Design Construction Plans
This website is intended to provide design construction plans in PDF form. You will need Adobe Acrobat to open these files. Each file varies in size from 400KB to over 2MB. Your internet connection will determine download time. Use the below search to find the corresponding PDF for the resulting location, or use the interactive GIS tool to locate specific PDF from a specific area.
NOTE: Only a very limited selection of Highway plans are available using the interactive map search tool. For better search results, use the text based search on the left.

Thomas Guide
Thomas Guide is a grid layout representation of geographic areas. It consists of a numeric page.
 

Highway Search Tips:
  1. Try multiple searches with different street name spellings, or partial entries for a street name.
  2. Search for the names of intersecting streets.
  3. Leave Drawing Limits/Location blank for broader results.
  4. Leave Thomas Guide blank for best results when searching for older plans. Most older plans do not have Thomas Guide indexing.
