Road
Conditions:
Nearly half – 47 percent- of state-maintained roads
in
New Hampshire
are in substandard condition.
Facts:
- In 2004 (the latest year
for which data is available), 47 percent of
New Hampshire
’s roads were rated in poor or mediocre condition.
- Nationally, a total of 34 percent of roads are rated in poor or mediocre
condition.
- A desirable goal for state
and local organizations that are responsible for
road maintenance is to have 75 percent of major
roads in good condition. Only 36 percent of
New Hampshire
’s state-maintained roads are in good condition.
Bridge
Conditions:
Nearly
one-third – 32 percent – of bridges in
New Hampshire
are in
substandard condition. This includes all bridges that
are 20 feet in length or more and are maintained by
state, local and federal agencies.
Facts:
- Fourteen
percent of
New Hampshire
’s bridges were structurally deficient in 2005
(the latest year for which data is available). A
bridge is structurally deficient if there is
significant deterioration of the bridge deck,
supports or other major components. Structurally
deficient bridges are often posted for lower weight
or closed to traffic, restricting or redirecting
commercial trucks and emergency services vehicles.
- Eighteen
percent of
New Hampshire
’s bridges were functionally obsolete in 2005.
Bridges that are functionally obsolete no longer
meet current highway design standards, often because
of narrow lanes, inadequate underclearances or poor
alignment.
- Nationally,
13 percent of bridges are structurally deficient and
14 percent are functionally obsolete.
- The
following is a list of the ten most heavily traveled
bridges in
New Hampshire
that are also structurally deficient. An expanded,
more complete list is included in the body of this
study.
