S.D. 19 Humboldt

Project: P-PH 0019(31)73; PCN 025Z; Minnehaha & Lake Counties

Location: Project begins at the Highway 38 junction in Humboldt and goes north 23.5 miles to the Highway 34 junction near Madison.

Improvement Type: Shoulder Widening, Grading, Asphalt Concrete Surfacing, Lighting and Culvert Replacement

What is Being Built:

For the Lake County portion, the project will be a full reconstruction that will include removing the in-place surface, regrading of the existing roadway, replacing culverts, surfacing of the roadway with gravel, and added lighting at the Highway 34 junction.

For the Minnehaha County portion, the project will consist of 11 miles of shoulder widening and 3 miles of full reconstruction. In the shoulder widening sections the in-place surfacing will not be removed, however, the shoulders will be widened to 8 feet. In the fully reconstructed areas, the in-place surfacing will be removed, the roadway regraded and surfaced with asphalt. Culverts will be replaced in both sections as well as lighting added at the junction of Highway 38.

The reconstruction of the roadway will provide improved site distances, improved drainage, improved roadway conditions, useable shoulders, and an all-around safer road.
