NOTES: This was to have been a four-lane divided, bypass route of CR 21 through the western edge of Cathedral Pines County Park. The route of CR 8 was to have started at the intersection of I-495 (at EXIT 66) and CR 101 (Patchogue-Yaphank Road). Originally planned in 1973, CR 8 shelved was for many years due to lack of funds.
