Coming from another investor who's been grinding towards similar goals, I can say it's not easy, so what you've done is inspiring! 

The higher the R-value, the greater the noise deadening.

Tune out the outside noise.

Put a disclaimer in your listing description that there is construction in the area and there may be construction noise during business hours. 

But I'm not sure if rental demand will also be lower due to the Interstate noise.

Most birds do not make noise at night, but there are a couple that do.

It's a grind to find them.

I pivoted, I grinded, I collaborated, I commiserated, and I figured it out. 

Then you grind off the last of it and much of the epoxy with a diamond grinding cup wheel and then do the last of it with a carbide rasp on an oscillating tool.

I would consider the following (which you may have already done):House rules say no gatherings (penalty of $X per person if violated)House rules say quiet hours are 10:00 PM - 8:00 AMIf profile has no reviews / not verified, require they confirm the # of people who will be at the property & agesUse a noise monitoring system like Minut or Noiseaware (disclose in listing)Use exterior cameras to monitor driveway (disclose in listing)But at the end of the day, there are still bad guests who will get through and sometimes you just have to file a claim, kick them out, apologize to neighbors, and get the place ready for the next group.
