Just when you think the Erie Canal Trail restoration work is done... the Canal Corp Rehabilitation workers add their final touches... Trail Edge
Here's what the ECT Trail Edger looked like... seems like they are using standard highway construction equipment

And a nice collage of the process to add a stone dust retaining edge to the ECT... which if you didn't know it is REALLY an Embankment Dam Inspection & Service Road

And instantly the restored Canal Trail is made even that much better

Here is a GREAT video of the process to add trail edge support taken "drone style"
