At the merge, the Sprain Brook, a wider road with three lanes in each direction, a mostly cleared median strip and shoulders on either side, becomes the Taconic. For the remainder of Westchester County, the Taconic has been rebuilt, widened, and modernized to meet the needs of commuter growth, bearing little resemblance to its original design. A thousand feet () to the north, after a small interchange with NY 141, a three-level stack interchange allows access to the Saw Mill River Parkway northbound (and southbound from the southbound lanes). North of the interchange power lines and Saw Mill River Road (New York State Route 9A or NY 9A and NY 100) on the west parallel the parkway past undeveloped Graham Hills County Park. The next exit, at Bedford Road (NY 117), serves Pleasantville to the east. Just north of it, a short fork allows traffic to divert to NY 9A and 100, which split away toward Ossining.
