Margary's Roman road numbering system, devised in the 1950s, gave the route from Londinium to Isca Dumnoniorum the number 4; the Port Way section is 4b. He recorded the distance of this section as .

From Calleva Atrebatum, the road continued the south-westerly course of
The Devil's Highway (
Margary route 4a) from Londinium.
Both
Ivan Margary and
Thomas Codrington believed the road left the town on its western side; Margary favoured the theory that it connected with the town's Lower West Gate,
although it possibly connected with the main West Gate.
Sir Richard Colt Hoare suggested that the road branched off Margary route 42 – the road from Calleva Atrebatum to

Hannington.
From Cottington Hill, the road takes on the heading of
Quarley Hill, near the present Hampshire–Wiltshire border, passes through
St Mary Bourne and crosses the

Beyond St Mary Bourne, near

Hoare believed that this was the settlement of
Vindomis,
and the Ordnance Survey's 25 inch to the mile map of 1895 marks it as "ROMAN STATION / Supposed to be VINDOMIS".
Charles Roach Smith wrote that the distance of Vindomis from Calleva Atrebatum given in the

Despite this,
Francis J. Haverfield wrote in 1915 that "there was no town or village at the crossing; so far as we know, there was not even a house at all".

Quarley Hill provided a line-of-sight with Sorbiodunum,
and from here the road took a south-west heading through the
Bourne Valley into present-day Wiltshire, crossing the river between
Winterbourne Gunner and
Gomeldon. At Sorbiodunum, the road entered the town on its east side,
where it was met by Margary route 45a, the road from Venta Belgarum.
Beyond Sorbiodunum, the road continued south-west to
Vindocladia (

Margary gave Portway the number 4b, and wrote that it was long.
Both Calleva Atrebatum and Sorbiodunum are listed in ''Iter XV'' of the Antonine Itinerary, although the distance given between the two towns – 55
Roman miles – is via Vindomis and Venta Belgarum rather than a straight route along Port Way.
Construction
In 1879, some of the road near St Mary Bourne was removed to provide better access for farm vehicles. The
metalled road surface was found between below ground level, and the road was approximately wide.
Further west, close to the
Amesbury branch railway in the parish of
Newton Tony, a section of the road in excellent preservation was carefully examined; Margary noted that both here and at Bradley Wood, the
''agger'' was wide.
The road here was bottomed with chalk, then layered with of flint, upon which a layer of local gravel was laid.
The road had been
cambered to give a thickness of at the centre.
There were V-shaped ditches on each side of the road, each deep and wide.
These were situated roughly from the south kerb and from the north kerb, making a total width for the road zone of to the ditch centres.

In 1889,
Thomas William Shore described how the "great military road" could be traced to the gate in the wall at Calleva Atrebatum, although some of the Roman roads around the town had been "obliterated".
In 1903, Codrington was unable to definitively trace the route between Calleva Atrebatum and Cottington Hill,
although in the 1950s Margary stated that the ''agger'' was visible on the

Pamber Green, and traces of the road could be made out near
Stoney Heath.
Like MacLauchlan and Codrington, Margary reported that tracing the route from this area was difficult, with little to be seen until the area of Hannington.
Here, the route of the road is now used by Meadham Lane, and a straight section of woodland known as Caesar's Belt is bordered on its north side by the road.

Referring to the Ordnance Survey's dead-straight projection of the road's course, Margary wrote that "near
Quarley and
Grateley it seems probable that the distinct ridge along the south side of the wide green lane marks it rather than the Ordnance Survey’s idealized straight line in the fields where there is no sign of it."
