spiral rib ALT2 storm drainage system

Paseo Del Norte – 2015 DOT Project of the Year

By: Contech Engineered Solutions

In August 2013, the New Mexico Department of Transportation (NMDOT – District 3), the City of Albuquerque, the Federal Highway Administration (FHWA) and Bernalillo County announced the selection of the design-build team for the Paseo Del Norte / I-25 Interchange Reconstruction project.

The goal of the project focused predominately on improving traffic flow for the I-25 corridor on the north side of the Albuquerque, New Mexico Metropolitan area.

As part of the project, Contech Engineered Solutions worked closely with the design-build team to design and manufacture a storm drainage system beneath the new interchange.

The system included polymeric corrugated metal pipe (CMP) and one of the most hydraulically efficient storm sewer systems available – spiral rib ALT2 CMP.

Diameters ranged from 24-in to 108-in and gages ranged from 16 to 10 gage. In total, over 12,000 ft. of CMP was installed as a speedy and cost effective solution.
