Structurally Deficient Bridges

 This placemark collection contains data for approximately 70,000 bridges throughout the United States derived from the National Bridge Inventory Database 2006. The following fields were extracted from the database and are included for each placemark in the collection:

• State Code
• Route Number
• Latitude
• Longitude
• Year Built
• Kind of Material/Design
• Type of Design/Construction
• Condition of Deck
• Condition of Superstructure
• Condition of Substructure

This placemark collection only contains information on bridges with a status of "Structurally Deficient".  For a better understanding of the data, I suggest reading Coding Guide for the Structure Inventory and Appraisal of the Nations Bridges.

It’s a big file so give it a minute or two to load.

Description:

This collection of SuperOverlays contains all of the Aeronautical Sectional and Terminal Area Charts for the United States, including Alaska and Hawaii. These are based on high resolution digital versions of these maps produced by the National Aeronautical Charting Office. The maps in this collection are not current and must not be used for real-world navigation. They are for educational and simulation use only. I have just finished re-compiling these maps and they should now be the same quality as the original images.

Also included are 3D Airspace Polygons created by Lloyd Bailey. Again, these are not current.

Simply open the KML file linked above with Google Earth. Find the map you are interested in by checking the Index, then enable the map by clicking the box next to it under the Places menu in Google Earth Special Instructions:
