Highlights from FHWA’s 2014 National Bridge Inventory Data:  Of the 5,872 bridges in the state, 1,174 bridges, or 20% 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 238 bridges, or 4% 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 $247.57 million over the past five years, 13 percent of highway and bridge contract awards, compared to a national average of 29 percent.  Since 2004, 450 new bridges have been constructed in the state and 35 bridges have undergone major reconstruction.  The state estimates that it would cost approximately $700.7 million to fix a total of 2,405 bridges in the state.2 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 338 192,357 1,646,373 3 2,479 14,464 Other principal arterial 451 223,033 893,246 17 15,907 33,885 Minor arterial 521 207,233 592,543 18 10,483 25,029 Major collector 1,158 313,994 412,027 190 48,548 53,843 Minor collector 161 44,784 22,889 33 4,733 5,239 Local 2,843 373,794 212,516 882 90,152 59,055 Urban Bridges Interstate 117 104,809 1,447,664 3 2,772 49,415 Other freeway 6 10,827 61,489 0 0 0 Principal arterial 72 84,587 813,833 1 1,645 22,694 Minor arterial 88 69,032 608,935 6 5,187 35,755 Collector 51 27,650 200,046 10 7,170 49,285 Rural 66 13,713 62,984 11 2,160 2,739 Total 5,872 1,665,814 6,974,545 1,174 191,235 351,403 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 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 South Dakota

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.
