Talk:A30 road

Old route turned into a cycle lane?
Most certainly not, at least not the infamous section with the iron bridge - I was on holiday in Cornwall last week and became lost on the old road looking for a backstreets route to the Eden Project! It is most definitely still open, though downgraded to a very high standard B or unclassified route (unsure - part of the reason for getting lost was that the works were not entirely complete and not all the signs had been updated/installed... particularly where the B3275 crosses, they appear to be 20+ years old... also, the signposted route sends you right back the way you came, if you were travelling north, which stuffs up any attempt to navigate without dragging out the compass/satnav!).

It now forms a connecting route to unclassified routes to Belowda (via an impressive bridge over the bypass) and St Dennis, as far as we could tell. There are what are presumably cycle lanes down each side of the roadway (different colour tarmac and dashed white lines, but no symbols or signs) but it is open to motor traffic and moderately busy, certainly enough for a couple of turning manoeuvres to hold us up for a minute or two.

There are also some ENORMOUS height warning signs either side of the bridge, twenty yards or so away from it, on both sides of the road, with permanently lit flashing orange lights. Presumably it is thought there will still be some HGV traffic, and putting in very obvious warnings would be more effective than digging out the road by another couple of feet and all the associated drainage issues. (The road is still NSL but I doubt a trucker would have trouble pulling up from 70 in the wet, let alone 40, given the distance they are visible from).

PS, just who was responsible for the planning and draughtsmanship, re - many of the reasonably major junctions and sliproads? We joined the road at Indian Queens (from the B3274 initially) and... oh... my... God. You're basically spat out onto a 3-lane 70mph motorway, with no hard shoulder and an acceleration lane of two or three car lengths (or one lorry-length), added to which it's at the lower end of an 8% or so gradient, which seemed to halve the car's acceleration (even at full throttle and very high revs) and take a sizable bite out of the top speed (65mph in third, anyone, for a 1600cc?). Luck was with us because traffic was light and I had my wits about me. The exit's just as bad (same deceleration lane length and curve radius) Someone needs slain for that, fingers crossed no accidents will result. Problem is that, though it may be one of the worse examples, it's far from on it's own. Might be more understandable if t'were a farm access, but this is a relatively major junction, and there's no hint given that a FAR easier entry/exit point for all directions exists with the A39 interchange a half mile further north.

Goss Moor (excessive unsourced POV piece moved here for inspection)
In Cornwall the A30 previously crossed Goss Moor along a single carriageway section of the road between Victoria and Indian Queens. This was a major bottleneck in the county's transport system until 2007. An iron railway bridge is also situated in the middle of this section in which the Par–Newquay branch line crosses. This was built a long time before the road was dualled at both ends, and so can only fit a single carriage way beneath it. Due to its height (14 ft 3 in), many lorries in previous years had crashed into it, blocking the whole road completely.

There were plans to restore the rest of the St Austell – Indian Queens freight line (currently only going as far up as St Dennis), and direct rail traffic that way, but this plan was dropped. The road had been subject to a long-running campaign for expansion. As Goss Moor is a national nature reserve, it is one of the most highly protected wildlife sites in the UK, and plans for expansion were strongly opposed. In late 2004 a decision was finally reached, and a new dual carriageway now runs around the moor with the existing road converted to a cycle lane. The first 4 mi section of the new dual carriageway between Highgate Hill and the new Victoria Interchange opened at midnight on 9/10 May 2007. The former bottleneck of the iron bridge having now been eliminated means that problems with HGV lorries being stuck under the bridge should be a thing of the past. The remaining 3 mi stretch of new dual carriageway between Victoria Interchange and Innis Downs roundabout opened on 25 June 2007.

The new dual carriageway means that average travel times along this section of the route have reduced significantly. Several petrol stations along the old route have now closed down, and the former route across Goss Moor is now silent once more. The remains of a Stone Age settlement were discovered along the new route during construction.
