Travel Time Between the Bronx and Brooklyn: Zero—They're Both NYC Boroughs

The Bronx and Brooklyn are both boroughs of New York City—not separate cities. They share a land border (via the Harlem River and several bridges).

There is no "travel time between them" in the inter-city sense. You simply cross a bridge or take the subway:

• Subway: 20–40 min (e.g., 4/5/6 from Bronx to Brooklyn via Manhattan; B/Q/D from Bedford Park to Atlantic Ave)
• Car: 15–45 min depending on bridge (Willis Ave, 145th St, Macombs Dam, Triborough) and traffic
• Bus: Bx12 SBS → subway; or express buses

Think of it as traveling within NYC—not between cities.
