Found this one as marked. As you can see in my photos. This one will not be around for much longer. You can see that the concrete is being eaten away, I guess by salt and weather. So I was happy to find it before it is completely gone. The bridge is in bad shape and will at some time be replaced. I think being in service since 1920, it has seen it share of traffic...

Not too hard to find. It was actually visible from the car.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
