Routes on this corridor

RouteBaseline mph Riders/dayFull-run time (derived) Trend
M11 5.19 8,221 90.5 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

How this corridor was mapped to routes

The plan's card (p. 21) names the M11 outright: the 9th Avenue redesign from 32nd to 50th Street, citing 15,000 riders. (Verified July 11, 2026; corrections welcome.)
