The access to Chaucer's Lane/Harrison's Lane from Park Street is a "no through road", Cars looking for parking spaces in Woodstock drive up Park Street and then turn round by in the large open area by the Blenheim Town Gate. When they drive back they see the entrance to Chaucer's Lane (see image) and because there is no visible dead end sign they often drive down and into Harrison's Lane. They then see the no entry signs and have to do three or four point turns to get back to Park Street. This happens several times a day. There is a small sign on the left hand side (which they don't see) and something needs to be put up on the right hand side to deal with this problem.
