The completion of the Bure navigation canal (Aylsham Navigation) in 1773 brought further wealth to the prosperous town.

"The Bure, which washes the foot of the town, was formerly only navigable from Yarmouth to Coltishall, (11 miles below Aylsham bridge by the water, and 7 by land;) but in 1773, an act was obtained for extending the navigation to Aylsham, for boats of 14 tons burthen, drawing two feet five inches water, which was completed after many difficulties and interruptions, in Oct., 1779, at a cost of upwards of £6000, including the cost of the basin and wharfs near the bridge, where much business is done in coal, corn, timber, &c."
