IN ADAMS & HETTINGER COUNTIES, NORTH DAKOTA
A major north-south highway in western North Dakota, the rural roadway travels from the South Dakota border and ends at ND23 in McKenzie County. This existing section in Adams and Hettinger Counties was narrow and in need of repair. The 31-mile ND Highway 22 Minor Rehabilitation project began at junction Hwy 12 and went north to New England. The work consisted of sliver grading, mill and overlay, culvert extensions, subcut, and turn lanes. The proposed improvements created a wider subgrade to accommodate a 12’ driving lane and a 2’ shoulder.
During the preliminary engineering design process, the team recommended milling the existing asphalt surfacing and recycling it into the new asphalt surfacing as RAP (Recycled Asphalt Pavement). By using RAP, the project achieved significant cost savings and environmental benefits. In addition, Brosz completed a Traffic Operations Study, and as a result, added three turn lanes to the project.
Brosz completed the environmental documentation (Programmatic CATEX), preliminary survey, right of way, permitting, preliminary design, and final design work on time and under budget.
