The Merchant Square Footbridge (also known as The Fan Bridge) is a moveable pedestrian bridge spanning a canal in Paddington, London. It is composed of five side-by side sections of varying lengths, with offset pivots to accommodate the varying lengths. When opened, the segments are brought to varying angles of elevation.
The narrow section at mid-span gives the bridge profile a slight arch shape making this design particularly useful when large headroom is required. The profile also makes the bridge more architecturally pleasing than a beam bridge. Rigid-frame design may be the most efficient bridge type for spans between 35 and 80 feet (11 and 24 m). [5]
Amersham Prefab (COAM)-front room showing solid-fuel fire Prefabs were aimed at families, and typically had an entrance hall, two bedrooms (parents and children), a bathroom (a room with a bath) — which was a novel innovation for many Britons at that time, a separate toilet, a living room and an equipped (not fitted in the modern sense) kitchen.
A Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed in 1940–1941 by the British for military use during the Second World War and saw extensive use by British, Canadian and American military engineering units. A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble.

The Luten arch improves upon preceding concrete arch designs by strategic use of reinforcement where needed to address tension of load upon the bridge. This enables bridges to be considerably lighter. [citation needed] The Luten Bridge Company was one seller of the designs. The Topeka Bridge & Iron Co. was a western seller of the designs. [1]: 3
Thousands of orthotropic deck bridges are in existence throughout the world. Despite the savings and advantages (up to 25% of total bridge mass can be saved by reducing deck weight, as the weight reductions extend to cables, towers, piers, anchorages, and so forth), the US has only about 60 such bridge decks in use as of late 2005.
Rapid bridge replacement or accelerated bridge construction (ABC) is a technique that allows bridges to be replaced with minimum disruption to traffic. The replacement bridge is constructed on a site near the bridge to be replaced. When it is completed, the old bridge is cut away and removed using self-propelled modular transporters (SPMTs).
