Geofoam Offers Performance and Efficiency, Streamlining Nebraska Traffic
[Editor] Geofoam is a great tool to have in your geotechnical toolbox. It can be used to reduce vertical loads to control settlement or to reduce lateral loads on bridge abutments or other structures. The Pacific Street Bridge Project in Omaha, Nebraska is one project that used geofoam for both of these purposes. In this article, author Nico Sutmoller, Geofoam Specialist with Insulfoam, LLC describes this excellent case study in the application of geofoam to meet the project objectives and provide aditional efficiencies during the construction phase.

Hanging Lake Tunnel (Colorado) repair nearly complete
A stretch of tunnel on Eastbound I-70 in scenic Glenwood Canyon Colorado was closed last March because of a 70-foot long crack in the ceiling.
