6TH ANNUAL CONFERENCE
Asset Management & Operations Harris County Toll Road Authority Presented to the Association for the Management and Operations of Transportation Infrastructure Assets
Harris 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.
Summary of System Assets 120 Centerline miles (682 lane miles)* 191 Bridge structures 10 Mainlane toll plazas 80 Ramp toll plazas 10 Pump stations 6 EZ Tag storefronts 208 Overhead sign structures 6,000+ Small signs 3,257 Roadway + 63 high- mast lights 1,023 acres of right-of-way (ROW) * Coming Spring 2015: Tomball Tollway (6.74 centerline miles)
A 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.
Comprehensive Maintenance Program September 2014 Both Moody’s and Fitch released credit rating reports on U.S. toll roads. “Toll-paying users expect a high rate of service and that the assets will be maintained in a good state of repair.” - Moody’s
Comprehensive Maintenance Program Material Procurement Routine/ Preventative Maintenance Restoration & Replacement (R&R) Three strategies to preserve, maintain and repair the existing system.
Comprehensive Maintenance Program O & M Material Procurement Routine/Preventative Maintenance Restoration & Replacement (R&R) Three strategies to preserve, maintain and repair the existing system.
Material Procurement Supply and store all utilized material Established 140 material Purchase Order (P.O.) Harris County is able to utilize its size to acquire contracts with major material supply vendors: Lowe’s Sherwin Williams Grainger Fastenal HD Supply

EvaluatePlanBudgetScheduleExecuteReport Typical Program Lifecycle
Plan Budget Schedule Execute Report Maintenance Program Lifecycle Evaluate
Evaluate Contract and Material Usage High material costs: Paint: cut paint costs in half From $225k annually Roller vs. spraying Shifted to night schedule Delineators: cut costs in half Type and location Manpower utilization: Raised Pavement Marking (RPM) installation More effective to perform with maintenance contract labor Short-load concrete: Self-batch trailer mixer with maintenance contract labor Fabricate toll booths Cheaper and more efficient to fabricate in-house
Evaluate Process Process changes (Facility / Roadway / Tolling): Closures for preventative maintenance/ to repair booth HVAC system & lighting Closures to replace delineators and maintain REACTs Closures to clean lanes & repair pavement Closures to replace / maintain toll equipment Impacts: Cost of multiple closures by different contractors Possibility of multiple disruptions at one plaza location Uncontrolled working environments Lost toll revenue
Evaluate Process Cooperative Preventative Maintenance: coordinate various contractors’ maintenance closures to occur concurrently
Evaluate Results Lane miles Ave. $23.6 M
Evaluate Condition By 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.
