Are there any Building Code or near-Building Code (IBC or Life Safety Code) requirements for carbon monoxide alarm ?

What is the NEC Clearance requirement between a roadway and a 161 kv overhead line?  also a 69 kv line? We already have the maximum sag conditions calculated by our local electric company, but I wanted to confirm where the roadway needed to go beneath the calculated sag. Thanks in advance for any input.
