The B4037 is a short B-road near Daventry.
It starts on the A361 at the northern end of Badby, although for the first few years it started on the next road north. From here the road heads eastward, following the River Nene downstream to Newnham. After winding its way through the village and climbing a little higher up the valley side, the route continues to a terminus on the A45 near Dodford. The 1922 Road Lists claim that the road extended to Weedon Bec – but the road beyond this point has always been the A45.
