About the Fosse Way
The Fosse Way is a Roman road about 372 km long in the Itiner-e atlas of ancient roads. It is mapped as 34 separate segments within the United Kingdom. 9 Roman places lie along it, from Isca Dumnoniorum to Ratae.
None of the Fosse Way is classed as certain: almost all of it is conjectured, so the line on the map is a best estimate of the course rather than a surveyed route.

| How certain | Length (km) | Share |
|---|---|---|
| Certain | 0 | 0% |
| Conjectured | 369 | 99% |
| Hypothetical | 3.6 | 1% |
Certain: well documented, mapped to within about 50 to 200 m. Conjectured: known road, course less precisely documented. Hypothetical: route not pinned down, or existence uncertain.

Modern roads that follow it
Many of today's roads were built on top of Roman ones. These numbered roads in Great Britain run along or very close to the line of Fosse Way. About 75% of the route in Great Britain lies on a numbered road of some kind.
- A429: 54 km (14% of the route)
- A46: 47 km (13% of the route)
- B4455: 45 km (12% of the route)
- A37: 19 km (5% of the route)
- A367: 15 km (4% of the route)
- B4114: 9 km (3% of the route)
- A303: 9 km (2% of the route)
How we worked this out: we checked every 50 metres along the Roman line for a numbered road within 200 metres heading the same way (within 20 degrees). A road is listed only if it follows the route for at least 8 km in total and 3 km in one stretch. These matches are approximate, because the Roman line is often a best guess.
