A487 Caernarfon to Bontnewydd Bypass 31 October 2017
Construction of a new bypass to carry the A487 around Caernarfon and the adjacent villages of Llanwnda, Dinas and Bontnewydd. The new road will run from the Plas Menai Roundabout north of Caernarfon to the Goat Roundabout with the A499 south of Llanwnda, with two intermediate junctions in the form of flat roundabouts to connect with the A4086 Llanberis Road and the A487 north of Bontnewydd.
A55 Third Menai Crossing 31 October 2017
Provision of extra road capacity for the A55 across the Menai Strait between the Welsh mainland and Anglesey. At present, the A55 forms a continuous and mostly grade-separated expressway from Chester to Holyhead, except at the Menai Strait where it reduces to a single two-lane road to cross the Britannia Bridge. The scheme aims to provide two lanes in each direction at this crossing.
A55, A494 and A548 Deeside Corridor 25 October 2017
A new route, consisting partly of an entirely new dual two-lane road and partly an upgrade to the existing A548, between the A55 at junction 33 (the A5119 at Northop) and the A494/A550 junction complex at Shotwick, intended to relieve the existing A494 and A55 between those points. The new dual carriageway will run from the A55 at junction 33 to Connah's Quay Power Station. From that point, the A548 will be upgraded to form a free-flowing expressway with grade-separated junctions, crossing the Flintshire Bridge, with a new direct connection to the A494 at Shotwick leading to the M56.
A4232 Eastern Bay Link: Queensgate to Ocean Way 28 May 2017
An extension of the existing A4232 Cardiff Peripheral Distributor Road from its existing terminus at the Queen's Gate roundabout east to the Ocean Way roundabout in Cardiff. The scheme is intended to aid economic regeneration and to relieve pressure on Central Link, East Tyndall Street and Ocean Way. The new road will need to maintain private road and railway links and will include construction of a 700m viaduct and a 300m embankment.
M4 J28 Improvement 10 April 2017
Modifications to the existing roundabout at M4 junction 28, which handles interchange movements between the M4 sliproads, the A48 and the A467. The roundabout will be modified to a teardrop shape, with closure of the part between the westernmost entrance and exit, and a new cut-through installed to enable traffic travelling eastbound on the A48 to pass through the middle of the junction. A new section of road will pass around the west side of the flyover carrying the eastbound A48 to replace the closed section of roundabout.
M4 Newport Relief Road 8 March 2017
Construction of a new dual three-lane motorway to the south of Newport, from junction 23 of the existing M4 to junction 29, in order to replace the existing motorway which suffers severe operational and congestion problems.
This solution has been chosen partly because widening the M4 and bringing it up to modern standards would be prohibitively difficult - in particular with regard to the Brynglas Tunnels and the twisting alignment.
A465 Dowlais Top to Hirwaun Dualling 24 November 2016
Upgrade of the existing single three-lane A465 Heads of the Valleys Road between Dowlais Top and Hirwaun to provide a grade-separated dual two-lane expressway.
This scheme will be the final upgrade of the complete route from Abergavenny to Neath and will complete the continuous dual carriageway route between the A40 and M4 that has been progressively constructed since the mid-1970s.
A465 Gilwern to Brynmawr Dualling 5 September 2016
Mostly online upgrade of the existing A465 between Gilwern and Brynmawr to dual two-lane standard with full grade separation. Most of this scheme lies within the Brecon Beacons National Park, and the road passes through the ecologically sensitive Clydach Gorge.
The main contractor, Costain, was appointed in June 2011.
This is section two of the Heads of the Valleys project, and is likely to be the fourth of the six sections to be completed.
A483 and A489 Newtown Bypass 17 June 2016
Construction of a new single carriageway road to bypass Newtown to the south, in order to reduce congestion in the centre of Newtown. The new road will follow the preferred Orange Option. Construction began in March 2016, with a given completion date of Winter 2017/18.
A bypass for Newtown was first planned 40 years ago.
A487 New Dyfi Bridge 20 December 2015
A new viaduct and bridge will be built to carry the A487 over the River Dyfi and surrounding floodplain north of Machynlleth, approximately 480 metres to the east of the existing bridge. The old Pont-ar-Ddyfi will remain open for local and pedestrian access only.
The main aims of this scheme are to improve journey reliability, and to protect the existing, Grade II*-listed bridge over the River Dyfi (Pont-ar-Ddyfi). The historic bridge is a cause of delays, both because of its narrowness, and also because it is frequently closed due to flooding, resulting in long diversions.
The Heads of the Valleys 24 October 2015
The A465 Heads of the Valleys Road is one of the most spectacular trunk roads in the UK, and building it required some of the most remarkable civil engineering. This is the story of how the road was built in the 1960s, and how it's being rebuilt today.
A470 Maes yr Helmau to Cross Foxes Improvement 19 November 2014
Realignment of a narrow and winding section of the A470 in the Snowdonia National Park, just east of Dolgellau. The new road will be 7.3 m wide single carriageway, with minimum 2.0 m verges.
The aims of the scheme are to improve safety and reduce journey times.
The Made Orders were published in the London Gazette on 2 February 2012, and work started on 15 March 2012. The contractor is Alun Griffiths.
A477 St Clears to Red Roses Improvement 19 November 2014
The aims of the scheme are to improve safety, provide better overtaking opportunities, and reduce journey times on a sub-standard section of the A477 in south-west Wales.
The improvement consists of a new offline single carriageway road, 8.7 km in length, running from the A477/A40 St Clears roundabout and then bypassing Llanddowror and Red Roses to the north before re-joining the existing A477 at Llanteg. Sections of 2+1 will be provided to improve opportunities for overtaking.
The preferred route was announced in October 2006 and then amended follow a review in 2008/09.
A40 Llanddewi Velfrey to Penblewin Improvement 26 May 2012
Reconstruction of a two-mile section of the A40 in West Wales to provide a high quality single two-lane road.
The aim of this scheme is to provide better overtaking opportunities on a narrow and winding section of the A40, and thus improve safety. The scheme will also include a bypass for the village of Llanddewi Velfrey.
A470 Cwmbach to Newbridge 10 December 2011
The aim of this scheme is to replace a winding section of the A470 north of Builth Wells with a new single carriageway road to improve safety and overtaking opportunities. The new road will also allow traffic to avoid the low bridge at Cwmbach and the traffic lights at Pont-ar-Ithon.
A487 Porthmadog Bypass 18 October 2011
M4 Variable Speed Limits Magor - Tredegar Park 17 June 2011
Upgrade of the central reservation to concrete step barrier, and the construction and implementation of a Variable Speed Limit scheme, between junction 23A (Magor) and Junction 28 (Tredegar Park). This will replace the current temporary 50mph speed limit on the M4 Newport Bypass.
