The question of inadequate access might be solved one of three ways. One, widen the entrance, increasing the throughput but not adding extra ticket facilities. Two, extra entrances on the city side, perhaps by pushing the ticket facilities out into the sides of the building or sending people around the sides. Thirdly, by building new facilities on the cattle market side. I would go for the third, since it would also improve access from Hills Road, take in anyone coming from the south and east, thus reducing throughput at the main entrance and might add extra car parking. Two ticket offices would need extra staff, but the costs might be worth it.
