FFY20-21 bridge scour monitoring & retofit program

The Alaska Department of Transportation and Public Facilities (ADOT&PF) received a $283,364.68 Formula Grant award from the Federal Highway Administration (FHWA) under the Highway Planning and Construction (CFDA 20.205) federal grant program. The grant supports ADOT&PF's Bridge Scour Monitoring and Retrofit Program, which includes scour monitoring and telemetry at select state bridges, as well as scour and erosion vulnerability assessments, risk management tool development, and countermeasure implementation when vulnerabilities are identified. The program also assists with ice studies to better understand scour risks at bridges during breakup. This is a cooperative project between ADOT&PF and the U.S. Geological Survey that aims to preserve and improve Alaska's bridges through monitoring, assessment, and mitigation of scour-related risks.

Project description

The project supports scour monitoring and telemetry at select state bridges. IT also supports scour and erosion vulnerability assessments, the development of risk management tools, and the implementation of countermeasures and plans of action when bridge scour vulnerabilities have been identified. The project will also support ICE studies to better understand the scour risks at bridges during breakup. This is a cooperative project with the U.S. Geological survey.
