The Wiki article for the junction shows how the original layout was meant to be completed if you're interested.
How would you like your grade separations, Sir?
Big and complex.

From the SABRE Wiki: Holbeck Interchange :

Holbeck Interchange is junction 3 on the M621 serving the central area of Leeds. It was formerly junction 47 of the M1.

The junction was designed to connect three of the motorways entering Leeds - M621 from the southwest, which opened in 1975, M1 from the southeast, which opened in 1972 and the never built Leeds North East Urban Motorway. For a period of around 20
