About the project
The Iowa 92 over Little Silver Creek bridge replacement project incorporates numerous innovative technologies contributing toward advancements in project safety, construction schedule, construction impact, project quality, user satisfaction, and service life.
This bridge replacement project represents Iowa DOT’s second-generation design efforts for accelerated bridge construction (ABC) using prefabricated bridge elements and systems (PBES). Generally based on the U.S. 6 over Keg Creek modular decked beam concept, www.iowadot.gov/us6kegcreek/, the Iowa 92 over Little Silver Creek project builds upon the experience gained and lessons learned from the department’s 2011 Strategic Highway Research Program SHRP2 Project R04, demonstration project.
The Iowa 92 over Little Silver Creek bridge replacement project has been recognized by the Federal Highway Administration for accelerated implementation and adoption of innovative technology in highway transportation. This project is the recipient of an incentive funding grant of $1 million as a part of FHWA’s Accelerated Innovation Deployment (AID) program.
