This is why I think we should focus on the local level just as much as the regional level, making sure each regional line connects to an efficient and extensive local mass transit network.
Also, the Big K shopping center, at the mouth of Parley's Canyon could be an inter-modal hub with high density housing, eventually connecting a Park City line to Bus Rapid transit on 3300 and 3500 South to Magna, then eventually to Toelle. The SugarHouse spur could connect to the Hub, and so could another transit mode, running down Foothill.
