The temporary locks were used as a means of getting the canal open to through traffic by 1800 (this river crossing and the tunnel at Blisworth being the only two gaps by that year).

It was replaced by the present Cosgrove aqueduct, built of cast iron, and opened on 22 January 1811.

By this method it kept until the following spring and summer, when it would be sold to local fishmongers, butchers and others in the days before refrigeration.

For a while the village was a very busy trading centre, with iron tracks at the canal wharf still evident, but as traffic moved to the railway (now the West Coast Main Line) and roads improved, life and business in the village slowed down again.

[5] Cosgrove Hall and its estate was built in the early 18th century on the site of an earlier house by the Furtho family.

[5] South-east of Cosgrove Hall and the church on the south bank of the canal is the site of a Roman Villa, bath house and temple discovered in 1957 and excavated in the 1950s and 60s.

The site is also home to rare insects such as the ground beetle and birds such as the skylark and barn owl.

[5] Cosgrove Leisure Park, a caravan site, attracts many visitors, caravanners and holiday-makers.

The park surrounds an area of flooded gravel pits beside the Tove and Great Ouse, south of the village.
