Description   EN   

Built in 1869, the Bollman Iron Truss Bridge, spanning the Little Patuxent River, is the sole surviving example of the bridging system invented, 1850, by Wendel Bollman, a Baltimore engineer. It was the first system, entirely of iron, used by the Baltimore and Ohio Railroad and was the first in America. The company built about 100 such bridges through 1873.

In 1966, under a new program of the American Society of Civil Engineers, it was designated the first ever Historic Civil Engineering Landmark. The bridge was listed on the National Historic Landmark on December 18, 1972, and was designated a National Register of Historic Places on February 16, 2000.

When I was in middle school, I lived nearby and used to enjoy exploring the bridge, nearby ruins, and the river. I hope you enjoy the site, as well.

Logging Requirements:

From the posted coordinates, you will find some plaques. You need to find a four digit number on a blue background. This will serve as the LOG PASSWORD.  You must also post a picture of yourself and/or your GPS with the bridge.

Interesting pick for the password, almost missed that!  Was our doing a 10K hike and this was right on the path, so it was a quick find.

A nice historic location. I love old bridges. This one is nice to see in that it's the only of it's kind remaining.

I was in this area on this cold morning before the snow hits, and remembered that I'd seen this listed, so came back by to get the password and the picture. I've been to this park many times to cache, and always enjoy seeing this historical landmark. I hope to see more like these in the area. Thanks for bringing back to this park!
