Italian contractor Trevi has released images of its work building the foundations for the new North Washington St. Bridge in Boston, Massachusetts that crosses the city’s Inner Harbour.
It will replace the more-than 100-year-old original, which has been struggling and needs to retire.
Trevi was picked selected as subcontractor on the project, which is owned by MassDOT Highway Division. General contractor is general contractor, J.F. White Contracting.

The foundation works consist in the execution of 40 drilled shafts, six feet in diameter, and rock sockets with 5.5 feet diameters, with lengths ranging from 63 to 95 feet.
The drilled shafts are excavated from temporary cofferdams installed at the location of the bridge’s five new piers.
"After more than 100 years of service, we are replacing the North Washington Street Bridge with a new bridge for the 21st Century," says MassDOT, adding that the bridge will be "a complete street over water that works for everyone: people driving, riding the bus, biking, walking, sightseeing, boating, and living nearby."

The bridge is integral to daily life in Boston, but it has been "struggling to fulfil those purposes", said MassDOT.
The centre bay has been closed since 2003, and since autumn 2017, ongoing emergency repairs have further restricted lanes.
"It is due for a well-deserved retirement," said MassDOT.
