and Laverton. 2008-11 upgrade Traffic volumes on the West Gate Freeway have grown steadily since opening, carrying up to 180,000 vehicles every day. Congestion frequently occurs at the Montague Street and Bolte Bridge interchanges due to conflicting traffic movements on and off the freeway. On 1 May 2008 the Minister for Roads and Ports Tim Pallas announced design details for the West Gate Freeway improvements, to assist in maintaining rapidly growing volume capacity and to reduce congestion They are: a full freeway management system, made up of Ramp Metering (Signalling), Lane Use Management Signs (overhead lane availability / variable speed zones), electronic on-road message signs, arterial road message signs, CCTV cameras and a suite of freeway traffic algorithms and software with data stations, thousands of sensors and a core server at the VicRoads TMC. the addition of a new elevated road structure joining the outbound Kings Way on-ramp to the Freeway new traffic ramps over Montague Street an additional dedicated exit ramp from the Bolte Bridge to the Freeway widening of the freeway between Todd Road and Montague Street redesign of the Montague Street interchange. These works help reduce merging and weaving movements at key points on the freeway, leading to a smoother traffic flow and improved driver safety. As part of the works the Montague Street on-ramp city bound had been closed for approximately 18 months to enable the new one to be built. Early works on the West Gate Freeway, including geo-technical investigations and service proving, commenced in late 2007. In early 2008 construction works started on the freeway widening, specifically in the South Melbourne area. New traffic lanes and ramps have been completed and opened in different stages with the total project eventually completed and opened to traffic in June 2011. The project was awarded the 2011 Australian Construction Achievement Award.
