ABC is realistic option for bridge rehabilitation, resulting in lower user costs and shorter closures

Bala Sivakumar, HNTB director of special bridge projects, authored a new white paper discussing how ABC can lower user costs and reduce closures during bridge rehabilitation projects.

HNTB Corporation released a new white paper, titled Using ABC in rehabilitation projects: A practical application, discussing how accelerated bridge construction can lower user costs and reduce closures during bridge rehabilitation projects.

The white paper examines a case study of Minnesota’s Franklin Avenue Bridge. Precast deck panels, spandrel and pier cap beams, and ornamental railing brought new life to this Hennepin County bridge – a $43 million ABC project completed in just four months.

Written by Bala Sivakumar, PE, HNTB director of special bridge projects and HNTB Fellow, the white paper addresses several aspects of ABC, including:

  • Identifying potential candidate projects
  • Understanding the risk
  • Keeping the closure window short
  • Restoring historical integrity

This white paper is the third from Sivakumar in a series on ABC. Previously, he authored Accelerated bridge construction overview: A solution for reducing user costs and How to implement ABC. All three, along with other ABC-related content, can be found in the newsroom at
