Highlights from FHWA’s 2013 National Bridge Inventory Data:
 Of the 3,099 bridges in the state, 443 bridges, or 14% 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 280 bridges, or 9% of all state bridges, classified as functionally obsolete. This means
the bridge does not meet design standards that are in line with current practice.
 Federal-aid investment in Wyoming has supported $231.6 million in bridge construction
spending on 646 bridges between 2003 and 2012, according to FHWA data.2
 Since 2004, 222 new bridges have been constructed in the state and 23 bridges have undergone
major reconstruction.
 The state estimates that it would cost approximately $215.3 million to fix a total of 1,199
bridges in the state.3

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.

ARTBA analysis of FHWA data, includes all bridge construction related spending on projects approved by FHWA between 2003 and 2012.

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.

Sources: All data is from the 2013 National Bridge Inventory, released by the Federal Highway Administration in March 2014.
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 2013$ 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.
