The Boyne Navigation Company began work on on the lower section of the navigation from the sea lock at Oldbridge to Slane in 1748 and was completed in the 1760s.

With the decline in commercial trade on the canal system, even the final river section became little used, with most pleasure craft venturing only as far as Tarleton Lock, and it was not until 2002, with the opening of the Ribble Link that this section of the navigation began to see any appreciable traffic.

The Act of 1767 had specified points on the river at which tolls could be collected, but had made no mention of tolls for use of Bow Creek, Bow Back Rivers, or the section of the navigation between Bow tidal gates and Old Ford, and these had remained toll-free.
