Through-routing Transbay Buses

As currently planned all of AC Transit’s transbay buses are scheduled to terminate at San Francisco’s new Transbay Transit Center. Why? Is that the only possibility? This is causing a horrendous bus storage problem. Storing buses in downtown San Francisco is expensive. So why not “thru-route” some of the AC bus lines; that is, combine some of them with a corresponding Muni, SanTrans or Golden Gate line? This would both reduce the need for downtown storage and provide new transit connections for riders. The idea is not new. In fact it’s been talked about at MTC for over 40 years.
