PART of Hepburn Ave will close next year while construction of the central section of NorthLink WA continues.
Main Roads WA said NorthLink WA central section will extend Tonkin Hwy to the north with a flyover at Marshall Rd and a new interchange at Hepburn Ave-Beechboro Road North. Construction is now underway.
To allow these works to be completed Hepburn Ave will be closed between Pass Way and Marshall Rd from early next year.
It will re-open to traffic as part of the newly-upgraded Tonkin Hwy when NorthLink WA is finished by mid-2019.
In an alert Main Roads WA said the closure of Hepburn Ave would allow safe construction of the interchange, flyover and dual carriageways for Tonkin Hwy and minimise inconvenience to motorists throughout the works by allowing for a more consistent staging approach.
“Before closing Hepburn Ave in early 2018, we will upgrade the surrounding road network,’’ Main Roads WA said.
The following intersections will be upgraded Pass Way- Beechboro Road North roundabout in Whiteman.
“The roundabout will widen to two lanes, allowing more traffic to flow through during the morning and afternoon peak periods.’’
The Beechboro Road North-Marshall Road intersection in Bennett Springs will be upgraded with additional through and turning lanes, and reconfigured traffic signals.
“Some lane closures and speed limit reductions will be in place during these works, which are expected to be complete by early 2018.”
From Wednesday, December 6 to Saturday, December 16 morning as part of the works to upgrade the Altone Rd intersection, Reid Hwy will be reduced to a single lane in both directions from 8pm.
“Traffic will then be moved into a contra-flow arrangement with stop-go traffic control in place from 10pm to 5am, finishing on Saturday morning December 16.”
Main Roads WA advised motorists to plan ahead and allow extra travel time as speed limits would be reduced in the construction zone.
