Indicator 31: Bridges in Good Condition
Rationale: Timely maintenance of bridges, a critical part of Minnesota’s infrastructure, is important to the state’s economy and transportation system.
About this indicator: In 2009, 87.4 percent of state Principal Arterial bridges were in Good or Satisfactory structural condition, measured by deck area. This included 53.7 percent in good condition. The remaining 12.6 percent were in fair or poor condition. The target goal set by Mn/DOT is 55 percent in good condition. The 55 percent goal has been met in the past and the state is on target to meet this goal again by 2012.
