CHANGES are being made in May to bus services in West Devon and East Cornwall by operator First, to further streamline its network. Starting on Sunday, May 25, there will be a restructuring of the services operating between Plymouth and Tavistock which will include a direct service linking the two. Alex Carter, managing director for First Devon and Cornwall, said: 'The changes are to improve the attractiveness and efficiency of our services. 'Feedback from customers has been crucial to making decisions about some of the routes. 'We have taken great care to ensure that the service changes reflect their usage and that all the local communities in the area continue to have regular and reliable bus services.'
