Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (b) The Department upon request from any local authority shall, or upon its own initiative may, conduct an investigation of any bridge or other elevated structure constituting a part of a highway, and if it shall thereupon find that such structure cannot with safety to itself withstand vehicles traveling at the speed otherwise permissible under this Chapter, the Department shall determine and declare the maximum speed of vehicles which such structure can safely withstand, and shall cause or permit suitable signs stating such maximum speed to be erected and maintained before each end of such structure.
    (c) Upon the trial of any person charged with a violation of this Section proof of the determination of the maximum speed by the Department and the existence of such signs is conclusive evidence of the maximum speed which can be maintained with safety to such bridge or structure.
