little fanfare in the late 1998s, leading to increased use of the road, mostly to semi-trailers and heavy freight to get to the docks in the Westernport district (Dandenong-Hastings Road was yet again renamed the Western Port Highway to reflect this and was eventually duplicated). Traffic levels dropped substantially when the Hallam bypass opened in 2003; the South Gippsland Freeway was extended back to its original terminus in Doveton at a new junction with the Monash Freeway. In 2010, the Pound Road half-diamond interchange was substantially upgraded with a new four-lane carriageway being constructed over the freeway, the addition of traffic lights to the on-ramp intersection, and ramp metering signals. These works were completed late 2011. In recent years, the freeway has become very busy, carrying high volumes of traffic off the South Gippsland Highway, Western Port Highway and the Pound Road and Princes Highway on-ramps. The freeway attracts all these vehicles, a large proportion of which are freight (hence two ramp metering sites inbound have a priority lane), due to the Monash Freeway which connects to it, being the major south-east freeway leading to Melbourne City. It is also the only freeway (or non-tollway, such as EastLink) to the city. It has led to slow or heavy traffic (inbound) during the morning peak and gets even more congested when the Monash Freeway is already heavy. Outbound is not so bad, although when very heavy traffic comes off the Monash Freeway (outbound), it can cause a bottleneck near and around the Princes Highway interchange, so a ramp signal site was installed to meter out traffic and reduce flow breakdown. So, as part of the major 2007 M1 (Monash-CityLink-WestGate) Upgrade; which included widening to more lanes, updates to safety, electronic drive time signs and associated arterial road real-time information signs and a freeway management system with ramp metering (key component). The freeway was also upgraded to include a Freeway Management System, from its start at the South Gippsland Highway interchange to the Monash Freeway junction. It added Ramp Metering signals to the South Gippsland Freeway / Pound Road / Princes Hwy (inbound) on-ramps (the outbound on-ramp already had an existing metering site). With this, it also included electronic real-time information signs on the three inbound on-ramps, showing travel times and flow conditions downstream from that respective location to either destinations on the Monash Freeway and/or South Gippsland Freeway. Therefore, it also
