Yes, Worcester could also do with a second city centre road bridge. However, this WOULD cause an additional bottleneck near the racecourse, and make the road layouts very complicated. The Southern bypass bridge is too narrow for a dual carriageway. Therefore I think the priority must be for a new road from Rushwick to Claines (the remaining gap). It must be dual carriageway standard, with 2 lanes crossing the Severn. After this, the next priority must be dualling the remaining part of the ring road.
A new bridge in central Worcester from McDonald's to the Severn View Hotel is planned by the Council which is actually on the site of a former bridge. In the main it is designed to replace the existing bridge - They are talking about pedestrian use east bound and bus lane and cars from Deansway westbound. The new bridge would then easily handle traffic to and from Castle Street.
The Southern bypass bridge is only single carriageway, Worcester CC could not afford a dual carriageway version and so the roads to the bridge in both directions were only built as single despite owning enough land in order to make dual. It was found impossible to build a bridge there that could be widened at a later date and so to get a dual carriageway bridge the current bridge will need to be replaced at an impossible cost.
I agree the only option now to reduce the traffic is to build the northern bypass, but no doubt, the pot will not be big enough for a dual carriageway river bridge.
Do LM▸ actually have proper plans for a set of points? I would have thought that the signalling would have to change so much, it would not be considered until after the resignalling.
There are, I believe, a set of rough plans and costings running around which London Midland are doing the maths on, although the overall picture includes looking at the timetable post Bromsgrove. The existing signaling used to have this layout so it is considered possible to put it back without too much difficulty. So the ball is in London Midlands court as to whether it will be useful enough to be worth the cost, but as has already been mentioned, Worcester is at the edge of London Midland's area and not that important.
Other than this, and given that all government money seems likely to be spent on electrification a long way from Worcester, the only hope for change is the planned resignaling when the existing layout will be changed. But don't hold your breath for when that will take place, current plans to put Worcester's signaling system into Satley, Birmingham in around 2020ish are very liable for change / putting back / or abandonment. There is a growing realisation that Worcester may well be the last place in the country with
GWR▸ signals outside the preservation movement.
