Maybury Road is nominally a 40mph road however a brief observation period will quickly reveal many drivers going at 60mph or more. This is not a suitable speed for a high use cycle route. The pavements are badly maintained and yet still used by the majority of cyclists using the road, especially uphill in either direction.
The traffic lights at either end of the road only ever allow one lane of traffic onto the road at a time which encourages drivers to overtake each other at high speed.
A two way cycle route should be built the length of the road taking the space currently allocated to the uphill lane in either direction. The earlier removal of the southbound uphill section illustrates the redundancy of the extra lane nicely.
