The Madison corridor, from Colman Dock to 23rd Avenue, has grades that are simply too steep for conventional streetcars. The $81m BRT option is more efficient, according to ANC/NR, than the cheaper enhanced bus option ($2.96 vs. $4.16 per rider). Both values are middling for the study as a whole. The ridership difference is small – 14,000 vs. 12,500 weekday riders in 2030.
The BRT option would save about 8 minutes for travelers going end-to-end. It is both relatively cheap to max out and the one truly east-west HCT corridor. In either alternative, the this line replaces the 11 and 12, but buses at the end split between heading to Interlaken Park or Madison Park.
