The first large-scale contracts for the installation of snowplowable markers were awarded in 1984 and 1985. Stimsonite 96 and recessed markers were installed. The objective of this study was to evaluate the performance of the installations. Durability and reflectivity results show that both the recessed markers and Stimsonite 96 markers have performed effectively as snowplowable markers. The recessed markers should continue to be used only on four-lane highways constructed to high geometric standards with the Stimsonite 96 markers installed on the majority of highways.
