The Mickleham Road interchange was struggling to cope with current demand of traffic in the area. Heavy weaving and a high volume of merges at the entry ramps were casuing congestion in peak hours with the entry from Mickleham Road sometimes backing up for kilometres. VicRoads have upgraded the interchange to reduce weaving and ease congestion and this will also make it easier for drivers to access the Tullamarine Freeway. This will ultimately help the interchange cope with current and future demand. It has also provided more reliable travel times for local residents and those accessing the airport.
