On Park Road going west-bound after the hospital/university, the right-hand lane has a "straight-ahead" arrow painted on it just after Seafield View Road. Left-hand lane is a bus lane. About 5 metres (!) before the intersection with Grafton Road, suddenly the right-hand lane is right-turn only, and the left-hand lane is left-turn and straight-ahead. There are no arrows painted between Seafield View Road and Grafton Road. Please provide some more advanced warning of lane changes (eg. a lane guidance sign, or repainting the "straight-ahead" arrow just after Seafield View Road as a "right-turn" arrow).
Grafton bridge being bus/bike-only most of the time should not excuse such misleading lane markings.
