Pentagon "desire path"

[lordofthemark]

So in a fit of exploration, I attempted to ride up the "desire path" or "scofflaw trail" that connects the end of the side trail from the MVT just south of the humpback bridge, to Boundary Channel Drive by the Pentagon parking lot.

It was a few inches wide (I was worried about poison ivy from the encroaching vegetation - maybe this is better in winter?) relatively steep grade in parts, and sloped off to the right. I ended up walking my bike for most of it, and only got back on for the "good" part, the ride on the grass along Boundary Channel.

A. Who uses this? Mountain bikers looking for a quick adventure?

B. What is the point of the stub end paved trail? Was there at one point a plan to extend that to Boundary Channel? Is there still?

I don't know who uses it. I didn't think anyone really used that path, but maybe a few hardy souls do.

I guess the stub trail was added because it was easier to build in conjunction with the MVT improvements at and near the Humpback Bridge, when all of that was rebuilt and improved a couple years ago. Arlington has long wanted to extend that trail from the Humpback Bridge, along the Pentagon Lagoon and over to Boundary Channel Drive. The DOD has denied requests to allow the trail to be extended, for vague security reasons. There's a small structure next to the lagoon, but a trail could easily be built outside of the fence.

The security argument doesn't seem convincing to me. The security isn't tight in that area. Anyone can just as easily drive, ride or walk on Boundary Channel Drive, next to the small building. The fence isn't that high either. If the building were so vital, then why doesn't the Pentagon have better security for it? It's also pretty easy for someone in a small boat from the marina to ride right up to that building. I don't know what the building houses.

Anyway, I think Arlington convinced the powers that be (FHWA, NPS?) to build that stub, or they may have done it themselves, as a hint to the DOD that there is demand for the trail extension. It's up to DOD whether or not the trail is ever completed. Arlington still wants to complete the trail, but they haven't received DOD permission to proceed yet.

I presume you have taken the other trail that goes under Humpback Bridge to Columbia Island and taken the bridge over to Boundary Drive? It's a little longer than the desire path but at least it is all paved and legal.

There is some hope that the Boundary Channel Drive Interchange project will get the trail far enough away from the Pentagon that they'll allow it. We'll see.

When Arlington negotiates with DoD (e.g. re: ANC and Columbia Pike near 395), do they bring up all of these issues? Or is there at least a strategy beyond asking, one off, "please, we'd like this little thing"? There are a number of issues that impact cyclists (I'm thinking this, bike access to Fort Myer, bike access to ANC, I'm sure there are others) that I'd hope could be solved with a more coherent strategy.

The relationship seems strained at the moment, with the on-again/off-again deal for the land swap at Columbia Pike/Southgate Road/Navy Annex. The two sides announced an agreement, or an agreement to have an agreement, but then it fell apart.

I would think that Arlington brings up issues more than once, but I don't know how often they meet with DOD.

Can somebody map this on google maps for me - I'm struggling to figure out just where this trail is.
I'm working on my route selection from DC to crystal city and the regular MVT-->LBJ grove-->Columbia Isl. Marina Bridge-->Boundary Channel Dr-->Long Bridge Dr-->Crystal City route is fine, but the LBJ grove detour is a bit out of the way and the current state of Long Bridge Dr. is AWFUL (although it looks like it will be repaved within the next few weeks)

Here you go

If you take the downstream tunnel under the Humpback Bridge, you will be on a trail between the lagoon and I395 until the trail ends. I posted some pics a while back and I'll post that link if I successfully locate them

I don't know if I'd recommend riding through there.

Here are some photos. They were taken in June 2012

You can see the tunnel under the Humpback



The trail continues parallel to I395. You can see the interstate signs in the photo below



And then it just dies.



The little building on the south side of the lagoon (you would encounter it if you continued on the desire path) has a number of signs suggesting it is a secured building and discouraging photography
