Plymouth's transport links when the airport closes
As well as having pretty mediocre rail links, Plymouth also has NO motorway. It is incredibly isolated for its size. Government policy is to build high speed train corridors North and when they do go west they usually go along the M4 corridor to Bristol, Cardiff and Swansea. Add to this APD taxes - for some regions air travel is the only viable option and the peripheral nature of Devon and Cornwall is only going to get worse.
