Understanding the roads in Salisbury is essential for anyone who lives in, works in, or visits this historic Wiltshire city. Salisbury’s road network is shaped by its medieval origins, modern traffic demands, and its role as a regional connector between the south coast, the West Country, and central southern England. While the city itself is compact, a small number of major roads handle the vast majority of vehicle movement, making them critical to daily travel and long-distance journeys alike.
This detailed guide explains the most important roads in Salisbury, how they connect, why they matter, and how to use them efficiently. Whether you are commuting, navigating the city centre, or passing through toward destinations such as Stonehenge or the Dorset coast, knowing how Salisbury’s key routes function can save time and reduce stress.
Understanding Salisbury’s Road Network
The overall structure of the roads in Salisbury is built around a ring-road system designed to protect the historic city centre while keeping traffic flowing. Rather than allowing large volumes of vehicles to cut through narrow medieval streets, Salisbury relies on the A36 ring road to move traffic around the city, with several major A-roads feeding into it from all directions.
This design means that congestion in Salisbury tends to concentrate at major junctions and roundabouts rather than along long urban stretches. When one key node slows down, the effects can be felt across the wider network. For this reason, understanding the main routes is more important than memorising every individual street.
The A36 Ring Road: The Backbone of Roads in Salisbury
The A36 ring road, often referred to locally by section names such as Churchill Way, is the single most important road in Salisbury. It functions as both a bypass for through traffic and the main distributor for vehicles accessing different parts of the city. National Highways identifies the A36 as the primary route through Salisbury, carrying tens of thousands of vehicles each day.
This road forms a near-complete loop around the city centre, connecting traffic from the A30, A338, and A345. Because of its strategic role, the A36 experiences heavy usage during peak hours and is particularly sensitive to incidents, roadworks, or signal failures. Traffic data published by National Highways shows that some sections of the A36 carry more than 30,000 vehicles per day, highlighting its importance not just locally but regionally as well.
In practical terms, the A36 is the route drivers should rely on when travelling around Salisbury rather than through it. Staying on the ring road until the correct exit is reached is usually the fastest and least disruptive option, especially during busy periods.
The A30: Salisbury’s Northeastern Approach
The A30 is one of the most significant entry routes into Salisbury, particularly from the northeast. As it approaches the city, it becomes closely associated with London Road, a key corridor for commuters, local residents, and visitors entering Salisbury from surrounding towns and villages.
This road feeds directly into the ring-road system and plays an important role in distributing traffic toward residential areas and city-centre access points. Because it serves both local and regional traffic, the A30 can experience congestion during weekday mornings and late afternoons. When incidents occur on the A36, the A30 often becomes a pressure point as vehicles queue to join the ring road.
For drivers approaching Salisbury from the northeast, the A30 is often the first indication of how busy the city is likely to be. Smooth flow here usually means the wider network is functioning well.
The A338: A Major Corridor Through the Avon Valley
The A338 is another essential route within the roads in Salisbury, connecting the city to areas to the south and beyond. Running through the Avon Valley, this road links Salisbury with Dorset and forms part of a longer north–south corridor toward Oxfordshire.
As the A338 reaches Salisbury, it interfaces with the ring road at key junctions that handle high traffic volumes. These junctions are known to be among the most sensitive parts of the network, particularly during peak commuting hours and busy weekends. Wiltshire Council has undertaken detailed traffic modelling around these areas, recognising the strategic importance of the A338 and its influence on congestion patterns across the city.
For many drivers, the A338 is the main route used to access Salisbury from the south. Its performance has a direct impact on travel times not only for Salisbury residents but also for those passing through the city as part of longer journeys.
The A345: Northern Gateway to Salisbury Plain
The A345 is the principal northern route connecting Salisbury with Amesbury, Marlborough, and the wider Salisbury Plain area. It is particularly well known to visitors because of its connection to routes leading toward Stonehenge and other historic sites.
This road joins the Salisbury ring road at a major roundabout, making it a crucial entry and exit point for traffic moving between the city and northern destinations. During peak tourist seasons, especially in summer, the A345 can experience significant increases in traffic volume, which can affect flow on the ring road itself.
For local drivers, the A345 serves as an everyday link between Salisbury and surrounding communities. For visitors, it often forms part of a longer journey that includes sightseeing, which can influence traffic patterns at different times of the day.
Key Junctions That Control Traffic Flow
In Salisbury, traffic conditions are often dictated more by junctions than by the roads themselves. Several major roundabouts along the A36 ring road act as control points for the entire network. These include College Roundabout, St Mark’s Roundabout, Castle Roundabout, and St Paul’s Roundabout.
National Highways has identified these locations as priorities for upgrades, including resurfacing and the installation of intelligent traffic signal systems. These improvements aim to make traffic flow more responsive to real-time conditions, but they also underline how critical these junctions are to the city’s mobility.
When congestion builds at one of these roundabouts, delays can quickly spread to feeder roads such as the A30, A338, and A345. Understanding where these pinch points are helps drivers anticipate delays and choose alternative timings when possible.
Parking Strategy and Park & Ride Options
Driving directly into Salisbury city centre is often unnecessary and can be inefficient, particularly at busy times. The historic core was not designed for modern traffic volumes, and parking availability is limited. As a result, Wiltshire Council promotes the use of Park & Ride facilities located on the main approach roads.
These sites collectively provide more than 2,000 parking spaces and are served by regular bus services into the city centre. They are strategically positioned near the A36, A30, A338, and A345, allowing drivers to leave their vehicles before reaching the most congested areas. For visitors, this approach often results in faster overall journey times and a more relaxed arrival experience.
Practical Driving Tips for Roads in Salisbury
Drivers using the roads in Salisbury can benefit from timing and route awareness. Peak congestion typically occurs during weekday mornings and late afternoons, as well as on Saturdays around midday. Shifting travel times by even twenty minutes can significantly improve journey reliability.
It is also important to stay informed about planned roadworks. National Highways has scheduled multi-year improvement works along the A36 Salisbury corridor beginning in early 2026, including temporary lane closures and junction restrictions. These works are designed to improve long-term reliability but may cause short-term disruption.
Using the ring road as intended, avoiding unnecessary trips into the city centre, and checking live traffic updates are simple but effective strategies for navigating Salisbury efficiently.
