How longs does it take to horseback ride from new haven to philadelphia in 1776

If I wanted to ride my horse from Boston to Philly in 1776 how would I know how to get there? I assume they had some kind of maps. Did the dirt roads/trails have signs to point the way? I assume there was 1 main road that connected the major cities back then so maybe it wasn't that hard to follow.
