Down to the work on the Eastern Transport Corridor, where the road-building team have painstakingly uncovered part of the old 1825 Stockton to Darlington trackbed.
About 5 feet below the surface of the bridleway is a line of dressed stone which probably carried the railway line at some point after 1825. Broken stones with drilled holes containing fragments of wood and metal represent the earliest phase of the railway, which was taken up and replaced by the dressed stone now in situ.
Archaeologists will be digging trenches on Tuesday and Wednesday to explore the remains further, and make better sense of what's been discovered.
This represents a pivotal moment not only in the history of the town, but also of the Industrial Revolution as a whole. Whilst much of the trackbed will have to be preserved and reburied, I hope that we can incorporate some of it into a display on the cyclepath along the Eastern Transport Corridor. Now it's over to the archaeologists to tell us what we have here.
