(605 ILCS 115/15) (from Ch. 137, par. 15)

Sec. 15. Whenever the county board of any county shall deem it for the public interest that any toll bridge in such county should be made a free bridge, it may take and condemn the same for that purpose, in the manner then provided by law for the exercise of the right of eminent domain. If the bridge is situated in two counties, such right may be exercised, and the proceedings had in behalf of such counties, jointly.
