The route becomes a commercial arterial after the viaduct, bending northward into a large at-grade junction with NY 107 (Broadway) next to the Broadway Mall. The two routes become concurrent, proceeding northwest through the Jericho Gardens section of Oyster Bay. Like Newbridge Road, Broadway is also a divided highway, passing through a large commercial district in Oyster Bay. Passing a local casino northbound, NY 106 and NY 107 enter exit 35 of the Northern State Parkway. Immediately after crossing over the Northern State, the routes enter an interchange (exit 41) of the Long Island Expressway (I-495). After crossing over both roadways, NY 106 and NY 107 are now in the East Birchwood section of Oyster Bay, proceeding northwest as a four-lane divided commercial arterial.
