The 29 locks have a rise of 237 feet in 2 miles (72 m in 3.2 km) or a 1 in 44 gradient. The locks come in three groups. The lower seven locks, Foxhangers Wharf Lock to Foxhangers Bridge Lock, are spread over ¾ of a mile (1.2 km). The next sixteen locks form a steep flight in a straight line up the hillside and are designated as a scheduled monument. Because of the steepness of the terrain, the pounds between these locks are very short. As a result, 15 locks have unusually large sideways-extended pounds, to store the water needed to operate them. A final six locks take the canal into Devizes.

This flight of locks was engineer John Rennie's solution to climbing the very steep hill, and was the last part of the 87-mile route of the canal to be completed. Whilst the locks were under construction a tramroad provided a link between the canal at Foxhangers to Devizes, the remains of which can be seen in the towpath arches in the road bridges over the canal. A brickyard was dug to the south of the workings to manufacture the bricks for the lock chambers and this remained in commercial use until the middle of the 20th century.

Because a large volume of water is needed for the locks to operate, a back pump was installed at Foxhangers in 1996 capable of returning 7 million gallons of water per day to the top of the flight, which is equivalent to one lockful every eleven minutes.

In the early 19th century, 1829–43, the flight was lit by gas lights.

The locks take 5–6 hours to traverse in a boat and lock 41 is the narrowest on the canal.

After the coming of the railways, the canal fell into disuse and was closed. The last cargo through the flight was a consignment of grain conveyed from Avonmouth to Newbury in October 1948. From the 1960s there was a major clearing and rebuilding operation, culminating in a visit by Queen Elizabeth II in 1990 to open the new locks officially, although the flight had been navigable for a number of years before then.

In 2010 British Waterways planned to install sixteen new locks gates in twelve weeks as part of its winter maintenance programme, in an attempt to reduce the amount of water lost. The exceptionally cold weather delayed work, and when the section was re-opened at Easter 2010 only twelve pairs of gates had been dealt with. The wood from the old gates was donated to Glastonbury Festival and used to build a new bridge which was named in honour of Arabella Churchill, one of the festival's founders.
