distinguish between abutting line features with same color symbolization??

I am struggling with a symbolization challenge. I have a line shapefile depicting construction projects along a roadway centerline. The projects are color coded based on their attributes, and oftentimes two abutting projects wind up same color. It becomes impossible to tell where one ends and the other begins. I???ve included an example with two such projects, but I???ve taken the liberty to make one of them a lighter shade of green.

My initial idea was to place a thin grey border around each project. I did so by duplicating the project layer, symbolizing it grey, setting the width slightly wider, and placing it behind the primary layer. This doesn???t work???but I do like how the thin line helps the projects stand out from the map???s background.

Does anyone have any suggestions?
