Thanks for the response! I tried that, and it works great...but of course now I have a new twist.
Some of the construction projects cannot be dissolved into a single feature, because I need to uniqely symbolize different parts of the project. If I apply symbolization to the layer like you describe, I end up with a border around every individual feature within the project, instead of just around the overall project.
Here's another example with two construction projects.
Any takers?

Something like this? Where the green and purple are different parts of the same project? (I took the liberty of modifying your screencap.)

I found a workable solution:
1) Dissolve the original features on the construction project identification field. This yields two line features in the example above.
2) Buffer these features. In my example, I created a buffer 0.7 miles on both sides of the line, with round endcaps for each line.
3) Place this polygon layer on top of everything else, and symbolize it with no fill and a thin grey outline.
The polygons/buffers do overlap (as I've shown below), and I haven't decided how to best address that...but for now this is a start. If I come up with something I'll post here.
