HPMS Last Overlay

The Idaho Transportation Department's (ITD) HPMS service is a collection of layers exported from ITDs Roads and Highways Road Network Linear Referencing System (LRS) that are part of the Highway Performance Monitoring System. These layers represent the active records within the LRS. If you need all records (active and retired) or have a need for LRS functionality, please contact ITDs GIS Headquarters team at [e-mail]. These are current "working" records. For the static, published data, please see the records stored at: https://www.fhwa.dot.gov/policyinformation/hpms.cfm
