Best route by far is direct line under pavement. Plan was to trench and put a sleeve in . Customer would take care of pavement after trenching and pipe install. Heavy trucks use the pavement. Boring is not an option.
I have been told here that regular trenches like a Dingo need special teeth for pavement. Ditch Witch says they have a 50 hp model that will do the job. $700 for the rental. About 100' total to be trenched.
Rent a walkbehind concrete cutting saw. It will give you clean lines unlike that trencher you are trying to rent. Then dig by hand and install your pipe. The clean lines from the concrete saw are going to make the patch of a pavement look a lot cleaner when you are done.
