I was asked about transportation to and from Tzur Hadassah. Thought I’d share the options – though they are not as many as would be helpful:
Bet Shemesh: Superbus 182.
Beitar: Illit buses; there are multiple lines that go to Jerusalem, Bet Shemesh and Bnei Brak frequently.
Tremping: People do tremp (hitchhike) from the front gates. I’ve also seen (and picked up) people hitchhiking from the trempiada at Gilo junction.
