资源简介：
<p>This inventory of Detroit pedestrian bridges and their condition assessments is derived from the Michigan Department of Transportation (MDOT) and includes pedestrian bridges that span State of Michigan roadways only.</p>
<p>Inspections of pedestrian bridges over State of Michigan routes are performed on a risk-based interval by MDOT, not to exceed 24 months. While not governed by the National Bridge Inspection Standards, these inspections are performed to maintain safety of the traveled way and to provide information needed for asset management. Routine Inspections of the entire structure may be supplemented by Special Inspections of Bridge Components that require more frequent monitoring.</p>
<p>Condition ratings for pedestrian bridges are evaluated following the National Bridge Inventory Condition Ratings in a similar manner to vehicle bridges. These ratings are based on a 0-9 scale, where 0 is "Failed condition" and 9, "Excellent condition". Condition ratings are assigned for the deck, superstructure and substructure of each bridge or for each culvert. A culvert is a structure that allows passage under a roadway and has a short span (less than 20 feet).</p>
