Editing Bronx River Parkway (section)

===Westchester County===
Once across the county line the parkway is in [[Yonkers, New York|Yonkers]], close to its boundary with [[Mount Vernon, New York|Mount Vernon]].<ref name="Yonkers-Mount Vernon Line">{{Google maps|url=https://www.google.com/maps/place/Yonkers,+NY/@40.9187341,-73.8542693,14z/data=!4m2!3m1!1s0x89c2c0080943afa1:0xbe967384a4d8daa2|access-date=4 October 2014}}</ref> A southbound exit, 10C, serves [[Bronx River Road]] at Wakefield Avenue near [[Wakefield (Metro-North station)|that train station]] a quarter-mile (500 m) north of the county line, even though the station is in the Bronx and the Harlem Line enters Westchester north of it.<ref name="Wakefield Station">{{Google maps|url=https://www.google.com/maps/@40.9054499,-73.8552014,17z|access-date=4 October 2014}}</ref> Northound traffic has 10A, for Mount Vernon Avenue and [[Yonkers Avenue]] at the [[Mount Vernon West (Metro-North station)|Mount Vernon West]] station three-quarters of a mile ({{convert|0.75|mi|disp=output only}}) to the north.<ref name="Mount Vernon West Station">{{Google maps|url=https://www.google.com/maps/place/Mt+Vernon+West/@40.9116588,-73.8521515,17z/data=!4m2!3m1!1s0x89c2f2c84e7c5449:0x38078614c9663161|access-date=4 October 2014}}</ref> Another southbound exit, 10B, serves Bronx River Road just to the north at its Mile Square Road and Winfred Avenue intersections.<ref name="exit list southern half of parkway"/> The park widens around the highway as it bends slightly, heading even more to the northeast. Just past this is exit&nbsp;11, the [[Cross County Parkway]], where the road swings toward the east to allow space for the complex of onramps that also allow access to Broad Street and the [[Fleetwood (Metro-North station)|Fleetwood]] station.<ref name="Cross County Parkway Interchange">{{Google maps|url=https://www.google.com/maps/@40.9265351,-73.8480476,15z|access-date=4 October 2014}}</ref> A half-mile north of that junction, the parkland and the roadway narrow as [[Bronxville, New York|Bronxville]] becomes the community on the opposite side of the Bronx River.<ref name="Bronxville-Yonkers Line">{{Google maps|url=https://www.google.com/maps/place/Bronxville,+NY/@40.9379967,-73.8290144,15z/data=!4m2!3m1!1s0x89c292a520434627:0x634a3a859ebe5561|access-date=4 October 2014}}</ref>

The parkway reaches an interchange with the southern terminus of the [[Sprain Brook Parkway]] and becomes a four-lane [[limited-access road|expressway]], turning sharply to the northwest, away from the Harlem Line. The exit numbers reset here; the new exit&nbsp;1, Paxton Avenue in Bronxville, is on the northbound lanes just north of the Sprain (exit 1A allows southbound traffic to leave the parkway for Desmond Avenue just before merging). Exit&nbsp;2, West Pondfield Road, also northbound-only, is a thousand feet (300 m) to the north as the highway curves around downtown Bronxville to the east. Here, the road runs through the [[Armour Villa, Yonkers|Armour Villa neighborhood]] until it runs under the Tuckahoe Road bridge. Almost a mile (1.6&nbsp;km) separates it from the next exit, at Elm Street in [[Tuckahoe, Westchester County, New York|Tuckahoe]]. The park continues to parallel the parkway, with paved [[bike path]]s and a large pond. A thousand feet to the north, Scarsdale Road is the first at-grade interchange, and the parkway turns sharply to the east, then back to the northeast more gradually. Exit&nbsp;8, Thompson Street, serves the nearby [[Crestwood (Metro-North station)|Crestwood]] station as the Harlem Line's tracks begin to parallel the road again. Another three-quarter mile north, after the road has resumed its northeast course, comes the next at-grade exit, Leewood Drive, on the northbound side.

