 General Description:
 
   1:2000000 Arc Coverage of road system with Interstate Highway System 
identified. Coverage includes roads within the boundary described below 
with clipping along some state line segments. Coverage Boundary defines 
a rectangle encompassing the SAA Area.
 
        COVERAGE BOUNDARY

     Xmin =        -428494.531            Xmax =               361103.031
     Ymin =          10514.145            Ymax =               739719.000
  
 Intended Use:
 
   Coverage is useful for identifying the Interstate Transportation network in and around the SAA Area.
