The semi is mapped as 2 Newlands https://www.openstreetmap.org/way/357596008 and 4 Wardville https://www.openstreetmap.org/way/285632622 and then numbers 6 to 14 show before Yokecliffe Drive (previously these were incorrectly showing as 4-12 but are now correct I believe)
Unfortunately inappropriate to refer to GSV as their license terms are incompatible
