CONTECH \| ENGINEERED SOLUTIONS       September 2025         State Highway 21 Wildlife Overpass Boise, Idaho   BEBO Provides Safe Crossing for Wildlife   As part of a plan to improve motorist safety and reduce vehicle-wildlife accidents by 80% along State Highway 21, Idaho state officials determined the best solution was to install a BEBO® Bridge Concrete Arch System. The precast concrete structure provides safe passage for wildlife above and vehicular traffic below.     Read More         Stormwatch   Louisville International Airport Shuttle Lot Expansion Louisville, Kentucky   CMP and Cascade Manage Stormwater   The expansion of the Express Shuttle Parking Lot at Louisville Muhammad Ali International Airport resulted in a significant increase in impervious surfaces, necessitating a robust stormwater management solution. With no space available for an above-ground system, an underground corrugated metal pipe detention system was installed on the site.   Read More         Conveyance   Route 73 Seal Harbor AOP Improvements Knox County, Maine   HEL-COR Restores Fish Passage   During ongoing efforts to restore fish passage, MaineDOT determined that Seal Harbor Bridge, an existing culvert running under Route 73, no longer met the necessary design requirements for an optimal Aquatic Organism Passage. The structure was replaced with a HEL-COR® polymer-coated corrugated metal pipe.   Read More           Pipe Solutions Blog       Corrugated Aluminum Pipe: Proven Performance in Salt and Brackish Environments       When it comes to drainage solutions in aggressive environments, material selection makes all the difference. Traditional galvanized corrugated metal pipe often struggles to withstand the corrosive effects of saltwater, brackish water, and hypersaline soils. That’s where Corrugated Aluminum Alloy Pipe (CAP) stands apart.     Read More           Stormwater Blog       Flexibility by Design: Custom Corrugated Metal Pipe Layouts for Challenging Sites       Stormwater design isn't always straightforward. Between utility conflicts, easement restrictions, odd property lines, and topography, most sites require more than a one-size-fits-all solution. That’s where the flexibility of corrugated metal pipe comes in.         Read More         NEWSWORTHY - EARN A PDH CREDIT   Mastering the Design of CMP Detention and Infiltration Systems     This article outlines key considerations for selecting and designing CMP systems, providing practical guidance informed by field experience, engineering principles and best practices in constructability.
