Routes on this corridor
| Route | Baseline mph | Riders/day | Full-run time (derived) | Trend |
|---|---|---|---|---|
| S81 | 12.38 | 108 | 37.3 min full run | |
| S51 | 11.4 | 1,453 | 50.4 min full run | |
| S74 | 11.6 | 1,968 | 142.0 min full run | |
| S76 | 9.96 | 1,435 | 66.7 min full run | |
| S78 | 12.36 | 2,579 | 168.7 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.

How this corridor was mapped to routes
The S51 and S81 run Bay Street proper; the S74, S76, and S78 funnel along its densest stretch into St George. School-day limited variants are excluded. (Verified July 11, 2026; corrections welcome.)
