DVRPC-GISDVRPC, in partnership with PennDOT District 6, has developed the web-based IDRuM application that organizes all existing PennDOT Emergency Detour Routes within the DVRPC region. IDRuM compiles the PDF detour maps into a simple "point-and-click" online application which allows the PDF detour maps to be downloaded to be viewed, saved, and/or printed. All detour routes are PennDOT District 6 approved for both passenger vehicles and heavy trucks. The detour route PDFs can be used by first responders, planners, and/or anyone who is in need of DOT approved detour route plans.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/329c7c087a524431a0fbec135bb73152_0engDelaware Valley Regional Planning Commission (DVRPC)PublicDetour Routes [Pennsylvania]Web servicesPennsylvaniaLast Modified: 2025-12-18
