As many of you have already received information in your letterbox regarding the next major phase to the Armadale Road to North Lake Road Bridge Project. Check the Mainroad website for more project details.
This post will highlight the construction that will impact residents in Calleya Estate and surrounding Treeby. Mainly the Ghostgum Ave entrance to Armadale Road.
This 3-staged construction will commence in early September 2020 and aims to mid-2021. A major diversion is required to assist the widening of Armadale Road. As a result, the intersection will be converted to left-turn access only during the construction phase.
Ghostgum Avenue traffic intending to travel westbound on Armadale Road will be required to turn left at Armadale Road and follow the detour to the Liddelow Road roundabout then turn back onto Armadale Road, adding an extra 2 km, or approximately four minutes to travel times.
Armadale Road westbound traffic intending to travel northbound on Ghostgum Avenue will be required to continue travelling west on Armadale Road to the temporary roundabout at Tapper Road and Verde Drive (in operation from mid-August), then turn back onto Armadale Road. This will add an extra 1.5 km, or approximately three minutes to travel times.
Right turning movements between Armadale Road and Ghostgum Avenue will be prohibited, as they would require road users to cross an active construction site and oncoming traffic, without protection from traffic signals. This would create a potentially hazardous situation for road users and construction workers in the area. This duration of the right turn closure is necessary for the significant works to be safely undertaken in a heavily constrained area with live power, gas and water services.
Signed detours will be in place throughout each stage of the works. A detour map can be found below. To minimise disturbance to residents, we aim to keep construction-related noise to a minimum and will actively monitor these impacts throughout.
Upon completion, an additional lane will be added to the Armadale Road and Ghostgum Avenue intersection in each direction to improve capacity and support ongoing residential development in Treeby.
