Notes:

¹Reported Actual = Unit cost submitted by the State for SD NHS bridges replaced in 2012.
² AK, CA, DC, DE,IN, ND, NH, NV, PR, & WY reported no NHS bridge projects in 2012; therefore, the 3-year average of costs for bridge replacements on Federal-aid Highways (FAH) as submitted in 2009, 2010, and 2011 was used.
³National Average = Average of all submitted unit costs for SD NHS bridges replaced in 2012

NHS totals are based on a mix of pre and post-MAP-21 system definitions. States are transitioning to the MAP-21 NHS definition.
Unit costs are described in the memorandum found at: https://www.fhwa.dot.gov/bridge/nbi/121218.cfm

NOTES:

¹Reported Actual = Unit cost submitted by the State for SD non-NHS bridges replaced in 2012.
² DC, HI, NH, NJ, & NV reported no Non-HS bridge projects in 2012; therefore, the 3-year average of costs for bridge replacements on Non-Federal-aid Highways (NFAH) as submitted in 2009, 2010, and 2011 was used.
³National Average = Average of all submitted unit costs for SD non-NHS bridges replaced in 2012

Non-NHS totals are based on a mix of pre and post-MAP-21 system definitions. States are transitioning to the MAP-21 NHS definition.
Unit costs are described in the memorandum found at: https://www.fhwa.dot.gov/bridge/nbi/121218.cfm
