    Default A Solution for Trollheim

    While on vacation at Chincoteague, VA, I traveled on a possible solution for our own diabolically slippery-when-wet Trollheim (the sheltered boardwalk between TR Island and Memorial Bridge on the Mt. Vernon Trail). I had long wondered about a concrete (pun intended) solution to this segment after observing how wooden railroad ties are being replaced with cast concrete ties. So...Click image for larger version.

    behold a stretch of "boardwalk" over salt marsh grass, part of the bike path and road over the channel to Assateague Island National Seashore. The planks are wider, true, but they got the color right, and there *is* a wood texture courtesy of the boards used as a mold, all to emulate wood. It has a grippy texture and looks to be safe to ride when wet.

    Now if the National Park Service says, "It can't be done", you can point and say, "You already have!"

    Saw another option in Chesapeake Beach, along the Bay. They have a short but pleasant rail trail that uses some sort of composite material (perhaps combining plastic resins & recycled wood, a la Trex?) that worked well for a long over-marsh stretch.

    So yes, there are multiple options that exist and are used successfully. Probably takes nothing more than money and momentum to move towards one of these....

    ...and the lobbying effort required to "demonstrate the need".

    I'm a big fan of composite, but it can be slippery.

    In any event, whatever the material, it would likely be not only better to ride on but more durable and require less maintenance and last much longer before needing replacement, which might justify the upfront cost. Of course, NPS/Congress may not care anyway.

    The composite deck is used at Kenilworth Aquatic Gardens for their boardwalks out into the marsh.

    The composite would likely be an improvement, however one of the biggest challenges on Trollheim is the angle of he turns. It doesn’t feel like it but you’re making two quick sharp angled turns. Add just a bit of moisture and boom.

    The bridge could use a realignment to make the split going southbound more of a drift to the left and less of a left turn followed by an immediate right turn.

    Money is certainly a barrier to doing this but a much bigger factor is that moving any part of the bridge would require some extensive bureaucratic processes, namely an environmental assessment.

    There is a composite or plastic plank example closer than that, right on Roosevelt Island itself.

    Not sure if it's the same material. The problem with this one is that, since the water doesn't soak in at all, it beads and pools up on the surface. That's pretty much okay for walking, but will still lead to slipping out for some bike tires, especially on turns.

    I ran on it for years though and don't remember it ever growing slimy alga-like films, so we'd have that going for us.

    On the slippery ART boardwalk near Bladensburg, God has installed a speed bump.
