Record-Breaking Trenchless Tunneling Success Demonstrates Value on SR-37
Track Title
Design/Construction
Event Description/Abstract
Trenchless tunneling methods were key to the INDOT SR 37 project’s success by providing drainage for new depressed interchanges. Gravity outfall sewers were selected over pump stations, which eliminated long-term O&M costs. This presentation explains how trenchless methods were successful in difficult ground and groundwater conditions. Approximately 1.4 miles of 54-inch-diameter storm sewers were successfully installed using trenchless tunneling methods, including a record breaking 2,304-foot-long curved micro tunnel boring machine (MTBM) run.
