Barges from middle North America were able to reach the Atlantic Ocean from the Great Lakes when the Welland canal opened in 1824 and the later Erie Canal opened in 1825. By 1848, with the opening of the Illinois and Michigan Canal at Chicago, direct access to the Mississippi River was possible from the lakes. With these two canals an all-inland water route was provided between New York City and New Orleans. The
Hatherton Canal re-aligned canal. In 2006, the engineers Arup produced a feasibility study for a replacement route for the destroyed section which would link to Grove Basin on the Cannock Extension Canal. Environmental concerns led to a second feasibility study being produced by Atkins in 2009, for a route which connected to the derelict Lord Hayes Branch on the Wyrley and Essington Canal. A short section near the junction with the Staffordshire and Worcestershire Canal is navigable, and the cost of restoring the rest and building the new route to the Wyrley and Essington was estimated at £44.1 million in 2009.
