move forward, we have made certain selections and
they're out there in the environmental review right
now. But this is actually the view of looking up
river of the new proposed structure which is a network
arch.
Now, from project description, Mass. DOT proposes
to replace the current structurally deficient John
Greenleaf Whittier Bridge and improve I-95 from Exit
57, Route 113, through Exit 59, which is I-495, to
Exit 60, which is the 286 exit to Salisbury.
The 1951 built Whittier Bridge mainspan is a
double barrel three-span continuous riveted steel
through-truss. What we found through various studies
and documented also in the environmental documents is
that it is structurally deficient. It's nearing the
end of its economic life, and it was determined that
it could not be rehabilitated or worked into any of
our design options. The highway also upholds an older
design standard. It's geometrically deficient in this
four-mile corridor and it also has some substandard
acceleration, deceleration lanes and some geometry.
As Joe mentioned, it's part of the Mass. DOT
accelerated bridge program where they commit three
billion dollars to spend over an eight-year period.
