Mark Destroyed 11/11/2012 Osprey2 marked JU0361 as destroyed   Visit Log

The disk is gone now. The new high-rise bridge and causeway that was built nearby is now completed and the old bridge has been demolished.

This is during demolition of the old bridge. It was taken from about where the mark was formerly located.
Found it 01/09/2012 Osprey2 found JU0361   Visit Log

It's still there but not for long. I had wanted to log this one in the past but there was always too much traffic on the bridge to get to it safely. The old road and drawbridge were recently abandoned once the new elevated roads were opened and now you can walk right up to it. The old bridge will be demolished by this summer and this one will be history.

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.
