The width of a bridge is compared to standards for the amount of traffic it carries. Considers approach roadway geometrySufficiency Rating: Sufficiency Rating Sufficiency rating is a formula used to determine eligibility for funding based on: - 55% structural condition - 30% bridge geometry - 15% traffic considerationsBridge Funding: Bridge Funding Federal 20’ Sufficiency rating <80 to rehabilitate <50 to replace Functionally obsolete or structurally deficient State 10’ Sufficiency rating <80 Functionally obsolete or structurally deficientBridge Inspection: Bridge Inspection Certified inspectors Structures over 10’ Inspection schedule Annual: Fracture critical, poor condition 2 years: Routine, good condition 5 years: In depth fracture critical, scourDakota County Bridges: Dakota County Bridges 83 bridges on the County system No bridges on the County system are structurally deficient Two bridges recently became functionally obsolete due to traffic counts Average sufficiency rating of 92.4 11 County bridges replaced since 2000Township Bridges: Township Bridges Minnesota Statute 156.03 requires that the County Engineer inspect all County and Township bridges 56 bridges on the Township system Two structurally deficient bridges Two functionally obsolete bridges 11 township bridges replaced since 2000State Wide Bridge Needs: State Wide Bridge Needs Local Bridges (14,695) 1,831 functionally obsolete or structurally deficient $1 Billion Mn/DOT Bridges (4,610) 177 fracture critical, functionally obsolete or structurally deficient $1.46 Billion Hastings TH 61 Lafayette TH 52 Many bridges built between 1950 and 1970 You do not have the permission to view this presentation.
