There is a runway/taxiway segment to the roundabout that links the A62 to the M62 / M621 - this used to be part of an actual roundabout but is now just grass due to changes in the road layout.
Routing works perfectly at present and I presume it’s a runway/taxiway to retain the roundabout status but I just wanted to double check this in case the segment can be removed.
