Expert Tips for Navigating the M101 Route
Maximizing your commute efficiency on the M101 requires insider knowledge of NYC surface transit quirks and traffic patterns.
- Leverage Transit Apps: Avoid relying solely on static schedules. Utilize real-time GPS feeds to track bus spacing, as bunching frequently occurs along Lexington and Third Avenues due to double-parking and delivery trucks.
- Understand the Couplet System: Remember that southbound buses run down Third Avenue, while northbound buses travel up Lexington Avenue. Walking one avenue over in the wrong direction will result in missing your ride.
- Utilize Bus Lanes: Municipal bus lanes along these avenues are camera-enforced 24/7. While this significantly speeds up transit times compared to general traffic, severe gridlock near major bridges and midtown cross-streets can still cause delays.
