Continuous lighting provides lighting along a stretch of freeway or expressway to enhance the overall nighttime visibility and safety of traffic.

There are two kinds of standard agreements for continuous lighting systems - the "100 Percent Agreement" and the "50-50 Agreement." Which agreement is used depends on whether TxDOT bears the entire cost of the system or shares the expense with a local government.

The 100 percent agreement provides that TxDOT assumes the total cost of design and installation of the continuous lighting system, and that the local government assumes all cost of the subsequent operation and maintenance.

The 50-50 agreement provides that TxDOT and the local government share equally the cost of the installation, operation, and maintenance of the continuous lighting system
