In 1956 the Grimsby company introduced the first one-person operated service on its Corporation Road route 1, using new twin entrance single deckers. In 1957 both councils merged their bus companies to form Grimsby-Cleethorpes Transport, run by a joint committee. The crimson/cream livery of Grimsby and the blue/grey colours of Cleethorpes were replaced with the blue and cream of the new company. The Cleethorpes depot at Pelham Road was closed down, the buses and staff moving to the Grimsby depot in Victoria Street.
