Admittedly, this one is a little bit meta. The M1 and M62 intersect about this point, with a large roundabout, cuttings and flyovers part of the design to keep traffic flowing. There is no way to stop around this area from either motorway, however Long Thorpe Lane threads through the various parts of this junction, which has a number of safe places to pull over.
If travelling on the M62, the lanes connecting J28 and J30 are rather favourable for a short diversion. Routes are available between J44 and J41 of the M1, however these may prove a little more convoluted. This area can however become gridlocked at rush hour if either of the two motorways back up, so may be best avoided at those times.
The cache is a micro container, on the larger size of this size bracket, a short walk from a couple of easy places to pull in. This cache is intentionally situated away from the various bridges of the junction, but the traffic can still be heard rumbling around in all directions.
