The Q25 and Q34 bus routes constitute a public transit line in Queens, New York City.

Between the Whitestone Expressway and Jamaica, the Q25 employs limited-stop service, making intermittent stops primarily at major intersections and points of interest.

The Q34 begins at the intersection of Willets Point Boulevard and 149th Street in Whitestone, and continues down Willets Point Boulevard when it merges onto Union Street, where it briefly shares 1 stop with the Q44 SBS and 2 stops with the Q20A/Q20B.

[14] On April 20, 1933, the New York State Transit Commission (NYSTC) granted the Flushing Heights Bus Company a certificate of convenience and necessity for operation of a Flushing-Hillcrest route via Parsons Boulevard.

While the company had sought a route between Flushing and Jamaica, it was restricted on its southern end to 75th Avenue and Parsons Boulevard due to the opposition of the New York and Queens Transit Corporation, which operated a competing trolley route along 164th Street.

[citation needed] In 1940, Queens-Nassau Transit applied to the NYSTC for permission to modify its franchise for the Q25 so it could make a slight adjustment to its route.

This would eliminate the detour in Hillcrest of buses turning off of Parsons Boulevard at Goethals Avenue, then moving onto 164th Street, and then finally onto the Grand Central Parkway service road before moving back onto Parsons Boulevard.

[12] On March 12, 1945, the New York State Public Service Commission granted Queens-Nassau Transit Lines permission to discontinue a section of the Q25 along 88th Avenue between 153rd Street and the old trolley right-of-way.

[11][30][31] On July 9, 2007, Q25 limited-stop service was introduced, skipping stops between Flushing-Main Street and Jamaica during rush hours.

This was done in response to community requests to address buses that were double parking during their recovery times.

The turnaround path was changed to utilize 25th Avenue to northbound 150th Street to westbound Willets Point Boulevard.

[3] The community requested that the Q34 be removed from 25th Avenue, which abuts Leonardo Ingravallo Playground and the Memorial Field of Flushing ballfields to the south, and residential homes to the north.

The last northbound stop was relocated within the same intersection, and the turnaround path was reduced by approximately 1,000 feet.

[3] In December 2019, the MTA released a draft redesign of the Queens bus network.

The Q25's northern end would have been truncated to Linden Place in Whitestone; service to College Point would have been replaced by an extension of the Q17 bus.

[54] On January 29, 2025, the current plan was approved by the MTA Board, and the Queens Bus Redesign will go into effect by Labor Day.
