This article is about the current junction 6 of the M74. For the original junction 6, see Maryville Interchange.
Hamilton Interchange is the very large junction 6 (originally junction 4) on the M74 for Motherwell and Hamilton. It is large due to being the junction for the unbuilt Glasgow orbital motorway.
It was substantially completed in time for the December 1966 opening of the southward M74, and fully completed in 1968 with the opening of the northward M74. It was originally junction 4, but became junction 6 when the numbering system was reversed in 1986 (see M74 and A74(M) History).
If rotated anticlockwise through an angle of about 50 degrees it would be extremely similar in shape, size and orientation to Eccles Interchange, though Hamilton also includes grade-separated routes for pedestrians and cyclists going generally parallel to the A723.
