North Dakota Department of Transportation issued the following announcement on March 25.
THROWBACK THURSDAY!!!
In honor of National Surveyors Week, we want to dedicate this TBT to the men and women who have helped shape ND as surveyors for the NDDOT! From our creation, surveyors have worked to conquer the roughest terrain to lay out the roadways our transportation system relies on today. Thank you to all surveyors!
