I-93 Fast 14
Ambitious Bridge Replacement
We replaced deteriorated bridge decks that needed replacement along an I-93 corridor that handles nearly 200,000 vehicles per day.
Modular units with two steel girders and a precast concrete deck were fabricated off-site to minimize the on-site work.
Each structure was completed in time to open all lanes of traffic for Monday morning rush hour.

MassDOT’s I-93 Fast 14 was an ambitious design-build bridge replacement project that replaced 14 bridge superstructures along I-93 in Medford, at a record-setting pace – completing in one summer what might typically require four to five years.
The initiative showcased accelerated bridge construction through the innovative use of prefabricated modular units. The superstructure replacements were carried out over ten summer weekends of construction limiting the major work to 55-hour weekends, minimizing disruption to residents and weekday commuters along the heavily traveled highway.
