Part of Northbourne Avenue whose surface has been cracking. ROADWORKS on arguably one of Canberra’s busiest arterial thoroughfares in the morning peak-hour traffic is set to take seven weeks for completion. The northbound section of Northbourne Avenue will have two of its three lanes shut down on weekdays between 5am and 3pm and on Saturdays between 7am and 4pm to reduce the route that connects the north to the city into a suburban road. One lane will then be closed from mid-afternoon into the early mornings of the next day. The road resurfacing will affect northbound traffic between Greenway Street and Macarthur Avenue from Monday, May 24 until Friday, July 9.
