The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) HPMS thickness rigid event polyline feature class represents the compacted depth, in inches, of the Portland Cement Concrete (PCC) surface layer in a rigid pavement structure. For rigid pavements, the thickness includes all PCC layers that provide structural strength to the roadway, whether reinforced or unreinforced. <\/SPAN><\/P>

This dataset supports pavement performance modeling, design verification, and condition forecasting. It is reviewed and updated annually as part of ITD\u2019s Highway Performance Monitoring System (HPMS) submittal to the Federal Highway Administration (FHWA). <\/SPAN><\/P>

This layer is an export from Roads and Highways that represents only 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 GIS-Info@itd.idaho.gov. <\/SPAN><\/P>
