Strathmore, south of Essendon Airport. Upgrades to the interchange with Calder Freeway were announced in January 2005, which underwent dramatic reconstruction to alleviate congestion. Entry and exit ramps between both freeways were decommissioned and replaced, an additional two lanes inbound were added, with dedicated Bulla Road-Calder Freeway spurs to eliminate weaving, notorious for many accidents in the area; the new inbound lanes towards the city were completed in October 2006 (ten months early), and new outbound lanes towards Melbourne airport were completed in February 2007 (five months early). Another project completed later that year was a new bridge and northern entrance to the Essendon Airport through the interchange of Melrose Drive, to provide easy access for the people living in the northern suburbs to access the Essendon Airport district. Both projects were planned, designed and constructed under an alliance agreement between VicRoads, Baulderstone Hornibrook and Parsons Brinckerhoff.
