Good choice - Bridge #1 is correct
How
do I know? One of the news articles on the web has a tiny picture of the bridge
with a white building in the background. This is the only bridge next to a
white building. The building was painted green in 2007. This is not the bridge
that was shown in the movie 'Breach'.
Take
a look at the bridge from the side to see how a package could be easily left
under the bridge.
Take
a look from the other side of the bridge near the white building. Notice that
several houses overlook the park and can easily observe the bridge. The advantage
of this location is that it is close to a road with a sidewalk and can be
accessed while taking a casual stroll.
This
is the sign where tape was placed to indicate that the material had been dropped
off. The sign is across the street from the bridge that was used. This is
the sign that appears in the movie 'Breach'. Robert Hanssen would not have
walked down this trail to reach the actual bridge that was used.
Congratulations on locating the scene of the crime.
