SCL State Route 152 Drainage Improvements and Maintenance Worker Safety Project (EA 04-0Q05U)
Document Type
NOE - Notice of Exemption
Document Description
The project proposes to replace and upsize one cross culvert (PM R16.9) while restoring four drainage systems (PM R16.83, R17.91, R18.0, and R18.24). The purpose of this project is to bring the culvert and infrastructure up to federal standards such as upgrading existing Metal Beam Guardrails (MBGR) with Midwest Guardrail Systems (MGS). This project minimizes future risk for highway maintenance staff. Additionally, the project proposes to repair two side slope slipouts, which have created gullies, along westbound SR 152 (PM 20.5 and PM 20.75). The purpose of this project is to repair storm damage by adding Rock Slope Protection (RSP), installing new drainage systems, and reconstruct the damaged shoulder at PM 20.5 and PM 20.75. This project also minimizes the risk of future issues such as crumbling right-of-way fences and wildlife/livestock escaping to adjacent areas.
