The Dean Bridge spans the Water of Leith in the city of Edinburgh on the A90 road to Queensferry on the Firth of Forth. It carries the roadway, 447 feet (136 m) long and 39 feet (12 m) broad, on four arches rising 106 feet (32 m) above the river.  The bridge was one of the last major works before retirement of the bridge designer, civil engineer Thomas Telford, and was completed in 1831 when he was seventy-three years old. 
Before the bridge was built the river had been crossed since medieval times at a ford, later by a single-arch stone bridge near the same spot, at the foot of Bell's Brae in the Dean Village. The private Dean Gardens lie under the east side of the bridge on the north bank of the Water of Leith. 
The original proposal for a new bridge came from John Learmonth, a former Edinburgh Lord Provost and owner of the Dean estate on the north bank of the river. Following the successful expansion of the New Town on Lord Moray's estate on the south bank, Learmonth wanted to feu his land on the north side to create a further extension, but needed a more convenient link to the town over the gorge at Randolph Cliff, while also providing an impressive approach to his development. Learmonth was prepared to meet the cost himself, estimated at £18,556, but in 1828 the Cramond Road Trustees, responsible for public roads in the district, agreed to part-fund a new bridge on condition that it would be designed by Britain’s foremost bridge builder and be toll-free. 
The contract was given to Aberdeen builder, John Gibb, with whom Telford had worked on the building of Aberdeen harbour. Work began in 1829 and was completed by the end of 1831. The stone was brought from Craigleith quarry near the village of Blackhall. Weight and cost were saved by building hollow piers, a feature which facilitates their effective inspection today. The footway was carried on outer segmental arches, the wooden supports of which had to be carefully removed, slowly and evenly, to allow the finished bridge to settle uniformly into its final position.  The resident engineer for the Works was Charles Atherton,  who later acted as resident engineer on Telford's Broomielaw Bridge in Glasgow
The bridge was completed at the end of 1831.  Between completion and the contract hand-over date, Gibb had a toll-gate erected at each end of the bridge and charged pedestrians one penny per head to enjoy the view from the structure. The opening date was early in 1832, though the bridge was not opened to horse and cart traffic until May 1834. 
Learmonth died in 1858 before completion of most of his envisaged residential development. Owing to a sudden lull in building, Clarendon Crescent was not built until the 1850s, and Buckingham Terrace, Learmonth Terrace and Belgrave Crescent appeared only in the next decade. 
In 1888, the Edinburgh Corporation asked the Burgh Engineer John Cooper to recommend measures designed to deter suicides which were occurring from the bridge. As a result, the height of the parapet was raised. 
In 1957 the Institution of Civil Engineers, of which Telford was first President, installed a plaque on the east parapet to commemorate his bicentenary. This was subsequently stolen but replaced in 1982. 
The bridge is an important location in the novel "The Lewis Man" by Peter May.
Thomas Telford was a Scottish civil engineer. After establishing himself as an engineer of road and canal projects in Shropshire, he designed numerous infrastructure projects in his native Scotland, as well as harbours and tunnels. Such was his reputation as a prolific designer of highways and related bridges, he was dubbed the Colossus of Roads, and, reflecting his command of all types of civil engineering in the early 19th century, he was elected as the first president of the Institution of Civil Engineers, a post he held for 14 years until his death.
Dean Village is a former village immediately northwest of the city centre of Edinburgh, Scotland. It is bounded by Belford Road to the south and west, Belgrave Crescent Gardens to the north and below the Dean Bridge to the east. It was formerly known as the "Water of Leith Village" and was a successful grain milling area for more than 800 years. At one time there were no fewer than eleven working mills there, driven by water from the Water of Leith.
Modern Two, formerly the Dean Gallery, in Edinburgh, is one of the two buildings housing the Scottish National Gallery of Modern Art, one of Scotland's national art galleries. It is operated by the National Galleries of Scotland. It is twinned with Modern One which lies on the opposite side of Belford Road.
The New Town is a central area of Edinburgh, the capital of Scotland. It was built in stages between 1767 and around 1850, and retains much of its original neo-classical and Georgian period architecture. Its best known street is Princes Street, facing Edinburgh Castle and the Old Town across the geological depression of the former Nor Loch. Together with the West End, the New Town was designated a UNESCO World Heritage Site alongside the Old Town in 1995. The area is also famed for the New Town Gardens, a heritage designation since March 2001.
Canonmills is a district of Edinburgh, the capital of Scotland. It lies to the south east of the Royal Botanic Garden at Inverleith, east of Stockbridge and west of Bellevue, in a low hollow north of Edinburgh's New Town. The area was formerly a loch which was drained in three phases in the 18th and 19th centuries, disappearing finally in 1865.
Ravelston is an affluent area of Edinburgh, Scotland, to the west of the city centre, the east of Corstorphine and Clermiston, the north of Murrayfield, West End and Roseburn and to the south of Queensferry Road.

The area also hosts art festivals and crafts fairs.
James Jardine was a Scottish civil engineer, mathematician and geologist. He was the first person to determine mean sea level. He built tunnels and bridges, including for the Innocent Railway, and built reservoirs including Glencorse, Threipmuir, Harlaw for Edinburgh Water Company, and Cobbinshaw for the Union Canal.

The City Union Bridge is a bridge on the River Clyde in Scotland. It was opened in 1899. It was once a busy main route in and out of St Enoch station but that terminus closed in 1966 and was demolished in 1977, and since then the bridge is only used for empty stock movements, as the bridge forms a key link between Glasgow Queen Street and Glasgow Central. If a project known as Glasgow Crossrail goes ahead then the bridge and associated track will see passenger services once more.
