foley Street.

Our working hours will mostly be from 7am to 6pm, Monday to Friday, weather permitting.

There will also be up to 20 night shifts of geotechnical and survey work in June and July between 6pm to 7am, Monday to Friday, weather permitting. Information from this survey work will be used to inform the detailed design for the section of Mona Vale Road from Manor Road to Foley Street.

We will continue to keep you informed at key stages of the project.

Project background

The NSW Government is planning to upgrade Mona Vale Road from two lanes to four lanes between Terrey Hills and Mona Vale. The project will be staged to provide customers with a better travelling experience and to improve safety and traffic efficiency.

Mona Vale Road East currently experiences congestion as a result of the steep grade and limited safe vehicle overtaking opportunities which increases travel times. The proposed road upgrade for Mona Vale Road East would provide:

  • Additional lanes for climbing and descending to improve travel time in both directions
  • Widened shoulders and median separation to improve safety
  • 80km/h speed limit between Mona Vale and Belrose once the road upgrades for both Mona Vale Road East and Mona Vale Road West are completed
  • Facilities for cyclists and pedestrians
  • Bus priority measures.

What is happening now?

Roads and Maritime prepared a Review of Environmental Factors (REF) to examine the potential impacts of the proposed upgrade to Mona Vale Road East and outline measures to reduce and manage the impacts. The REF was displayed for community and stakeholder comment from Wednesday 29 July to Friday 28 August 2015.

We received a total of 156 submissions in response to the display of the REF including four submissions from government agencies or advisory bodies. The remainder were from members of the community and interest groups.

Roads and Maritime has prepared a Submissions Report which responds to the matters the community and stakeholders raised. The report also provides additional information about design refinements proposed to the displayed REF. The common points that the community and interest groups raised are outlined below.

  • Changing the Emma Street intersection to left turn in and left turn out only
  • Location of the truck arrester bed
  • Fauna connectivity
  • Changing the posted speed limit from 70 km/h to 80 km/h once the proposal and the Mona Vale Road West upgrade have been completed
  • Implementing a 60 km/h truck and bus speed limit for the downhill descent from near Ingleside Road to base of the escarpment
  • The left-turn lane from Mona Vale Road into Samuel Street as part of the proposed widening and upgrade to the intersection of Ponderosa Parade and Samuel Street
  • Changes to Samuel Street including installation of a concrete median
  • Cycling and horse riding provisions
  • Property impacts including access and partial acquisition
  • Environmental mitigation measures
  • Road traffic noise impacts and mitigation measures.

Next steps

Roads and Maritime has determined the Review of Environmental Factors for Mona Vale Road East and is proceeding with the detailed design phase of the project.

Roads and Maritime is currently preparing the REF for Mona Vale Road West. The report provides detailed information on the proposed concept road designs, environmental impacts and mitigation measures to minimise these impacts. The REF will be placed on display for public comment in the first half of 2016.

What road upgrades are being proposed?

Roads and Maritime has developed a concept design for Mona Vale Road East which includes upgrading the 3.2 kilometres of Mona Vale Road between Manor Road/Lane Cove Road, Ingleside and Foley Street, Mona Vale from a two lane undivided road (one lane in each direction) to a four lane divided road (two lanes in each direction). We plan to locate the majority of the widening on the northern side of Mona Vale Road. There would be a number of deep cuts and tall retaining walls as part of the road upgrades due to the local terrain.

The key features of the proposed upgrade would include:

  • Widening Mona Vale Road between Manor Road and Foley Street from two lanes to four lanes with a central concrete safety barrier. The concrete safety barrier would be located east of Manor Road to west of Daydream Street
  • Providing three metre wide shoulders along the length of Mona Vale Road between Manor Road and Foley Street to allow a safer area for breakdowns and on-road cyclists
  • Replacing the existing roundabout on Mona Vale Road at the intersection of Ponderosa Parade and Samuel Street with new traffic lights and signalised pedestrian crossings on all legs
  • Providing new bus priority lanes on Mona Vale Road on the approaches to and departures from the intersection of Ponderosa Parade and Samuel Street
  • Relocating the eastbound bus stop on Mona Vale Road near the Ponderosa Parade and Samuel Street intersection further east to the departure side of the intersection
  • Upgrading and widening the existing signalised T-intersection at Foley Street and Mona Vale Road to provide a westbound left turn lane into Foley Street and a westbound left turn lane out of Foley Street
  • Providing a three metre wide shared path along the southern side of Mona Vale Road between Foley Street and Ponderosa Parade for pedestrians and cyclists
  • Providing additional off-road connectivity for pedestrians and cyclists away from the Mona Vale Road corridor due to the steep descent from the Warriewood Escarpment. This would be provided via the path along Lane Cove Road that links to Mona Vale Road near Walana Crescent
  • Duplicating an existing culvert to provide fauna connectivity at the end of Lane Cove Road near Narrabeen Creek
  • Changing the speed limit from 70km/h to 80 km/h once the road upgrades for both Mona Vale Road East and Mona Vale Road West have been completed
  • Implementing a 60km/h truck and bus speed limit for the downhill descent from Ingleside Road to the base of the escarpment
  • Providing a truck arrester bed, about 150 metres long, for eastbound vehicles next to Walana Crescent
  • Making the Emma Street intersection left turn in and left turn out only
  • Building six fill retaining walls up to six metres in height and five cuttings up to 16 metres in height along the length of Mona Vale Road due to the local terrain
  • Upgrading the existing road and cross drainage systems including the construction, reconstruction and extension of the road drainage network
  • Establishing temporary site compounds and stockpiles during construction
  • Landscaping over the length of the proposal
  • Installing traffic monitoring cameras at all signalised intersections to assist with traffic management
  • Relocating utilities where required and providing a utility corridor away from Mona Vale Road along Lane Cove Road.
