Ind. Code § 8-1-23-2
If any person shall desire to temporarily obstruct a county highway which obstruction may result in damage to the highway or temporary blocking of traffic over the highway, such person shall first obtain permission, in writing, which writing shall be entered of record, from the board of county commissioners of the county wherein such highway or highways is located, or the boards of county commissioners of adjoining counties acting together, if the obstructed or interrupted part thereof is located upon a county line or extends from one county to another.
Before such permission may be granted by any board of county commissioners, such person shall first file with each board of county commissioners from which permission is requested, a surety bond, in a sum to be fixed by and to the approval of such board of county commissioners, payable to the county, conditioned either upon the payment of any damages which such county or road may sustain or upon the proper restoration of such highway, as such county commissioners may direct.
