A road or bridge contract may not require a party to the contract to provide insurance coverage to another party as an additional insured for claims that arise out of or are caused by the second party’s own negligent, reckless, wanton, or intentional conduct or that of its officers, employees, or agents. Any additional insured coverage required under a road or bridge contract may not be broader than the scope of indemnity provided for in Section 39-9-3 or Section 39-9-4.
