One-half mile south of Kensico Plaza the parkway drive intersects with Virginia Road. This is an at-grade intersection controlled by traffic signals. Approximately a quarter mile south, at Mile Marker 12.5, the parkway drive intersects with Parkway Homes Road, another at-grade intersection with traffic signals. The bicycle path runs east of the road through wetlands and grassy meadows. Fisher Lane, another at-grade intersection with traffic signals, is located at Mile Marker 12.2. South of Fisher Lane, the road descends as it winds its way through the parkway. The drive is carried over the Bronx River by bridges with double box-beam guide-rail walls at Mile Markers 12.0 and 11.8.

At Old Tarrytown Road (Cemetery Road, Mile Marker 11.7), the parkway drive is divided. The southbound lanes are at a slightly higher grade than the northbound lanes. The drive passes under a recently completed large multiple-span steel girder bridge carrying U.S. Interstate 287. The parkway reservation from Old Tarrytown Road to the County Center is relatively wide, allowing for a variety of tree groupings in open meadows. With its grassy lawns framed by picturesque plantings, this area is one of the most classically park-like sections of the parkway. Saplings have been planted in some of the larger clearings and may eventually alter the broad vistas called for in the original landscape plans. South of the interstate, the northbound lanes are carried over the Bronx River on a bridge with box-beam guide-rail walls. Two rustic concrete arch bridges faced in stone carry the northbound and southbound lanes over Manhattan Brook. Immediately north of the County Center at Central Avenue in White Plains, the roadways pass over rugged boulder-faced bridges that cross Fulton Brook. Cortan steel box-beam barriers have been added in many places throughout this section to shield the original bridges and other potential traffic hazards. After the Fulton Brook crossings, the drive merges into a single four-lane roadway.

Approximately 2.5 miles south of Kensico Plaza, the parkway drive enters White Plains. The Central Avenue intersection is at-grade and controlled by a traffic light. On the northwest corner is the Westchester County Center, an Art Deco style concrete community building constructed in 1929. A stone-faced concrete arch bridge over the Bronx River opposite the Westchester County Center connects the parkway road and Central Avenue to the County Center parking lot east of the river. As the road proceeds south from the County Center, there is a large county parking lot on the west of the road, with a row of mature memorial trees commemorating World War I veterans from White Plains planted between the drive and parking lot. The Bronx River runs directly adjacent to the road on the east, although vegetation obscures it from view. The road is elevated above the river, and reinforced concrete barriers are between the river and the road at the approach to the Hamilton Street Bridge. South of the Westchester County Center, the road is divided by w-beam guide rail and is three-lanes wide. The fourth lane, the southbound right lane, serves as an exit-only lane into White Plains at the south end of the county parking lot.

South of the county parking lot, the parkway drive passes under the Hamilton Street Bridge, a modern structure constructed of steel-girders with stone-faced abutments. The road immediately passes beneath the Main Street Bridge, a more traditional rigid-frame concrete arch bridge faced in stone with a highly decorative parapet. There is an exit lane to Main Street from the northbound parkway drive and an entrance ramp from Main Street to the southbound parkway drive. South of Main Street, the drive widens back to four lanes at the Main Street entrance ramp.

South of Main Street, the road winds through heavily wooded areas. The road follows the reservation’s west boundary, which has a steep rise stabilized by original rock retaining walls. The railroad tracks parallel the reservation boundary on the east.

Woodland Place Viaduct, an open-spandrel concrete arch bridge rehabilitated in 1995, carries the drive over the Bronx River and railroad tracks near Mile Marker 10. A modern stone retaining wall along the west edge of the southbound lanes helps stabilize the steep bank above the northern end of the bridge where the roadway was broadened slightly to improve safety. The replacement parapet walls are reinforced concrete with a balustrade pattern that is reminiscent of the original design but has a shallower relief to improve safety. The viaduct’s roadbed is divided down the center lanes by a 4' to 5'-high reinforced concrete barrier that runs the entire length of the viaduct and extends on either end, from Mile Marker 10.2 to Mile Marker 9.8. Just beyond the south end of the bridge the southbound roadway is raised slightly above the northbound lanes, requiring a jersey barrier-style retaining/guardwall that poses an unsightly intrusion, especially to northbound motorists. This concrete barrier transitions to a two-sided steel w-beam median divider as the road curves south of the bridge approach. The viaduct is built on a tight curve with almost a 45 degree angle at each end. This configuration was inconvenient in the days of early automobile travel and has become more problematic as traffic speeds have increased. Motorists traveling in both directions are warned by a large yellow sign with flashing amber lights to reduce their speed to 20 miles per hour.
