Evidence suggests that Navenby was a significant staging point along Ermine Street.

This is most obvious east of Ermine Street, though there are traces to the west.

A bypass now means that most traffic can avoid Ermine Street, and it is comprehensively traffic-calmed.

To the east lies the course of Ermine Street, now the Viking Way.

The town has a well-preserved medieval bridge that used to serve as the main route of Ermine Street over the river.

Ermine Street would have first crossed the river here via a ford, believed to be some way to the west of the present bridge.

The A15 section along Ermine Street was planned to be opened at the same time, but it had to wait twelve years.

Ermine Street later became known as the Old North Road.

Later, Ermine Street would be built directly on top of it.
