US14-US14 Bypass Corridor Study – Public Meeting #3

Virtual Public Information Meeting and Open House

Welcome to our US14-US14 Bypass Corridor Study virtual engagement! The South Dakota Department of Transportation (SDDOT) in conjunction with the City of Brookings and City of Volga are leading a study to develop a long range plan for the US14 and US14 Bypass corridors. Thank you for your participation in our online engagement.

The range of transportation improvement scenarios presented here are ready for public and stakeholder feedback. These scenarios group refined concepts presented at the previous public meeting and represent potential future projects to address long-term transportation needs. We appreciate your input.

Plan Overview

The Bicycle and Pedestrian Plan presents a long-range plan for bicycle and pedestrian facilities along the urban and developing areas of the US14-US14 Bypass corridor. This plan will serve as a guide for incorporating shared-use path facilities in future projects and promoting a continuous and connected network.

• In Volga: continuous shared-use path on the north side of US14 with future crossing locations.

• Volga to Brookings: route options to provide a shared-use path between Volga and Brookings.

• US14 Bypass: continuous shared-use path on the south side of US14 Bypass with potential connections to existing and planned City of Brookings and SDSU bicycle and pedestrian facilities.

Plan Overview

The ITS Plan presents potential ITS technologies and deployment locations for consideration as part of improvements to the US14-US14 Bypass corridor. This plan can be used as a guide to implement these technologies as part of future corridor projects and/or SDDOT statewide ITS programs.

Plan Overview

The Blowing Snow Plan identifies potential locations for snow fence at problematic blowing snow areas identified by the study team, SDDOT maintenance staff, the public, and study stakeholders along the US14-US14 Bypass corridor. This plan will serve as a guide for implementation of snow fences as well as incorporation of blowing snow measures into design as part of future corridor projects.
