Highways, Roads and Bridges - As introduced, requires the commissioner of transportation to establish rules governing reimbursement of relocation costs to a utility; requires reimbursement of at least $2.5 million for projects with utility relocation costs exceeding $2.5 million; requires the department to approve a utility owner's plan to accomplish the proposed new location of utility facilities in highway rights-of-way if the proposal would effectuate the relocation at the lowest cost to the utility's ratepayers; makes other related revisions. - Amends TCA Title 4 and Title 54.

SB 1792 requires Tennessee's Department of Transportation to reimburse utilities for relocation costs when highway projects necessitate moving infrastructure like power lines, water pipes, or fiber optic networks. It sets a $2.5 million minimum reimbursement for projects exceeding that cost, while allowing higher payments at the commissioner's discretion. The bill clarifies that modern infrastructure - including broadband and fiber optics - is included under "utility" (aligning with current policy), and mandates the commissioner consider factors like ratepayer impact and project scale when approving reimbursements. This codifies existing practice without requiring new state funding, directly affecting utilities and highway construction projects.
