Prior to the construction of the interchange with CR 97 (Nicolls Road), exit 62 was for Morris Avenue and Waverly Avenue eastbound, and Morris Avenue westbound. Between exits 63 and 64, the eastbound service road was intended to weave around a recharge basin and replace a local residential street. Residents would have lived on both sides of the service road, similar to the segment between exits 59 and 60. Exit 68 was originally planned to be built as a cloverleaf interchange without collective-distributor roads. Additionally in the 1970s, Suffolk County Department of Public Works proposed an extension of East Main Street in Yaphank (CR 102) that would have terminated at the west end of this interchange.
