The Fens Waterways Link is a project to improve recreational boating opportunities in the counties of Cambridgeshire and Lincolnshire, England. By a combination of improvements to existing waterways and the construction of new links a circular route between Lincoln, Peterborough, Ely and Boston is planned. The project is being organised by the Environment Agency and financed from the Regional Development Agency and the European Union.
A separate, complementary waterway is the Bedford and Milton Keynes Waterway, opening up a route for broader beam boats between The Fens and the rest of Britain's canal network.
The Environment Agency has obtained a "significant proportion" of the £8m required for phase one. Starting from the north, the first development was the provision of a new tidal lock from the Haven in Boston to the South Forty-Foot Drain at the Black Sluice, opened to traffic on 20 March 2009. Funding for phase two of the project, which will involve widening of the South Forty-Foot Drain from Donington to a new road crossing under the A151 road, a new lock and a junction with the River Glen, a tributary of the River Welland, at Guthram Gowt has been secured from the East Midlands Development Agency.
To connect the Glen to the Welland requires a new tidal lock at the Surfleet Sluices and reconstruction of the tidal Fulney Lock in the River Welland, leading to Spalding.
