The South Dakota Department of Transportation (SDDOT) hosted a public meeting open house on June 4, 2026, to share the proposed design for the U.S. Highway 85 reconstruction project from the Wyoming state line to U.S. Highway 14A (Cheyenne Crossing) in Lawrence County. The purpose of a public meeting for a proposed project is to provide information and gather public input.

For those who could not attend the June public meeting open house or may desire additional information on the overall proposed project, material is available online at https://dot.sd.gov/ushighway85towy.

Based upon requests from members of the public, the SDDOT has extended the written comment period from the original date of Friday, June 19, 2026, to Friday, Sept. 4, 2026. The date extension will maximize the opportunity for public engagement.

Be cautious, drivers!

Colonel Casey Collins with the South Dakota Highway Patrol reminds drivers to slow down, stay alert, and watch for crews in work zones as you travel across South Dakota.

Construction zones are tight and require a driver’s full attention. Buckle up and put your phone down to help keep both workers and drivers safe.

With temperatures around freezing, snow is falling across portions of the higher elevations of the Black Hills this morning. Over the past week we've had high temperatures, fire weather, severe weather, wind (always wind, it would be strange if we had calm days), and now a little snow. We have fun here! Image courtesy of

Towing a trailer will impact how any vehicle drives. The larger the towed object in comparison to the tow vehicle, the greater the performance impact will be. Thus, knowing what your tow vehicle is capable of towing is just as important as selecting the right trailer.

When buying a hitch, use the tow vehicle manufacturer’s recommendations based on the trailer type and gross vehicle weight rating. Learn more about hitching here: https://www.trailersafetyweek.com/hitching/
