dangerous junction - no visibility
A few years back, the university reopened the Fitzwilliam Gate off the Downing Site, which had been locked and closed for many years. This was to facilitate a one-way system on the site so that vehicles enter via Botany, but leave via Fitzwilliam.
There is a wall which obstructs visibility of drivers exiting - it is very hard to see traffic coming from the Lensfield Road (southern) end of Tennis Court Road. I spent a few minutes chatting to a friend on that corner and we saw several near-misses.
