In July 2020, Georgiou delivered the $28.7 million Karel Avenue Upgrade for Main Roads WA, a congestion-busting project that will improve safety along a route travelled by almost 20,000 motorists daily.

Scope of works for the project include:

  • widening Karel Avenue bridge over Roe Highway to create a dual carriageway, connecting at the two-lane dog-bone roundabouts for on and off-ramps;
  • extending of above bridge across the freight railway line located immediately south of Roe Highway to facilitate construction of the Thornlie-Cockburn Link as part of METRONET;
  • extending the existing underpass to accommodate the widening;
  • modifying the existing Training Place intersection to left-in and left-out to promote safe access;
  • road widening between the Farrington Road intersection and Roe Highway to four lanes; and
  • road widening between Roe Highway and the Berrigan Drive roundabout to a four-lane dual carriageway, including modifications to the roundabout approaches to enable two lanes in each direction

Georgiou was awarded the design and construction contract in June 2019, following a competitive tender process.

Construction, which employed 50 personnel on-site at peak, commenced in July 2019 and was completed in 2021.
