A short distance later, the two roadways enter an unnumbered cloverleaf interchange with NY 25 (Jericho Turnpike). After crossing under NY 25, NY 107 continues north along Cedar Swamp Road, while NY 106 bends northeast via an at-grade junction on Jericho–East Norwich Road. NY 106 remains a four-lane divided boulevard, passing north for a short distance through Muttontown and passing east of the Muttontown Preserve. Changing monikers to Jericho–Oyster Bay Road, NY 106 continues north before making a gradual bend along the preserve to the northwest, re-entering Oyster Bay. After crossing back into Oyster Bay, the route becomes residential going southbound before intersecting with NY 25A (Northern Boulevard).
