Recycled plastic has been used in this project in several ways. The guardrail offset blocks - the blocks that are inserted between the steel guardrails and the support posts behind them - are made from recycled plastic. Offsetting the rail from the support posts with a plastic block stabilizes the guardrail and also helps minimize the damage inflicted to cars that may bump against it. In addition to offset blocks, temporary slope drainage pipes made from recycled plastic were used during excavation of the highway embankments. Recycled plastic delineators - the flexible guideposts that help direct traffic - were also installed
