George Washington Memorial Parkway

In 2014, a large sink hole opened at the Windy Run bridge along the George Washington Memorial Parkway. The erosion control system had failed and water was draining through the fabric directly out the weep holes in the bridge abutment below. JET Filter System’s 4” dia. maintainable weep hole filters were the perfect solution.

Natchez Trace Parkway Case Study

Constructed in the 1930’s – 1940’s, the Natchez Trail Parkway winds its way from Natchez, Mississippi to Fairview, Tennessee. The scenic roadway contains ~400 overpasses & bridges.  Maintenance costs have increased dramatically as many of the structures show signs of distress. One of the biggest issues was soil erosion in and around bridge abutments due to failed drainage systems.

coopersville case study

Michigan DOT I-96 Culvert

Near Coopersville, MI, I-96 crosses a large drainage culvert that extends more than 100’ under the East & West bound lanes as well as the median. Michigan DOT maintenance and bridge inspection forces found that significant amounts of supporting soils were leaching through existing weep holes during large rain events and suspected voids may be present behind the culvert walls.
