Constructed in the 1950s and carrying over 100,000 vehicles per day, the Storrow Drive Interchange is a major commuting route and link to Back Bay.  The interchange includes two reinforced concrete tunnels with steel-framed and reinforced concrete roof sections, classified as bridges.  The DCR was concerned about the weight of existing asphalt paving overburden on tunnel roofs.  Through load testing, long-term monitoring, dead load reduction, and analysis, SGH helped the DCR safely and reliably extend the tunnels’ service life to approximately 10 yrs beyond completion date of the Interim Repairs project.
