The Icknield Way - Thetford to Worsted Lodge

Margary Number: 333

Distance: 30 miles (Thetford - Worsted Lodge)

Believed to be an Iron Age trackway predating the Roman period but adopted and improved by the Romans where they deemed necessary. That's the theory but is it really that old? Doubts have been cast on its authenticity. Much of its route is down to W.G. Clarke (EDP Oct 1923).

Certainly in Suffolk much of the Icknield Way comprises long straight alignments.This would tend to support that it was a Roman road whether an upgrade or replacement. Generally is seems these days to be accepted as Roman.

Note the mapping for this road is reproduced here at half the scale normally adopted on our Suffolk web pages. The actual route depicted in based on OS Mapping with gaps filled in by interpolation.

Icknield Way - Nuns Bridges, Thetford

We start in Thetford at Nuns Bridges. Here, in close proximity, the Rivers Thet and Little Ouse are crossed at a truly delightful spot. The bridges are relatively modern and presumably replaced the ford of Thetford..

From Nuns Bridges to Thetford Heath then the course is uncertain so I have straight-lined it. From there onwards its course is shown on modern mapping. This first stretch goes by various names, Barnham Slip, Angles Way and St Edmund Way as well of course as Icknield Way.

Icknield Way - Icklingham

The Roman settlement of Icklingham was just west of the Icknield Way where it crosses the Roman road from Ixworth. Icknield Way crosses from right to left in this view.

Icklingham was probably Camborico of Antonine Itinerary V. The mileages are a couple of miles adrift (36.5 from Caistor & 27.5 from Cambridge) but it is the closest match available.

The route of the Icknield Way around the dry edge of the Fens makes perfect sense in this widefield view of the area.

The road passels through the King's Forest to Icklingham and then crosses the River Lark, The Roman bridge appears to have been downstream (east) of the modern bridge. It then heads from Lackford to Cavenham.

Its main roads all the way now. The straightness gives us the only real clue we are on Roman alignments.

Classical Roman road surveying - a series of straights from high point to high point. Absolutely certain this is Roman.

The route keeps inland of the Fens and the connection to Cambridge had to wait till Worsted Lodge to turn right.

Our road continues its course to where it crosses the Wixoe to Cambridge Roman Road (Worsted Street) at Worsted Lodge. Road upgrades have all but obliterated any trace of the original Icknield Way.

Lidar Image - Cambridge Link

For traffic heading down the Icknield Way to Cambridge then there appears to have been a short-cut cutting off the corner at Worsted Lodge. There is clearly an old road there and it would make a lot of sense if it were Roman.

Oblique Lidar Image - Worsted Lodge to Chestertford

Pretty simple alignment to the Roman fort and later town at Great Chesterford.

Inset: Old road now bypassed heading down to Bourn Bridge. Does that line of trees preserve the original Roman ditch line?

Lidar Image - Great Chesterford Site Plan

The Roman upgrade to the Icknield Way probably ended at Great Chesterford. The pre-Roman(?) trackway most likely went via Ickleton - quite a clue that name.

The early fort and later town extents are from Maria Medlycott, EAA Report 137, 2011.
