If you haven't seen it before, this is the Tilehurst Road entrance. In my professional opinion, this is the end where most of the Anti Social Behaviour takes place. In part because it is quite a lengthy walk down from the Tilehurst Road, and in part because it is far way from the main part of the station. It is also rather well covered by the tree's and the fencing / lighting is pretty poor. All in all, it makes for a pretty grim path to walk down. I've had numerous calls over the years to this end of the station, so should be in the priority list.
The Oxford Road certainly is busy - it can often be a bit of a nightmare to drive along, with the volume of traffic, speed humps, poor road condition and number of crossing points all not helping. Something I fear that, by narrowing the road under the bridge, will be made worse by this proposal. What Reading Borough Council really needs to do is find a better way to divert some of the sheer volume of traffic away from the Oxford Road, be-it improvements to the Tilehurst Road or sending more traffic via Cow Lane / Richfield Avenue & the duel carriageway Caversham Road, but that's for a different thread.
On the council planning website there is a map of the site which has an insert at the bottom right showing the Tilehurst Road entrance which is labelled "Tilehurst Rd Gateline [Permitted Development]" - does that imply it will have barriers?
