[2] In 1927, Grimsby Corporation Transport bought its first motor buses, these being centre entrance single deck Albions.

[4] However, Cleethorpes' department's managing director was initially opposed to the plan, and so discussions continued until an agreement was made in 1957.

[5][6] Both councils then merged their bus companies to form Grimsby-Cleethorpes Transport (GCT), run by a joint committee.

Later dual-door Fleetlines were acquired and these were used to gradually extend the one-person operated bus system to the double deck routes.

RoadCar began running buses from Grimsby town centre to the Grange, Nunsthorpe and Bradley Park estates, areas previously served only by GCT.

The Garden Street premises was briefly used for the storage of old buses before being put up for sale in 2008,[citation needed] where in that same year, Stagecoach closed its Louth depot and transferred operations of Louth-area routes over to Grimsby-Cleethorpes.

[13][14] On 6 October 2002, arsonists started a fire at the Victoria Street bus depot, damaging or destroying 17 buses.

[15] In 2006, Stagecoach Grimsby-Cleethorpes received £522,677 of funding from the Department for Transport's 'Kickstart' initiative to improve local bus services, with further financial support also acquired from North East Lincolnshire Council.

[16] Circular routes 3F and 4, operating from Cleethorpes Pier to Bradley Cross Roads, were renumbered as 13 and 14 and saw a bus frequency increase alongside the introduction of new low-floor buses.

Between 2005 and 2006, the service faced the threat of being axed due to cost issues connected to the toll payments for crossing the Humber Bridge.

The service operated via Weelsby Road and Cleethorpes Seafront, to terminate at Pleasure Island Theme Park.

Dedicated branded vehicles were introduced to the route in February 2015, with four Alexander Dennis Enviro300s gaining a blue-based 'Humber Flyer' livery.

[22] Stagecoach Grimsby-Cleethorpes are contracted by North East Lincolnshire Council to run the 'Phone 'n' Ride' demand-responsive transport service.
