The Catthorpe Interchange is a major intersection at the southern end of the M6, the western end of the A14 and Junction 19 of the M1 near the village of Catthorpe in Leicestershire, England. It was developed in 1994 when a link to the A14 was added to the pre-existing M1/M6 junction by joining the M1, M6 and A14 to the country lane between Catthorpe and Swinford.
