3Harris County Toll Road Authority The Toll Road Authority was created by Harris County Commissioners Court in 1983 after Harris County voters approved a referendum to release $900 million in bonds to construct toll roads in the rapidly growing Greater Houston Metropolitan area. Harris County Toll Road Authority provides a transportation option to help address regional growth that is independent of State planning or funding, which cannot support the mobility needs of that region. The toll rate is the funding mechanism used by the HCTRA to construct, operate and maintain the needed infrastructure.

5A major challenge for a transportation agency is solving how to maintain aging infrastructure to accommodate growing or densely populated regions. The condition of infrastructure will influence the commerce, growth, and standard of living in a region.
6Comprehensive Maintenance Program “Toll-paying users expect a high rate of service and that the assets will be maintained in a good state of repair.”- Moody’sSeptember 2014Both Moody’s and Fitch released credit rating reports on U.S. toll roads.

20Evaluate ConditionBy satisfying the senior lien revenue bond indenture, the Annual System Inspection Report is the basis of the yearly Restoration and Replacement Maintenance Projects (R&R Projects) budget forecast.The Annual System Inspection Report identifies system-wide deficiencies within the existing facility and roadway infrastructure, and outlines a two to five year implementation plan.HCTRA Maintenance then determines whether to correct these deficiencies by either incorporating the repair into the Routine / Preventative Maintenance Program (O&M), or acquiring additional engineering consulting support to develop future Restoration and Replacement Maintenance Projects on an annual basis.
