Along with Haverford College, Bryn Mawr forms the Bi-College Community. Students in the "Bi-Co" enjoy unlimited cross-registration privileges and may choose to major at the other institution. The two institutions join with Swarthmore College to form the Tri-College Consortium, opening the Swarthmore course catalog to interested Bryn Mawr students as well. Free shuttles are provided between the three campuses. There is the Blue Bus between Bryn Mawr and Haverford College, and a van, known to the students as the "Swat Van", that travels among the three colleges.
