This project was showcased by the Federal Highway Administrator, Victor Mendez in July 2011, receiving national attention for the innovation it used to get the bridges built so quickly and safely, and for limiting major impacts on road users to off-peak hours.

The 93 Fast 14 Bridge Replacement, hosted by the Federal Highway Administration’s Highways for LIFE program, attracted highway officials from 26 states. These transportation leaders came to learn how to use customer service and safety-driven innovative techniques on their bridge construction projects. ​

The project team fabricated the bridges in segments off site, eliminating years of work in the roadway. The segments MassDOT used are called PBUs or Prefabricated Bridge Units. Each PBU is composed of a concrete deck with two steel beams underneath it. The PBUs were installed by crane and connected with a rapid-setting concrete, replacing at least one bridge each weekend. By replacing the bridges with bridge units that were fabricated off-site, MassDOT eliminated years of work in the roadway.​

The bridges, built roughly sixty years ago, had reached the end of their service lives and were suffering from deterioration. The concrete of the bridge decks was in poor condition. The steel beams under the concrete decks were also in need of repair. MassDOT replaced the steel beams and concrete decks, which together make up the part of the bridge called the superstructure. The bridges’ piers and abutments, which make up the bridges’ substructures, were in good condition. MassDOT repaired the fourteen bridge substructures and revised them to fit the replacement superstructures.
