CONTECH \| ENGINEERED SOLUTIONS       February 2025         I-35 Overpass Roadway Improvement Project Des Moines, Iowa   Slotted Drain Improves Surface Runoff   During a project to add a bridge while widening Interstate 35 from two to three lanes in each direction for approximately eight miles, the Iowa Department of Transportation also needed to address runoff concerns. After careful consideration, a Contech Slotted Drain™ system was selected as the best solution for its ability to play a pivotal role in ensuring the safety and functionality of the newly improved areas of the roadway.   Read More         Building Bridges   Colorado Department of Transportation - Region 2 Southeastern, Colorado   Eight Aluminum Box Culverts Replace Deteriorating/Under Sized Structures   When 17 bridge structures in southeastern Colorado needed to be replaced, the Colorado Department of Transportation determined that Aluminum Box Culverts provided the best solutions for eight of them.    Read More         Stormwatch   45th East Roadway Widening - Phase 2 Idaho Falls, Idaho   CMP Detention Detains Stormwater   The 45th East Roadway Widening project involved expanding Crowley Road into a four-lane roadway. Due to the absence of an existing storm drain system, engineers used corrugated metal pipe to store and infiltrate stormwater runoff within the road's shoulder, effectively managing stormwater without traditional drainage infrastructure.   Read More           Pipe Solutions Blog       Estimating the Cost of a Reline Project: What to Expect       We are often asked, “How much does a reline project cost?” While this is a straightforward question, the answer depends on multiple factors. Before attempting to provide a cost estimate, it’s important to consider the broader perspective—particularly in comparison to traditional open-cut replacement. In most cases, segmental sliplining is the most cost-effective reline method unless unique site conditions—such as low traffic volumes, short detour distances, or shallow cover with no utilities—make open-cut replacement a viable alternative. However, generalized cost estimates without accounting for site-specific design and construction constraints can be misleading.     Read More           Stormwater Blog       Blending Beauty and Efficiency: Aesthetic Options of High-Rate Bioretention Systems       Civil engineers understand the delicate balance between form and function. High-rate bioretention systems, known for their efficiency in managing stormwater, offer an often overlooked benefit: aesthetics. Integrating visually appealing bioretention systems into urban landscapes can enhance community engagement, foster sustainability, and improve the overall perception of civil infrastructure. Traditional stormwater solutions often prioritize performance over appearance. However, high-rate bioretention systems, when thoughtfully designed, can seamlessly blend utility with beauty.       Read More         NEWSWORTHY WEBINAR - EARN A PDH CREDIT   Protecting Our Water Resources: Practical Insights for the Municipal Water Industry   Thursday \| March 20 \| 2 PM EST   Contech Engineered Solutions and U.S. Pipe are teaming up to deliver an educational webinar designed to address the challenges and opportunities in municipal water and wastewater infrastructure.
