Small swing bridges as found over narrow canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. Many inner cities have swing bridges, since these require less street space than other types of bridges. (A "swing bridge" in New Zealand refers to

2211-520: The swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. In its closed position, a swing bridge carrying a road or railway over a river or canal , for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however,

A section connected to the bridge remains, and the isolated easternmost plinth and lamppost can still be seen near the corner of Market Street and Sussex Street. In 1980, the eastern end of the bridge was initially connected via a ramp to the viaduct leading north to King Street, but this

The Pyrmont Bridge was re-opened to pedestrian traffic in 1988. Following the end of the monorail's 25 years of operation in July 2013, the monorail track was removed from the bridge. Some changes that had been made to the bridge during the construction of the monorail were then reversed, including

In addition to featuring the lowest maximum summer temperatures in the Sydney region (averaging just 24.4 °C (75.9 °F)), Port Jackson is also least affected by extreme heat due to frequent sea breezes . Conversely, winter nights are among the warmest in Sydney, and rarely dip below 8.0 °C (46.4 °F), although fog often occurs and may be disruptive. Port Jackson's weather station
