Essentially, yeah. Some of the smaller side streets might take awhile but as development spreads more overhead lines for cable, lights, and power have been buried. In some cases they've annoyingly been left up for various reasons. Like Race Street still having gooseneck lights because burying them would have added 300k to the streetcar budget. Which was the time to do it so now we may need to wait awhile before we see them buried.
Overhead wires are one of the best ways to cheapen an area and make it feel run down. Doesn't matter what's happening with the building stock. Even nice neighborhoods look bad when the overhead tangle of wires still exists. They wouldn't be so bad if the poles were nice and the wires were all organized neatly, but that's not the case. Dormant lines are left up, buildings connect into lines haphazardly, power lines have their insulation hanging down and falling off in pieces, etc. It looks like crap and is an insult to the people who live underneath them. We're one of the only first world countries that doesn't bury all of our utilities and it's something visitors notice.
