Highlights from FHWA’s 2013 National Bridge Inventory Data:  Of the 18,168 bridges in the state, 2,308 bridges, or 13% 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 3,226 bridges, or 18% 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 North Carolina has supported $1.9 billion in bridge construction spending on 3,384 bridges between 2003 and 2012, according to FHWA data.2  Since 2004, 1,988 new bridges have been constructed in the state and 64 bridges have undergone major reconstruction.  The state estimates that it would cost approximately $29.0 million to fix a total of 7,949 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 493 401,872 10,655,000 28 33,878 647,250 Other principal arterial 1,085 1,221,971 11,601,743 57 138,332 633,500 Minor arterial 716 507,202 5,104,130 68 109,727 419,480 Major collector 2,060 1,109,555 7,695,696 225 221,999 730,575 Minor collector 1,676 528,525 3,001,313 268 63,400 413,063 Local 7,792 1,484,152 5,616,757 1,291 201,443 808,449 Urban Bridges Interstate 665 951,381 27,392,250 24 21,247 993,375 Other freeway 488 654,006 11,869,697 46 63,821 1,368,950 Principal arterial 672 764,289 12,594,945 60 65,013 947,350 Minor arterial 716 572,845 8,390,805 60 44,295 573,750 Collector 422 263,769 3,122,665 49 23,892 250,940 Local 1,383 507,669 6,254,261 132 40,751 458,134 Not classified 0 0 0 0 0 0 Total 18,168 8,967,236 113,299,262 2,308 1,027,798 8,244,816 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 North Carolina

I40 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.
