 Browncroft Boulevard was upgraded into a four-lane divided highway between the Sea Breeze Expressway (NY 47) and Blossom Road during the mid-1960s. Some parts of the highway were upgraded on the spot; others were bypassed and are now known today as Old Browncroft Boulevard. As a result of the upgrade, the alignments of NY 286 and NY 286A west of Blossom Road were flipped, placing NY 286 on Browncroft Boulevard and NY 286A on Blossom Road. The NY 286A designation was removed in the early 1970s and replaced with NY 941V, an unsigned reference route 2.20 miles (3.54 km) in length. Reference markers along Blossom Road still read "286A".
