NCSPA’s Project Spotlight Highway #200
Highway #200, ND
Structural Plate Pipes varying from 96” to 144” were extended along Hwy #200
Standing the test of time these structures have survived nearly 60 years of service and are being extended to accommodate today’s traffic patterns.
Eight existing structural plate pipes were extended at various locations and sites. Fill heights ranging from 2’ to 40’ we found. The exiting structural plate pipes were found to be in great condition so extending them was no problem. The plates ranged in diameter of 96” to 144” and a mixture of round and arch plate.
