The Spread Eagle at Cottenham
The B670 is a short link road near Corby.
It starts on the A427 and heads north, skirting East Carlton Park. This first section of road is actually part of the original line of the A427; the B670 originally began a few hundred yards further on, at the point it now bends sharply left (with the ex-A427 continuing to the right).
The road now goes through Middleton, where there is a sharp right bend onto Main Street, before reaching the adjacent village of Cottingham, where there is a sharp right bend onto High Street. The road then reenters open country and heads northeast for over a mile to end on the A6003 at the northern end of the village street in Rockingham.
