When I visited a couple of weeks ago, there were also exhibitions about the proposed new town of Northstowe, which will be on the west side of the busway between Longstanton and Oakington; and about busway wildlife.
Outside the terminal building is a bus stop evidently intended for use by local buses. But so far no other bus routes have been introduced or diverted to connect into the busway at Longstanton. Even Stagecoach's Service 5 which serves Fen Stanton, Fen Drayton, Swavesey, Over and Longstanton does not connect with the busway, although it has potential to do so at both Swavesey and Longstanton Park & Ride.
St Ives Park & Ride should have had a terminal building, but it was cancelled in order to save money on the busway construction project.
