Outlines of areas mined for the Wade Coal in Illinois. Mining in this seam ceased ca. 1940. This information was extracted from detailed coal mine data stored in the ISGS Coal Section library database. Lines delineate the approximate outer boundary of individual mines (if known) or general mined areas. Interior mine boundaries such as pillars or small blocks of unmined coal are commonly not depicted. Outlines have been compiled from a variety of sources. Outlines of areas mined before 1987 are commonly from source maps at scales of 1:62,500 or smaller. Outlines of areas mined since 1987 are commonly digitized at scales ranging from 1:4800 to 1:12,000. Mines whose extent is not known or which only mined a few acres are not included in this coverage. Additional information is available from the Coal Section of the Illinois State Geological Survey. Mine outlines from completed Coal Mine Quadrangle Studies were included in this feature class if applicable. An ongoing study, the detailed Coal Mine Quadrangle maps depict the best-known position of mine boundaries with respect to individual properties as located on a USGS topographic map image base. For a list of completed quadrangles please visit the ISGS Coal Section website or contact the Coal Section. This datafile was compiled and updated in 2014 in order to provide a current, state-wide data set showing surface and underground coal mines of the Wade Coal. Due to the wide range of source map scales, these data are suitable for regional applications only at the 1:100,000 scale or smaller.

Permits are issued for all loads that exceed the current legal limits specified by state law. The permit process ensures that inter and intra state commerce needs are considered while ensuring the protection of the state's infrastructure.

Designated Truck Routes - State Jurisdiction Truck Route.  Permits are issued for all loads that exceed the current legal limits specified by state law.

Highway Designations. The Department of Transportation may designate streets or highways in the system of State highways as follows:

  • Class I highways include interstate highways, expressways, tollways, and other highways deemed appropriate by the department.
  • Class II highways include major arterials not built to interstate highway standards that have at least 11 feet lane widths.
  • Non-designated highways are highways in the system of State highways not designated as Class I or II, or local highways which are part of any county, township, municipal, or district road system. Local authorities also may designate Class II highways within their systems of highways.

This feature class shows the distribution of areas that contain one or more sinkholes throughout the state of Illinois. Areas that contain sinkholes are susceptible to aquifer contamination and may also lack the stability required for certain land-uses. Sinkholes are one of the major indicators of karst terrains. This map provides basic data for land-use planning and decision making.
