They seem to work from 7am to early afternoon Monday to Friday and Saturday mornings. Tomorrow sees the start of a 7 week closure of the link road from Airport Way to Gypsy Lane. This means that the shuttle bus to the station has got to do a major detour to get from the airport to the station.
The problem from day one has been the lack of guys actually building the road and with a recession in the construction trade I guess they are in no hurry to finish the job.
