For the Record Illinois' 139,930 mile network of state and local roads is the third largest in the nation. Almost 16,500 miles, including 2,169 miles of interstate roads, are under the state's jurisdiction. Of the 26,429 bridges in Illinois, 8,232 are on the state system. The state highway system is very heavily used. The Illinois highway network carries over 108.9 billion vehicle miles of travel annually. Nearly 65 percent of that traffic is carried by the state highway system that constitutes only 12 percent of the total road miles and only 31 percent of all bridges. The state also has the third largest interstate highway system in the country, including three of the nation's ten transcontinental routes that carry the most commercial vehicle traffic. Illinois interstate highways account for about 2 percent of all road miles in Illinois but carry 29 percent of all traffic in the state. This For The Record annual report of accomplishments of the Illinois Department of Transportation's (IDOT) highway improvement program details the improvements made to both the state and local highway systems. The report details the status of each project published in the Proposed Improvements for Illinois Highways FY 2005 and lists projects added to the program and accomplished in addition to those originally published.- This layer displays information regarding the improvements made to both the state and local highway systems.
Annual Program The Fiscal Year 2006 Highway Improvement Program provides $1.725 billion out of the $9.15 billion included in the FY 2006-2011 Proposed Highway Improvement Program.The Fiscal Year 2006 program will be financed by an estimated $935 million of federal funds, $724 million of state funds, and $66 million of local funds. About $1.278 billion is for projects on the state highway system and $447 million is for projects on local street and highway systems.A total of 734 miles of highways and 270 bridges will be constructed or improved through the Fiscal Year 2006 program. Safety and traffic improvements at 146 locations are scheduled.- The Annual Program displays proposed improvements for Illinois Highways .
Multi-Year Program The Illinois Department of Transportation's FY 2010-2015 Proposed Highway Improvement Program totals $10.425 billion and includes a FY 2007 annual program of $1.975 billion. Funding for the 6-year program is made up of $7.085 billion in federal funds, $2.695 billion in state funds and $645 million in local funds. In addition to this program, Governor Rod R. Blagojevich has proposed the Jobs For Illinois Program that will authorize $2.325 billion of Transportation Series A bonds for highway improvements that will bolster job creation throughout the state of Illinois. The new projects associated with this program are listed separately as an Appendix in this document.- This layer displays information regarding the fiscal year 2007-2012 proposed highway improvement program.

Roadway Weather Information ( RWIS Roadway Weather Information System (RWI Roadway Weather Information System (RWIS) is a combination of technologies that collects, models, and transmits weather and road conditions. A variety of sensors collect pavement and atmospheric data that can be transmitted to automated warning systems, traffic operation centers, emergency operation centers, and road maintenance facilities for decision support. The primary goal of the system is accomplished by the use of climatological data to develop road and weather information. When storms or severe weather conditions develop, this information becomes a major tool for roadway-related decision makers and especially those involved with winter maintenance operations. All of these activities work toward making for safer roadway conditions for motorist in Illinois. The weather data shown reflects conditions at specified locations, for the indicated date and time. The data for that site may not be representative of the entire area. In addition, failure of the sensors, or the equipment processing the information, may occur and produce unreliable information. Therefore, this information should not be used as the only factor in determining whether to travel in a particular area. The Illinois Department of Transportation recommends the motorist check other sources, including weather-related sites on the World Wide Web and media weather reports when making travel plans. Illinois Department of Transportation and Surface Systems, Inc. assume no responsibility for the accuracy and /or use of the weather data and are also not responsible for errors resulting from omitted, misstated or erroneous information or assumptions.
