16 Midtown Crosstown

4.54 mph baseline, weighted so busier routes count more (the pre-plan year)

−1.6% July 2026 vs July 2025 (4.63 to 4.55 mph). Pre-plan months on these routes swung −6.9% to +0.3%. Too soon to call.

No segment-clipped baseline: this is a conceptual corridor without a single named street, so the route-level view is the score.

Routes on this corridor

Route	Baseline mph	Riders/day	Full-run time (derived)
M42	4.65	7,273	27.6 min full run
M50	4.5	1,869	32.5 min full run
M57	4.4	5,251	39.7 min full run

Full-run time is derived: route length divided by average speed. Rider counts are fare-paid boardings, weekdays 7am–7pm, on tracked local routes. The plan's own rider figures count all riders, all day, so they run higher.

What the plan says happens here

The plan lists no work here for 2026; this corridor is scheduled as a future project.

How this corridor was mapped to routes

A future project no source has scoped to routes. The M42 and M50 are the crosstown routes inside the plan map's arrow, which spans West 57th/12th Avenue to East 42nd/1st Avenue; the M57 was added on July 11, 2026 because the arrow reaches 57th Street. This mapping is explicitly provisional until DOT scopes the project. (Verified July 11, 2026; corrections welcome.)
