The document summarizes bridge data from Hawaii's 2014 National Bridge Inventory. It finds that 5% of Hawaii's 1,137 bridges are structurally deficient, while 37% are functionally obsolete. From 2004 to 2014, 25 new bridges were built and 11 underwent major reconstruction in Hawaii. The state estimates it would cost $1.2 billion to repair 1,112 bridges. The top 10 most traveled structurally deficient bridges and types of proposed bridge work are also outlined.

Highlights from FHWA’s 2014 National Bridge Inventory Data:
 Of the 1,137 bridges in the state, 61 bridges, or 5% are classified as structurally deficient. This
means one or more of the key bridge elements, such as the deck, superstructure or
substructure, is considered to be in “poor” or worse condition.1
 There are 422 bridges, or 37% of all state bridges, classified as functionally obsolete. This means
the bridge does not meet design standards that are in line with current practice.
 State and local contract awards for bridge construction totaled $161.43 million over the past
five years, 12 percent of highway and bridge contract awards, compared to a national average of
29 percent.
 Since 2004, 25 new bridges have been constructed in the state and 11 bridges have undergone
major reconstruction.
 The state estimates that it would cost approximately $1.2 billion to fix a total of 1,112 bridges in
the state.2

According to the Federal Highway Administration (FHWA), a bridge is classified as structurally deficient if the condition rating for the deck,
superstructure, substructure or culvert and retaining walls is rated 4 or below or if the bridge receives an appraisal rating of 2 or less for
structural condition or waterway adequacy. During inspections, the condition of a variety of bridge elements are rated on a scale of 0 (failed
condition) to 9 (excellent condition). A rating of 4 is considered “poor” condition and the individual element displays signs of advanced section
loss, deterioration, spalling or scour.

This data is provided by bridge owners as part of the FHWA data and is required for any bridge eligible for the Highway Bridge Replacement
and Rehabilitation Program. However, for some states this amount is very low and likely not an accurate reflection of current costs.

Note that specific conditions on bridge may have changed as a result of recent work. Cost estimates of bridge work provided as
part of the data and have been adjusted to 2014$ for inflation and estimated project costs. Contract awards data is for state
and local government awards and comes from McGraw Hill. Note that additional bridge investment may be a part of other
contract awards if a smaller bridge project is included with a highway project, and that would not be accounted for in the total
in this profile.
