U.S. 385 Roadway Improvement Study

Reason for Study:

The SDDOT has recognized the need to conduct a more in depth study of the roadway's geometrics and determine the feasibility of various roadway improvement options for approximately 15 miles of US 385. The needs for the project are directly related to improving access and safety for current and future traffic levels along the corridor.

Study Limits

The study will examine US 385 for approximately 15 miles (from mileage reference markers 87 to 102) in Pennington and Lawrence Counties. This portion of US 385 extends from north of the Lawrence/Pennington County line to approximately the south-western tip of Sheridan Lake. The Project Area includes land owned by the U.S. Forest Service (USFS) and private landowners.

Public Involvement

The South Dakota Department of Transportation (SDDOT) has a long history of public involvement in the development of transportation plans and projects. The 2005 passage of the Safe, Accountable, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) requires a public involvement process. In accordance with the Department's public participation document, the US 385 Roadway Improvements Study strives to keep the public involved with the study as much as possible. Public meetings for the study will occasionally be scheduled to collect public input, provide information, and answer questions.
