Building
and maintaining our highways is expensive.
But here’s a quiz question: on
interstates 95 and 84, what costs a half-million dollars a mile to construct? The answer:
sound barriers.
Why
are we spending that kind of money to enshroud our interstates simply to
protect the peace and quiet of its neighbors?
Didn’t they know that living that close to a highway came with the twin costs
of increased noise and air pollution along with the benefits of proximity to
the highways?
Do
you have sympathy for people who live near airports and then complain about the
jets? Neither do I. But the solution to highway noise is not to
create a walled canyon paid for by others.
Sound
barriers, in my view, are a waste of precious resources. They don’t reduce accidents, improve safety
or do anything about congestion. And
they’re a magnet for graffiti artists.
Three miles of sound barriers on both sides of an interstate would buy
another M8 railcar for Metro-North, taking 100 passengers out of their cars.
Worse
yet, sound barriers really just reflect the sound, not absorb it, sending the
noise further afield. But there are
alternatives:
1) Why not
sound-proof the homes? That has worked
well for neighbors of big airports and would be a lot cheaper than miles of
sound barriers. Plus, insulation against
sound also insulates against energy loss, saving money.
2) Rubberized asphalt.
Let’s reduce the highway noise at its source, literally where the
“rubber meets the road”. Using the
latest in rubberized asphalt some highways have seen a 12 decibel reduction in
noise. And rubberized asphalt, as its
name implies, is made from old tires… about 12 million a year that would
otherwise be junked.
3) Pay for it yourself.
Create special taxing zones in noisy neighborhoods and let those home
owners pay for their sound barriers.
They’re the ones who are benefiting, so shouldn’t they be the ones who
pay? And that investment will easily be
recouped in increased property values.
4) Penalize the noise makers. Let’s crack down on truckers who “Jake
brake”, downshifting noisily to slow their speed instead of using their real brakes. And motorcyclists or those cars with busted
mufflers, they too should be penalized.
5) Go electric.
Electric cars are virtually silent.
And there are electronic ways of using noise cancellation technology
that, on a large scale, can induce quiet at a lower price than building wooden
barricades.
6) Go absorbent.
Where there is room, erect earthen berms alongside the highway which
will absorb the sound. Or if you are
constructing sound barriers, fill them with sound absorbing material, treating
the noise like a sponge, not bouncing it off a hard, flat reflective surface.
Our
interstates, especially I-95, are carrying far more traffic than they were ever
planned to handle. And there is no sign
of it decreasing. In Fairfield County
the rush hour starts about 6 am and runs continuously until 8 pm without a
break.
If
our state’s economy depends on these highways we will have to live with the karmic
cost of a little noise. But if it’s too
much to take, why ask others to pay for its remediation when they are the only
ones benefiting from that spending?
