A public meeting took place at the Sun Inn in Bradford on 2 July 1766 to promote the building of such a canal. John Longbotham was engaged to survey a route. Two groups were set up to promote the scheme, one in Liverpool and one in Bradford. The Liverpool committee was unhappy with the route originally proposed, following the Ribble valley through Preston, considering that it ran too far to the north, missing key towns and the Wigan coalfield. A counter-proposal was produced by John Eyes and Richard Melling, improved by P.P. Burdett, which was rejected by the Bradford committee as too expensive, mainly because of the valley crossing at Burnley. James Brindley was called in to arbitrate, and ruled in favour of Longbotham's more northerly route, though with a branch towards Wigan, a decision which caused some of the Lancashire backers to withdraw their support, and which was subsequently amended over the course of development. In 1768 Brindley gave a detailed estimate of a distance just less than built at a cost of £259,777 (equivalent to about £32.67 million as of 2014).
