The Guided Bus will provide 'high quality, reliable and frequent' transport along the A14 from Huntingdon in to Cambridge.
Opening early in 2009, the service will run buses along an upgraded derelict railway line from St Ives to Arbury Park in North Cambridge, from where it will run along regular streets to the railway station, Addenbrooke's hospital and on to Trumpington Park & Ride. From St Ives out to Huntingdon it will also run on roads.
