Dear Transportation Partners:
When MAP-21 expanded the National Highway System, many local roads classified as principal arterials got added into the Enhanced NHS and came under the MAP-21 performance requirements. To comply with the new NHS performance requirement, the state must collect NHS route pavement condition data.
One question some local agencies have been asking is who will be responsible for collecting the pavement condition data. As Caltrans and our transportation partners continue the dialogue on this subject of data collection in HNS, HSIP and many other areas, I would like to share with you that Caltrans has taken some initial steps to collecting pavement data on all NHS routes, including those off the State Highway System to establish a baseline of NHS pavement condition. Caltrans has a 2-year contract to collect pavement data which includes IRI, Rutting, Faulting, and Cracking for the entire enhanced NHS (State and Local NHS roadways). This data is being collected for years 2015 and 2016 and will be reported in FHWA’s Highway Performance Monitoring System (HPMS)
in 2016 and 2017 respectively. Any additional collection of the NHS on the local system after the existing contract is completed is currently under discussion. We will keep you appraised of any new information as it becomes available.
