Case Study Details

The Jack Schmiedel Memorial Bridge, located at State Highway 74 and 150th Street in Oklahoma City, received a targeted drainage system upgrade led by the Oklahoma Department of Transportation (ODOT).Like many integral bridge abutments, the Jack Schmiedel Memorial Bridge was at risk for hydrostatic pressure buildup, soil saturation, and erosion—conditions that can compromise the stability of reinforced concrete structures over time. ODOT recognized that poor water drainage behind reinforced concrete barriers would increase maintenance costs and structural risk.

Products Used

• 6 units of JET Filter – JF4SS: 4″ Diameter Open End Maintainable Weep Hole Filter, featuring ASTM 316/316L Stainless Steel Housing and Mirafi® Filter-Weave FW 300 Geotextile Filter Media.

Solutions

ODOT recognized that poor water drainage behind reinforced concrete barriers would increase maintenance costs and structural risk. To mitigate these concerns, the agency initiated a drainage improvement project using high-quality, corrosion-resistant weep hole assemblies. JET Filter System supplied and supported the installation of six maintainable weep hole drains (JF4SS) as part of the integral bridge abutment drainage upgrade. The ODOT in-house engineering and construction team managed the full project, ensuring quality control and adherence to state infrastructure standards.
