The Problem

Relocating storm sewers and water mains through a busy interchange to improve the traffic flow through the Springfield Interchange. Highways I-95, 395, and 495 all intersect at this location; and traffic congestion in the area required time-efficient relocation of lines for minimal work zone hazards. Relocated existing storm sewers and water mains in the congested area.

The Solution

Using the auger boring method to install 20’ lengths of Permalok® Steel Casing totaling over 2,200 linear feet, R. L Ridgell completed the project on schedule, and at a cost significantly lower than other underground construction methods could have yielded.
