Interstate maintenance funds can also be used to build high occupancy vehicle (HOV) lanes or auxiliary lanes on interstate highways; however, funds cannot be used to add lanes for single occupancy vehicles.
This category also addresses the replacement and refurbishing of signs and their appurtenances, raised reflective pavement markers and thermoplastic striping on interstate highways.
All projects must be developed in accordance with applicable federal and state environmental requirements. All projects must be designed, constructed, operated, and maintained in accordance with state laws, regulations, directives; and safety, design, and construction standards as required by TEA-21.

Allocation to Districts
Allocations for the Interstate Rehabilitation Programs are approved by the commission, with the districts receiving allocations based on the following formula:
- 45% - summation of flexible and rigid equivalent single-axle loads per interstate highway section multiplied times the interstate highway section length
- 10% - interstate lane miles (main lanes only)
- 45% - interstate lane miles (main lanes only) having substandard distress scores, based on Pavement Management Information System (PMIS) Distress Score less than 40.
The Interstate Rehabilitation Programs are managed as bank balance programs with eligible projects developed by the districts on an as-needed basis within their allocations. Interstate Rehabilitation Programs are usually one-year programs with the program funds available for use within four years.Anchor: #i1021463
As allowed by the provisions of the TEA-21, up to 50 percent of the apportioned money in this category may be transferred to the NHS.
