Written Directions
Taking this road from Waynesburg, PA means heading out of Waynes on 21 West, making a right onto 18 North, taking 18 North to 231 North.
Taking this road south means getting to Avella, PA which is on Route 50 near the Ohio border. From there take 231 south. Of course, it is always possible to pick 231 up on 331, 40 or I-70, but Avella gives you the full experience straight south.
Scenery
Just like it's sister road 221, 231 has your typical farmland with hills sights. Nothing boring, exactly, as some of the road has no guard rail and I pity the fool that end up over a big hill from missing a turn, but the views aren't breath taking, either. A bit above average for this area of PA.
Drive Enjoyment
More so than 221, 231 likes to be traveled by big dump trucks that leak some stones or drag stones off of their Marcellus Shale sites onto the road. It doesn't make the road treacherous, by any means, but you will want to pay attention. The pavement it's self is sort of a patchwork job with some pot holes, it could be better...but it could be worse.
Tourism Opportunities
None on the road. Get your gas and food at one of the destinations or while passing US 40 or I-70. I know of no landmarks.
Motorcycle Road Additional info
This road makes a great loop with Route 221, but the loop I use is a lot bigger than the one listed on this site. I take the whole of 221 and 231 using 331 and 18 as a connector, this gives you the whole experience. Nice decent sprint that loop is.
