Well I figured I could make a way to connect 6th Ave to SAS, and the is a good contestant to enable a Culver Express. Sea Beach is also crowded, and I figured I didn't want the to mirror the . Crowded Sea Beach then would have two connections, one to Broadway and one to 6th Ave.
EDIT: Forgot to include SAS has a connection to 6th Av, until Section 3 and 4 open up
