Proposal
We're inviting comment on the road proposal options to resolve the required layout and traffic control requirement for the intersection at Bayeux Avenue and Grand Ocean Boulevard in Port Kennedy. Upgrade of the intersection is required as a result of the Kennedy Bay development, which will connect through to Bayeux Avenue.
A total of six initial options were the subject of preliminary assessment, which identified two viable options for consideration. The six initial options are outlined within the PJAs Technical Note - Bayeux Avenue Intersection Report (attached below).
Description of the Proposal Options
The proposed Intersection Treatment Options presented are:
Both options may require a 3 m widening of the Bayeux Avenue road reserve, encroaching into Bayeux Reserve, to accommodate the preferred road configuration under State policy. Further details on the proposals are provided below:
Option 1: Raised Platform
Raised Safety Platforms (RSPs) are elevated sections of road that aim to reduce vehicle speeds on the approach to areas of higher risk, such as intersections. RSPs are like speed humps, but having a much gentler gradient (ramp slope) means they can be safely used in higher speed environments.
The raised platform is the least disruptive option in terms of physical construction and according to the traffic report, performs as well as the roundabout design in terms of facilitating vehicle movement through the interaction
Option 2: 7 m Roundabout
The proposed roundabout is required to be consistent with the Aus Road Guidelines, providing a minimum 7 m radius with deflections to slow traffic movement.
A roundabout would take up additional space, encroaching upon the corner of Bayeux Reserve and requiring the relocation of services at that location. A roundabout may also impact upon access to adjacent properties.
Bayeux Avenue Road Widening
It is estimated approximately 6,000 vehicles per day will travel north from the Kennedy Bay Structure Plan and use the Bayeux Avenue and Grand Ocean Boulevard intersection by 2041. As outlined in the State’s Liveable Neighbourhoods Policy, a ‘Neighbourhood Connector A’ profile is recommended consistent with the road profile proposed for the Neighbourhood Connector A/B Hybrid Typical Cross Section (17 m).
The widening of the Bayeux Avenue road profile is still under consideration and comments are sought as part of the Road Treatment Proposal. The current road reserve width of Bayeux Avenue has a 14 m wide road reserve with a 7 m carriageway, allowing for 3.5 m lanes in each direction.
Widening of the Bayeux Avenue road reserve to 17 m would require the removal of the majority, if not all, the trees on the northern side of Bayeux Reserve.