A quarter-mile (500 m) to the north are abandoned parking lots on both sides that were once gas stations. {{convert|1/10|mi|m|adj=pre|of a|spell=In}} to the north, the roadways diverge and the river runs between them. Just beyond this is another at-grade interchange, Harney and Strathmore Roads. The roadways remain apart through a wooded section as they curve westward for the next three-quarter mile, returning to the highway's northeastern heading as it leaves Yonkers and briefly enters [[Greenburgh, New York|Greenburgh]] south of the southbound Ardsley Road exit east of downtown [[Scarsdale, New York|Scarsdale]]. Just after it curves eastward again and crosses the Harlem Line, entering Scarsdale, traffic can enter and exit at Crane Road and East Parkway with southbound traffic using a light to cross over the northbound lanes and no entrance onto the southbound lanes. In the next {{convert|2.2|mi|adj=on}} stretch, there are exits for Ogden and Butler Roads from the northbound lanes. Fenimore Road, just east of the [[Hartsdale, New York|Hartsdale]] and its [[Hartsdale (Metro-North station)|train station]], is a northbound exit with southbound entry. Just to its north, southbound traffic can exit onto Greenacres Avenue. The parkway begins heading even more to the northeast, the tracks immediately adjacent, past northbound exits for River and Claremont roads.

Just north of the latter exit, the highway enters [[White Plains, New York|White Plains]], the Westchester [[county seat]]. After the northbound Walworth crossing exit, it turns northwest across the river and the tracks and then resumes its northeasterly course. A half-mile (1&nbsp;km) north it reaches the Main Street ([[New York State Route 119|NY&nbsp;119]]) northbound exit/southbound entrance, just west of the [[White Plains (Metro-North station)|White Plains]] station on the west side of heavily developed downtown White Plains. It bends north and then northwest to the first of several at-grade intersections with traffic lights, also signed and numbered as exits, with Central Avenue ([[New York State Route 100|NY&nbsp;100]]), at the [[Westchester County Center]]. From here, parkway traffic is also directed toward the nearby Cross Westchester Expressway ([[Interstate 287|I-287]]) via NY&nbsp;119, as the parkway has no direct interchange with it.

The two roadways once again diverge, becoming almost {{convert|400|ft}} apart in the half-mile (1&nbsp;km) before they converge again as they reach the Old Tarrytown Road intersection just north of the expressway. Beyond it the parkway goes due north before curving slightly into the Fisher Lane intersection just west of the last Metro-North station along the parkway, [[North White Plains (Metro-North station)|North White Plains]]. The Parkway Homes and Virginia Road intersections follow, spaced roughly a thousand feet (300 m) apart. Another thousand feet from that intersection, the highway turns to the northeast again as the roadways diverge and cross the Harlem Line and the Bronx River for the last time. Northbound traffic has the last exit, exit&nbsp;27, onto Washington Avenue North. [[Kensico Dam]] is visible in the distance as the parkway reaches its northern terminus at Kensico Circle, southern terminus of the [[Taconic State Parkway]], also listed on the Register.

A seven-mile (11&nbsp;km) section of the Bronx River Parkway in Westchester County south of White Plains is closed to motorist traffic from 10 AM to 2 PM select Sundays in May, June, September and October (with the exception of Memorial and Labor Day weekends), allowing [[bicycle|bicyclists]] to venture along the scenic road. Another section north of the one reserved for bicyclists is reserved for [[inline skating]].<ref>{{cite web | url=http://www.mylivingfit.com/2010/05/bronx-river-parkway-bicycle-sundays/ | title=2010 Bronx River Parkway Bicycle Sundays : LIVING FIT Personal Training-Fitness, Nutrition and Weight Loss, Stamford, CT }}</ref> This program is sponsored by Con Edison and NewYork-Presbyterian Hospital.
