I had suggested in order to close 東京街總站 and Nan Cheong MTR 總站, and use 寶輪街 KMB depot or 深旺道 car park as bus terminus last year, and also move KMB 12 and all buses to there.
I think they cannot use the existing KMB 12 as terminus because there is a A21 busstop with a lot of constructions such as rebuilding the foot bridge.
Seems no one can foresee the feasibility, it will thus make a lot of traffic congestion.
