The Bronx The parkway begins at Story Avenue in the neighborhood of Soundview in the Bronx, where two roadways merge near Metcalf and Morrison Avenues. Immediately to the north is the cloverleaf interchange at the Bruckner Expressway (Interstate 278 or I-278), where most traffic enters the parkway, which begins as a six-lane freeway. Basketball courts and baseball fields flank the highway in the strip of parkland as the road leads to the north, slightly northwestward. North of Watson Avenue, within a half-mile (1 km) of the southern terminus, an on-ramp carries northbound traffic from Metcalf. The corresponding offramp for southbound traffic merges onto Harrod Avenue north of Westchester Avenue. thumb|Signage at exit 6 for the Bronx Zoo on the southbound side. (I-895 has since been redesignated NY 895) Now in West Farms, the Bronx River Parkway has an onramp to the southbound lanes from East 174th Street. North of it is exit 4, the interchange with the Cross Bronx Expressway (I-95). The single ramp of exit 5 allows southbound traffic to follow East 177th Street to NY 895 (Sheridan Boulevard) and the Triborough Bridge. North of the interchange the road veers to the northeast slightly and crosses the railroad tracks of Amtrak's Northeast Corridor line. At East 180th Street, the linear park ends temporarily. The road becomes elevated to cross the East 180th Street Yard along the New York City Subway's IRT White Plains Road Line, which carries the , as well as the former New York, Westchester and Boston Railway. After crossing the yard, wooded surroundings resume as the parkway follows the eastern edge of the Bronx Zoo in the Bronx Park neighborhood and the Bronx River, which gives the road its name, begins to follow it on the west. On the northbound side, as it enters the park, is an unnumbered exit allowing authorized vehicles (like those of people working at the NYC Parks Department) access to local streets via Birchall Avenue. left|thumb|Bronx River Parkway southbound at exit 10C A quarter-mile to the north is the main exit for the zoo at Boston Road, with access to Boston Road (U.S. Route 1 or US 1 northbound) for northbound traffic, then the full cloverleaf at Pelham Parkway, where traffic can join US 1 southbound on Fordham Road. Past the exit the large wooded area on the west is the New York Botanical Garden, a National Historic Landmark (NHL). One half-mile (1 km) further north, exit 8 allows access to the Mosholu Parkway and Allerton Avenue. At the next exit, Gun Hill Road, the Williamsbridge station serving that neighborhood on Metro-North Railroad's Harlem Line, which closely parallels the parkway from this point on, is located immediately west of the highway. The railroad tracks join the river and the parkland in paralleling the road north as it continues straight along the east edge of Woodlawn Cemetery, another NHL.
