As an ancient city, Aberdeen maintains historic infrastructure features such as the Brig o' Balgownie and the Bridge of Dee.
The advent of cars since has seen the creation of higher-capacity, modern infrastructure such as the Anderson Drive dual carriageway and the Haudagain Roundabout.
Aberdeen Airport, in the neighbouring town of Dyce, serves primarily UK and European destinations for passenger and freight flights.
For example, the Deeside Railway which ran west of the city to Ballater opened in 1853 but the Beeching Report led to the closure of the line in 1966.
ScotRail services connect Aberdeen to six of the seven other Scottish cities, including Edinburgh and Glasgow, and many intermediate destinations.
A regular stopping service, also run by ScotRail, serves Aberdeen along with all stations between Inverurie and Montrose.
Inter-city services operated by CrossCountry connect Aberdeen to south-west England and numerous intermediate destinations such as Sheffield, Birmingham, Bristol and Exeter.
In addition, the Caledonian Sleeper service makes an overnight journey to/from London Euston six days a week.
Bus services form the main public transportation system in Aberdeen since the closure of the tram network.
First Aberdeen has been criticised by local politicians and in the media for taking advantage of its monopoly with high fares and mediocre service.
[6] The company has defended its frequent fare rises as being necessary due to high running costs and cuts to government subsidies.
[17] For example, route 1 runs from Danestone in the north, to the city centre along Union Street, then out to Garthdee in the south-west.
These services and other Stagecoach buses that start at the bus station also pick up and drop off passengers within the city itself.
Ten Van Hool A330H hydrogen-powered buses were introduced in 2015 as part of a scheme to demonstrate the capabilities of the technology.
[50] The energy company Vattenfall announced, at the beginning of 2022, a proposed demonstrator project to use one of its existing offshore wind turbines to produce hydrogen on the platform itself, and then pipe it to a storage area close to Aberdeen.
Victoria Bridge was completed in 1887, following a ferry disaster in 1876 which claimed the lives of 32 people returning from a visit to the Bay of Nigg.
Wellington Suspension Bridge is very narrow and was designed by Captain Samuel Brown and opened in 1831 to replace the Craiglug ferry.
Refurbished in 1930, the Category A listed building was closed to vehicular traffic in 1984 and to pedestrians in March 2002 due to structural concerns.
Access to the bridge, other than for pedestrians and bicycles, is now controlled by an electronically activated barrier, passes for which are made available to residents of the housing development constructed on the site of the mills in 2004.
Originally, the defective harbour, with a shallow sand and gravel bar at its entrance, retarded the trade of Aberdeen, but under various acts since 1773 it was greatly deepened.
A 1,050 ft (320 m) long concrete breakwater was constructed on the south side of the stream as a protection against south-easterly gales.
