Freeway (between Laverton North and Werribee), the standard travel time is 9 minutes: 6 minutes between the Western Ring Road and Forsyth Road, and 3 minutes between Forsyth Road and Duncans Road. The usual peak period travel time is between 12 and 18 minutes; however, in times of extreme congestion or traffic accidents, the travel time can well exceed 20 minutes. History The Maltby Bypass was Victoria's first freeway which opened on 16 June 1961, and was the first section of Princes Freeway to open. Both sections of Princes Freeway were signed National Route 1, either inheriting it when converted from older sections of Princes Highway, or assigned when newly constructed to bypass a section of it. With Victoria's conversion to the newer alphanumeric system in the late 1990s, the freeway's National Route 1 designation began conversion to M1 in late 1996, and was completed in 1997. Former bypassed sections of Princes Highway are generally signed as Metropolitan Route 83 or route C109 (western section), Alternative National Route 1 or designated successive routes from C101 to C104 (eastern section). The passing of the Road Management Act 2004 granted the responsibility of overall management and development of Victoria's major arterial roads to VicRoads: in 2012, VicRoads re-declared the western section as Princes Freeway West (Freeway #1500) from Corio-Waurn Ponds Road in Highton to Little Boundary Road at Laverton North (this definition includes Geelong Ring Road, and in 2007, VicRoads re-declared the eastern section as Princes Freeway East (Freeway #1510) from Monash Freeway at Narre Warren to the eastern end of Princes Drive in Morwell (minus the highway section between Yarragon and Trafalgar). VicRoads also classifies a 5km stretch of road between Newmerella and Orbost as part of Princes Freeway East, despite being a two-lane, single-carriageway road and signed as Princes Highway. In March 2010 it was announced by the State Government that trucks would be banned from the right-hand lane along a section of freeway between Geelong and Melbourne. Suggestions of a ban began in 2005 but increased after the fatal 2007 Burnley Tunnel fire that killed three people. The ban was put into place from 1 July 2010 between Kororoit Creek Road, Altona, and Avalon Road, Lara and covers all heavy vehicles weighing more than , except buses and caravans. A fine of $358 applies to those breaking the rules, the ban being a trial before a full roll-out on
