A38 is a major trunk road in the United Kingdom linking the southwest county of Cornwall and the city of Birmingham in the West Midlands. It serves as a principal arterial route connecting ports, commercial centres, and regional hubs such as Plymouth, Exeter, Bristol, Wolverhampton and Derby while linking to motorways including the M5 motorway and M6 motorway. The route traverses varied landscapes from coastal Cornwall and the Devon moorlands to the urban centres of Gloucestershire and Staffordshire.

Route description

The road begins near Bodmin and proceeds southwest into Plymouth, skirting the English Channel coastline and passing near the naval base at Devonport. North-eastward it crosses the River Tamar into Devon, serving Tavistock and joining dual carriageway sections approaching Exeter where it intersects the M5 motorway and provides links to Exeter Airport and Devon County Council administrative areas. Continuing northeast, the A38 runs through Taunton hinterlands before traversing Somerset landscapes near Bridgwater and meeting arterial routes to Bristol and the Severn Estuary.

The A38 then follows the line of the historic Portway and contemporary dual carriageways across Gloucestershire and into Worcestershire, passing through or near Worcester, Droitwich Spa and the market town of Evesham with connections toward Cheltenham and Tewkesbury. Further north it serves the industrial towns of Wolverhampton and Walsall, running adjacent to the West Midlands Metro catchment and providing access to the Birmingham conurbation. The northeastern terminus lies in Birmingham, offering junctions with radial roads toward Derby and Nottingham.

History

Sections of the route follow ancient trackways and coaching roads documented in county records of Devon and Cornwall and were upgraded in the 18th and 19th centuries concurrent with turnpike trusts such as the Exeter Turnpike Trust. The industrial revolution increased traffic to the docks at Plymouth and the coal and steel areas of the Midlands, prompting 20th-century improvements coordinated by ministries including the Ministry of Transport (United Kingdom). Post-war road-building programmes led to bypasses around market towns, influenced by plans from the Road Research Laboratory and national schemes embodied in White Papers of the UK Government.

Major 20th-century works included construction of dual carriageways in Devon and Somerset, realignments to create the long dualled sections known locally as the Devon Expressway, and creation of urban bypasses near Worcester and Birmingham coordinated with county councils such as Devon County Council and Worcestershire County Council. Key historical events shaping the route include delivery of motorway connections with the M5 motorway in the 1970s and integration with freight networks serving Port of Plymouth and Midlands distribution centres such as those near Coventry.

Junctions and exits

Notable interchanges include the junction with the M5 motorway at the Exeter spur, grade-separated junctions near Taunton providing access toward Bridgwater, and the A38(M) spur that historically linked to sections of the M6 motorway network. Urban junctions in the West Midlands provide connections to radial roads toward Wolverhampton, Walsall, and central Birmingham. The route crosses major river crossings including the River Tamar near the Tamar Bridge and the River Avon in Bristol-adjacent corridors.

Key roundabouts and interchanges are managed in partnership with local authorities such as Plymouth City Council and national agencies including National Highways; these junctions feature traffic signal control, grade separation, and in some cases collector-distributor lanes to manage flows to industrial estates and retail parks near Worcester and Derby. Freight terminals and park-and-ride interchanges provide modal transfer points for the Freight Transport Association and logistics operators serving Birmingham and the southwest ports.

Traffic and usage

The A38 carries mixed long-distance and local traffic, including heavy goods vehicles traveling between the southwest ports at Plymouth and distribution hubs in the Midlands and East Midlands. Peak volumes occur on commuter corridors into Birmingham and on sections serving holiday traffic toward Cornwall and Devon; seasonal peaks align with ferry services at Plymouth and leisure destinations in Torbay and the Cornish coast. Traffic monitoring and studies by bodies such as the Department for Transport (United Kingdom) and regional transport authorities indicate congestion hotspots at urban approaches in Bristol-adjacent areas and complex junctions in the West Midlands.

Safety audits conducted by county authorities including Devon County Council, Somerset County Council, and Warwickshire County Council have led to targeted interventions: hard-shoulder extensions, improved signage conforming to standards from the Highways Agency era, and speed management schemes near schools and market towns like Tavistock and Droitwich Spa. Public transport services use sections of the A38 for interurban coach routes linking stations such as Plymouth railway station, Exeter St Davids, and Birmingham New Street.

Future developments and proposals

Planned schemes proposed by National Highways and local authorities include targeted capacity upgrades, junction reconfigurations near Worcester and strategic safety improvements on rural sections through Devon. Proposals have been discussed in frameworks from regional bodies like West Midlands Combined Authority and county transport plans from Cornwall Council to improve resilience against coastal erosion near Plymouth and to enhance multimodal freight linkages to inland ports and rail freight terminals at Birmingham Rail Freight Terminal.

Longer-term proposals examined in national road investment strategies and local transport plans consider electrification of roadside infrastructure to support electric HGV charging developed in consultation with industry groups such as the Freight Transport Association and vehicle manufacturers including Leyland Trucks. Community consultations and planning applications lodged with district councils across Somerset, Gloucestershire, and Staffordshire will determine the phasing and environmental mitigations for upgrades affecting heritage sites and conservation areas near Exeter and Worcester.
