The AEC Bridgemaster was introduced by AEC in 1956 to meet the demand of low-height double-deckers from municipal and independent bus operators across the United Kingdom, which were barred from purchasing the Bristol Lodekka.

It was designed as a fully-integral vehicle, utilising two sub frames like the contemporary Routemaster.

[2] In 1960 a forward-entrance version with slightly different driveline layout was introduced.

[3] A total of 180 were produced before it was superseded by the AEC Renown in 1963.

[4] East Yorkshire Motor Services were the largest customer, purchasing 50.
