1Dorset Road Infrastructure Improvements. Dorset is a very expensive area to build in, but has less transport demands than other counties. So although the money buys less, it doesn’t need a motorway, it just needs a reasonable transport structure other decent single carriageways, and a strong dual carriageway backbone.Other counties need more lanes, and more roads, Dorset needs one trunk road, and good link roads to the towns alongside.Most of the roads already exist, they just need straightening and widening.The bare minimum is to tackle the congestionThe next target is to add safer roads with good over taking placesThe ultimate target is an renovation to our trunk road that carries people from one end of the county to the other, and bypasses the Poole and Bournemouth conurbation with seriously powerful link roads to the heart of this area.There is environmentally protected land, but there are alternatives – but these are more costly.Building costs are still rising in Dorset, if we don’t build now, the costs will double very soon.
2The very bare minimum plan for Dorset to achieve the goal of tackling the most congested spots. Total Cost: £555MPoole Link Road £150M (Ameysford roundabout to Mannings Heath roundabout)Grade separated dual carriagewayDumbbell junction A341Dumbbell junction B3073Wallisdown Bypass £120M (Alderney roundabout to A338 Richmond Hill Speed Camera)Dumbbell junction A3040Ringwood Junction A31 £20MWestbound carriageway widened to 3 lanes from Ringwood to Ashley HeathChristchurch Bypass £100M (BlackWater junction to Christchurch Bypass)Dual carriageway – no junctionsBlackWater Junction rebuilt as motorway style junctionWareham Link Road £100M (Baker Arms roundabout to Wareham Bypass North roundabout)Dual carriageway - at gradeRoundabout access for Holton HeathRoundabout (link single carriageway road) to Morden RoadPuddletown Bypass extension £50M (Bockhampton to Stinsford Roundabout)Dual carriageway – LILO junctions onlyWool Northern Bypass £15M (Woolbridge Manor to Burton Cross roundabout)Single Carriageway – no junctions
3The bare minimum with expandability, the goal being to improve safety on dangerous roads and link towns with the main road network. As well as providing the safest overtaking options.Defining ‘Fixed 3 lane sections’ as a 3 lane road where only one direction may use it, mininum ¾ mile. As A303 Illchester bypass.Additional Cost: £180MSwanage Link Road £80M (Corfe Castle to Swanage, alongside railway line)Single carriageway with 4 fixed 3 lane sections where possibleWeymouth A354 enhancement £20M (Stadium roundabout to relief road)Additional 3 lanes sections in each direction where possibleWool Bypass upgrade to Dual Carriageway £10MDual carriageway from Burton Cross roundabout to Tout Hill roundabout)Other Bypasses (single carriageway)Broadmayne £20MLytchett A350 area £20MOther Fixed 3 lane sectionsA352, 4 sections £15MA350, Roundhouse roundabout to A35, 4 sections £15M
4The long term plan for Dorset, a single high capacity fast Trunk Road (A31) from Dorchester to Ringwood. (Renumbering Puddletown Bypass). A35 follows Wallisdown bypass, Upton Bypass, Wareham Bypass, current A352, joins A31 at existing Wareham junction on Dorchester Bypass.Additional Cost: £410MBere Regis to Winterbourne Zelston £50MWiden existing road, built new carriageway alongsideGrade separated junction at Bere Regis, link to Winterbourne Kingston roadWinterbourne Zelston to A350 £100MGrade Separated (small) junction with B3075Full Grade Separated Junction with A350A350 to St Huberts Church £40MDumbbell junction with B3074 (and existing A31 downgraded to B3074)St Huberts Church to Lake Gates roundabout £20MLILO for side road accessDumbbell junction for Lake GatesLake Gates to Canford Bottom roundabout £70MNew course bypassing Merley roundabout, existing road become slip roadsFull Grade Separation at Canford Bottom roundaboutCanford Bottom Roundabout to Ameysford roundabout £30MFull Grade separation at Ameysford for Poole Link RoadSt Leonards 3 lane Dual Carriageway bypass £100M
5Upgrade to A350 from A31 to A35, serves West side of Poole and Wareham. Cost £30M
6Other nearby upgrades in other Counties Upgrade of A338 from Ringwood to M4 to full grade separated dual carriageway, including:Eastern Bypass for SalisburyWide Southern A303 Bypass around Stone Henge (interplex with A338)Dual carriageway link to A36 (Southampton)Cost £1.5BNBenefits:Major relief to A31 New Forest, and entire A34.A338 continues past M4 as existing A419 continuous dual carriageway to M5 (bar 1 miles)Completion of A303 Grade Separated Dual Carriageway to M5 using A358Cost £500MBenefits: Major link road from Cornwall / Devon to London completed.Southern and Eastern Bypass for Lymington (A337 / A35 interplex to dual carriageway)Cost £80MBenefits: Major stress relief to LymingtonMajor enhancement to free flowing traffic in New ForestA31 (New Forest) uphill 3 lane sections, GSJ at Rufus Stone, and additional junctions to serve New Forest.Cost £50MBenefits: Help New Forest benefit from A31
