Local governments may finance, install, and operate illumination systems on marked state highways not lighted by TxDOT.

TxDOT cooperates with local governments in the consideration of such illumination systems. TxDOT personnel may assist and advise in the planning and design of such systems when requested by a local government.

Roadway lighting systems installed by local governments on a segment of the state highway system must meet all safety-related requirements under federal and state law and TxDOT functional manuals. These lighting systems should also conform to the National Electrical Code (NEC).

Local governments must obtain written approval from the TxDOT district office for all proposals to install, maintain, and operate on-system lighting. TRF is available to review and offer recommendations when requested by the district. Such installations must be in accordance with the municipal maintenance agreement, if applicable, and in some cases, the local government must obtain a utility permit from the district. A separate agreement is not necessary.
