The M60 provides service between the Upper West Side of Manhattan and LaGuardia Airport in East Elmhurst, Queens, traveling between boroughs via the RFK-Triborough Bridge.

At 94th Street, the M60 turns north and enters the airport, serving Terminals B, C, and A (in that order) before returning to Manhattan.

[11] The M60 was approved for implementation in mid-1992[12] and began service on September 13, 1992, running between Adam Clayton Powell Jr. Boulevard (Seventh Avenue) and the airport.

[16][17] The route was extended in response to requests from residents and groups from Morningside Heights and West Harlem.

[28][29] A separate outside study in 2011 by the Regional Plan Association proposed creating dedicated busways along the Grand Central Parkway to speed up M60 service.

[32] According to the city government, the three routes" would provide "shorter term, lower cost transit improvements" for LaGuardia Airport.

[33] Studies and community outreach for Select Bus Service upgrades were conducted through 2011, and plans to implement the M60 SBS were announced on October 11, 2012.

The plan would turn the M60 local into a limited-stop service along 125th Street, with the number of stops along the corridor reduced from eleven to six.

It would add dedicated MTA bus lanes and other improvements to speed travel times, and make the fleet entirely articulated and fully equipped with luggage racks.

[7][8] Plans for the SBS route were scrapped in July 2013 after opposition from the Harlem community and state senator Bill Perkins, over the potential loss of parking space on 125th Street, and due to a lack of collaboration by the DOT with the community.

[38]In January 2023, the MTA released a strategic action plan called "Extending Transit's Reach".
