The 11th Avenue segment would be:
* Northbound from Madison to Denny with the Two-Way Broadway option;
* Northbound from Union to Denny with the Boren option;
* Southbound from Denny to Union with the Broadway-12th couplet option.
I have a call into SDOT asking about the reason for the couplet as well as how it will affect travel time and if this means that the streetcar might enjoy some level of exclusive right-of-way. Later today I should be receiving detailed maps of the different alternatives so look for an update sometime later today.
UPDATE: Ethan Melone just got back to me. His response to my questions are below. I also just received maps and images for tomorrow meetings and I’m in the process of uploading them.
Q: Are the alignments the same besides the 11th Ave segment?
A: Yes, the alignments are otherwise the same south of Union or Madison street.
Q: Why 11th?
A: 10th does not continue through to the light rail station, because of Cal Anderson Park and Bobby Morris Playfield. 11th provides an opportunity to loop around the park to the terminus station. This loop has several advantages including:
- simplest and most efficient turnback option for streetcar service;
- easier to avoid bike conflicts with tracks in only one direction on Broadway between Madison and Denny (see proposed roadway section on forthcoming drawings);
- improved reliability with only one direction of travel impacted by traffic congestion in this section of Broadway;
- reduced construction impacts;
- fewer utility conflicts.
Q: Does this mean there will be any exclusive ROW?
A: We do not see this as exclusive right-of-way from Denny to Union. It might be exclusive from Madison to Union or possibly Madison to Pike.
Q: How will this affect travel time?
A: The travel time is estimated to be the same as, if not shorter than, two-way on Broadway in this segment. We have not taken into account yet the travel time savings that might be possible if we provide signal priority at 11th & Pine and 11th & Pike (the latter would be a new signal).
