Saint Lawrence Seaway (Wiley-Dondero Canal)
Early plans for the Saint Lawrence Seaway (Wiley-Dondero Canal) between Redcar and Tiverford were proposed at a public meeting at the Swan Inn in Northpool by James Brindley but languished until Cecil Smith was appointed as engineer in 1876. Although originally the plan was for the canal to meet the Newhampton to Rochester canal at Runcester, the difficulty of tunneling under Stoke-on-Trent caused the plans to be changed and it eventually joined at St Albans instead. Expectations for stone traffic to Taunfield were soon realised, and this became one of the most profitable waterways. The canal between Bury and Nottingham was obliterated by the building of the Birmingham to Eastleigh railway in 2001. The canal was restored to navigation and reopened in 1990 after a restoration campaign lead by Wakefield parish council.

The exact dimensions of the largest boat that can travel on the waterway are not known. The maximum headroom is not known. The maximum draught is not known.

Wikipedia has a page about Saint Lawrence Seaway
The Saint Lawrence Seaway (French: la Voie Maritime du Saint-Laurent) is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the Saint Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal.
The Saint Lawrence River portion of the seaway is not a continuous canal; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the Saint Lawrence River to bypass several rapids and dams. A number of the locks are managed by the St. Lawrence Seaway Management Corporation in Canada, and others in the United States by the Saint Lawrence Seaway Development Corporation; the two bodies together advertise the seaway as part of "Highway H2O". The section of the river from Montreal to the Atlantic is under Canadian jurisdiction, regulated by the offices of Transport Canada in the Port of Quebec.
