On this particular bridge replacement, Guthrie County was replacing a 22’ long x 16’ wide timber bridge that had no record of installation date. The Guthrie county engineer considered three replacement options based on the size of the drainage area and required hydraulics at the site. Option 1 was a Single 6’ x 7’ reinforced concrete box; Option 2 was a single 84” corrugated metal pipe; and Option 3 was a twin run of 60” corrugated metal pipes. When the cost analysis was completed, the single run of 84” CMP was the clear winner.

In March of 2016, Crittenden Co., KY decided to replace a structural plate bridge built in approximately 1945. This bridge is located in the most northern part of the county on Hurricane Church Road, approximately five miles south of the "Cave in Rock" ferry, which still crosses over the Ohio River many times each date. This bridge has allowed safe passage over a tributary of Caney Fork Creek for many years providing access to the historic Old Hurricane Methodist Church and Cemetery where you can find some of the oldest graves in Crittenden County - some dating back before the Civil War.
Mar-Jac Poultry in Spruce Pine, AL needed an unconventional storm sewer system for it’s new $35 million feedmill. Because of the nearly 100’ canyon walls at the location, the storm sewer system needed to account for an anticipated height of cover in excess of 80’ – a height that exceeded many allowable limits on all design charts for the typical concrete, corrugated metal and precast box culverts.
Original plans for a new Chrysler Dealership in Pineville, NC included a modular reinforced concrete storm water detention system – but at a hefty price.

A 6” minimum benign envelope around the pipe using pea gravel was incorporated to abate the poor resistivity readings that periodically occurred at this site.
This job consisted of 6300 LF of CSP and 3200 LF of spiral rib pipe including several large tees, elbows, & misc. fittings.
A run of CSP totaling 5700 linear feet of 72” diameter (81” x 59”) arched storm drain was designed to accommodate a section of the project where soil conditions were not conducive to open channel ditch construction.
Access points were placed every 400’ for ventilation and cleanout. 48’ pipe sections were supplied to accommodate contractors request to reduce freight, joint connections and equipment limitations.
Aluminized Type ll steel was selected to provide an extended service life.
With over 14,680 LF (sections varying from 4,594 LF of 15-in diameter to 5,162 LF in 42-in diameter and 263 LF in 60-in), the mobile mill offered the perfect flexibility for the variety of pipe diameters needed to complete the job.
Using a low profile box culverts kept the project on budget, on schedule and provided a sustainable option.
These pipes are set vertically into a concrete base and sealed with silicone or a spray sealant. They are then covered with a solid vented lid and plumbed for use.
Corrugated steel water tanks are designed to be an aesthetically pleasing and cost effective solution used for rain water harvesting.
As the aging infrastructure impact all transportation types, corrugated steel pipe was a solution to the rehabilitation of this old railroad timber structure.
Keeping the transportation running is the most important part of the rehab project. This crossing was not shut down any though the entire installation process.
The deteriorating culvert had experienced major encroachment along the toe of the slope after a major rain event and catastrophic washouts.
Standing the test of time these structures have survived nearly 60 years of service and are being extended to accommodate today’s traffic patterns.
The North Dakota Department of Transportation had a problem with joint separation and spalling concrete in a 10’ x 8’ cast-in-place Reinforced concrete box culvert built in 1934, and extended in 1960.
Fulfilling the order for this project created challenges in that the diameter was barely able to fit through our fabricating plant door, the pipes were so heavy that up to 3 forklifts were used to lift/transport the product.
Constructed in 2011, this is the longest single span box culvert of any material in North America. This was also the first large span steel buried bridge to take advantage of its flexible nature in the foundation design.
This half-round CSP structure, with its own footing plates, was designed by Pacific Corrugated Pipe Co. for bridging small streams on a temporary basis.
