this street is now filled with houses on either side, and there are two more roads east before 25th street that need to be added with houses there as well.

North / south segments would be avenues.

There is a school zone here that reduces the speed limit to 15 mph. This could be implemented as a conditional restriction (something like "maxspeed:conditional=15 @ (Mo-Fr 08:30-15:30;PH off;SH off)"), but I'm not sure what the school hours for North Sargent are.
