Bypass, traffic control, cleaning, and lining. What doesn’t Allied do! Longview was a job that had many twists and turns. Literally! Allied lined a 36-inch pipe with a 45-degree turn. Not only were we lining angle changes but we completed our own bypass and traffic control. In a high-traffic area, our 12 inches lay flat bypass crossed over four inspections. We were able to build ramps to allow safety for the area and our equipment.
