Highlights from FHWA’s 2013 National Bridge Inventory Data:  Of the 7,902 bridges in the state, 372 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 1,694 bridges, or 21% 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 Washington has supported $3.7 billion in bridge construction spending on 1,512 bridges between 2003 and 2012, according to FHWA data.2  Since 2004, 703 new bridges have been constructed in the state and 138 bridges have undergone major reconstruction.  The state estimates that it would cost approximately $55.6 billion to fix a total of 5,741 bridges in the state.3 Bridge Inventory: All Bridges Structurally deficient Bridges Type of Bridge Total Number Area (sq. meters) Daily Crossings Total Number Area (sq. meters) Daily Crossings Rural Bridges Interstate 292 343,490 4,540,846 37 51,050 504,928 Other principal arterial 561 501,056 3,292,232 29 48,825 182,723 Minor arterial 344 253,270 1,502,681 17 12,955 80,799 Major collector 1,283 539,089 2,204,273 77 35,081 151,405 Minor collector 750 197,563 474,535 22 6,248 13,719 Local 2,082 397,324 469,619 78 11,635 31,065 Urban Bridges Interstate 651 1,757,064 26,838,816 13 119,071 261,684 Other freeway 474 1,271,076 12,849,175 13 173,470 453,110 Principal arterial 445 815,418 8,163,360 36 90,866 655,019 Minor arterial 511 591,154 5,337,821 30 62,444 328,003 Collector 224 167,855 1,145,019 6 3,905 31,584 Local 285 132,659 589,062 14 2,843 18,220 Not classified 0 0 0 0 0 0 Total 7,902 6,967,018 67,407,439 372 618,394 2,712,259 1 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. 2 ARTBA analysis of FHWA data, includes all bridge construction related spending on projects approved by FHWA between 2003 and 2012. 3 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. State Bridge Profile Washington

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.
