with grand unions, double-track to double-track junctions, where trams could go to all directions from all directions. These junctions were at the intersections with Customs Street and Wellesley Street. Since the closure of Auckland's tram network, Balaclava Junction on Melbourne's tram network has been the sole grand union left in the Southern Hemisphere. 2006—2008 upgrade Public perception in the early 2000s was that Queen Street had lost some of its good reputation in the previous decades, with a rundown and uncoordinated streetscape and the loss of several prestigious retailers cited as either causes or effects. Auckland City Council decided to address the issue of the 'tired' Queen Street through a major redevelopment of the street. This involved the widening and relaying of footpaths with basalt kerbstones and paving. Granite insets, designed in consultation with the local Māori (Ngati Whatua iwi), as well as recycled redchip pavers from the existing footpath, were used to denote special areas – such as those related to the existence of the old Waihorotiu Stream. New street furniture (such as multi-purpose poles for lighting, signage and pennants) and new trees and other landscaping were added to create a 'boulevard effect'. The liquidambars and Nikau Palms chosen for the new design touched off heated public discussion in 2006 as their inclusion came at the destruction of previous, established trees (which were not native flora of New Zealand, and thus not retained in the new landscaping plan). The 2006–2008 project repeatedly increased in cost, from NZ$23 million to around NZ$43.5 million, with some aspects (such as an improved entrance to Myers Park) falling victim to the blowout. While Council noted in June 2007 that progress had often been quicker than expected, the cost overruns, and the long duration of the construction works – which substantially affected pedestrian and motor vehicle traffic as well as retail sales – made the upgrade unpopular in public, at least during the duration. It also became a problem issue for Dick Hubbard in his failed campaign for re-election to Mayor of Auckland in 2007. The upgrade is now considered to have generally been a success, and it won the 2009 Urban Design Award of the New Zealand Institute of Architects, which commended it for creating a quality public realm and sense of place. Upgrade priorities To accommodate construction work, Auckland City Council reduced traffic lanes for vehicles to one lane in each direction
