The River Usk rises on the northern slopes of the Black Mountain, Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course.
The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
The A41 is a trunk road between London and Birkenhead, England. Now in parts replaced by motorways, it passes through or near Watford, Kings Langley, Hemel Hempstead, Aylesbury, Bicester, Solihull, Birmingham, West Bromwich, Wolverhampton, Newport, Whitchurch, Chester and Ellesmere Port.
The A40 is a trunk road which runs between London and Goodwick (Fishguard), Wales, and officially called The London to Fishguard Trunk Road (A40) in all legal documents and Acts. Much of its length within England has been superseded by motorways, such as the M40, and has lost its trunk road status, though it retains it west of Gloucester, including its length within Wales. It is approximately 260 miles (420 km) long. The eastern section from Denham, Buckinghamshire to Wheatley, Oxfordshire is better served by the M40 and its former function of linking London with Cheltenham and Gloucester has been taken by the M4, A419 and A417 via Swindon.
Newport is a city and county borough in Wales, situated on the River Usk close to its confluence with the Severn Estuary, 12 mi (19 km) northeast of Cardiff. With a population of 145,700 at the 2011 census, Newport is the third-largest authority with city status in Wales, and seventh most populous overall. Newport became a unitary authority in 1996 and forms part of the Cardiff-Newport metropolitan area. Newport was the site of the last large-scale armed insurrection in Great Britain, the Newport Rising of 1839. The population grew considerably during the 2021 census, rising to 159,587, the largest growth of a unitary authority in Wales.

Its route is similar to that of the London, Tilbury and Southend line via Rainham, Grays, Tilbury & Stanford-Le-Hope, and runs the entire length of the northern Thames Gateway area, terminating on the Thames Estuary at Shoeburyness. It is a trunk road between London and the Tilbury junction, a primary route between there and Sadlers Hall Farm near South Benfleet, and a non-primary route between there and Shoeburyness.
The A48 is a trunk road in Great Britain running from the A40 at Highnam, 3 miles (4.8 km) west of Gloucester, England, to the A40 at Carmarthen, Wales. Before the Severn Bridge opened on 8 September 1966, it was a major route between England and South Wales. For most of its route, it runs almost parallel to the M4 motorway. During times of high winds at the Severn Bridge, the A48 is used as part of the diversion route and is still marked as a Holiday Route.
The A49 is an A road in western England, which traverses the Welsh Marches region. It runs north from Ross-on-Wye in Herefordshire via Hereford, Leominster, Ludlow, Shrewsbury and Whitchurch, then continues through central Cheshire to Warrington and Wigan before terminating at its junction with the A6 road just south of Bamber Bridge, near the junction of the M6, M65 and M61 motorways.

The Milton Keynes grid road system is a network of predominantly national speed limit, fully landscaped routes that form the top layer of the street hierarchy for both private and public transport in Milton Keynes, Buckinghamshire. The system is unique in the United Kingdom for its innovative use of street hierarchy principles: the grid roads run in between districts rather than through them. This arrangement permits higher speed limits due to the absence of buildings close to the roads – although more recently some have been limited in part to 40 mph (64 km/h). The grid road system also serves an important purpose of discouraging through-traffic from travelling through neighborhoods and thus reduces traffic noise and pollution from pedestrian areas. Motor traffic is segregated from pedestrian and leisure cycling traffic, which uses the alternative Milton Keynes redway system. Almost all grid junctions are roundabouts, and the absence of traffic lights enables free and efficient movement of traffic.
The A4161 is a main road in Cardiff, Wales, United Kingdom. The main purpose of the road is to link the city centre with the M4 motorway in the west at junction 33, and in the east with the A48(M) motorway at St Mellons.
