I went by Jones Point Park last weekend and despite the unnecessary, unwelcoming and possibly unsafe bollards, the park itself is pretty fantastic and represents a greatly improved destination along the trail.
Instead of running up the north side of the bridge and then crossing over to the south side, the MVT now goes in a more gradual diagonal direction underneath the bridge. This should make for an easier ride for those who are just passing through. In addition the trail now has a separate pedestrian section along part of it.
The waterfront has been vastly improved. There are now two fishing piers that give great views of the river, and a small boat dock. They've also added playgrounds and a lot of parking (way more than I suspect they'll ever need).
They've also taken quite a few steps to capture the history of the area. Those of you who've done WAGBRAD (probably not happening this year, I'm sorry to say) may remember that you had to jump down over a wall and a long the river to see the boundary marker that designated the southernmost point of DC (before retrocession of Arlington and Alexandria, now the southernmost point is a short distance away and at the water). But they installed a viewing window that allows you to look down at it.
They also added boundary markers alongside all trails and paths showing the historical boundaries between DC, Maryland and Virginia back before the Civil War. Which makes me wonder, did Maryland lose territory because of retrocession (the area on the SE side of this stone)?
During WWI the area was a shipbuilding dry dock and they found and displayed an old rudder from a ship that was built there. They also made the extant dry dock run (or whatever it's called) more visible and prominent. If you go, check out the photo of what the site looked like then.
They should take down the MVT detour signs in Old Town Alexandria, since they aren't needed anymore (they threw me off when I saw them and I followed the detour as a result). Maybe they already have.
And maybe all that parking could be put to use as bike-commuter parking. Drive in halfway, park and ride the rest of the way along the trail. Maybe even pay a small fee for a permit to reduce abuse and provide money for trail enhancements.
