Vessel Past Point Maps
Determine Vessel Traffic Past Point by County Maps
Locate the bridge site on the county map and note the color of the waterway at the location. The Legend at the base of the map shows the waterway color with the corresponding Past Point Number to use in the Mathcad file. To view the vessel
data, click on colorbar that matches the waterway color in the map legend.
Notes:
Small terminals or port facilities handling ships are not covered by the present catalog of vessel traffic characteristics. In these cases, on-site investigations
is required to establish the vessel traffic characteristics.
If a county does not appear in the list below, no designated Intracoastal Waterway or Inland Waterway goes through the county. If counties have a common boundary consisting of
a waterway be sure to look for both counties in the above list.
