Just recently the Harris County Commissioners Court expanded a $175,000 contract with local engineering consultant Walter P. Moore to develop a preventive maintenance plan for ASR on the tollway system’s 30 bridges and 107 miles of concrete.
At a meeting back on Aug. 11, commissioners sought bids for a $504,000 project to repair cracked concrete on connector bridges on the Westpark and Sam Houston tollways, and a $1.2 million contract is already in place for a bridge over the Houston Tollway at U.S. 290 following repairs completed in January 2008 to an older bridge connecting I-45 south to the Hardy Toll Road that cost over $468,000.
The ASR problem is not limited to the Houston area either. The Texas Department of Transportation estimates that about 1,000 bridges are infected with the problem.
