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.

Construction Update for 2014, (Aug. 1, 2014)

In Minnehaha County the Contractor has made up a lot of ground in July and is estimating to be a week behind schedule after the rainy June. The Contractor has 4.5 miles of Shoulder Widening completed from the Minnehaha/Lake County line south and is currently working on full regrade sections from 248th St north 0.5 mile and from 251st St to 250th St. The Contractor is hoping to have these areas completed by the end of the first full week in August. After these areas are complete the Contractor will continue to shoulder widen from 248th St to 250th St. When these areas are completed (estimated the 3rd week in August) the Contractor plans on jumping to the south end of the project at the Hwy 38 junction and start working back to the north with shoulder widening. The contractor is estimating to complete 1 mile per week for shoulder widening operations. Emergency vehicles may be likely able to make it through work areas in this portion of the project with advance notice but it may be faster to avoid them if possible.

The Contractor has also made good progress in July in the Lake County portion of the project. The Contractor has finished 3 miles of full regrade from 244th St to 241st St and has gravel surfacing on the majority of it. The Contractor is currently removing the in-place surfacing from 239th St to 241st St. The surfacing should be removed by the end of the first full week in August and then the Contractor will begin full regrade operations starting at 239th St and heading south. Travel through these areas may be possible depending on the day but it is advised to be avoided unless necessary for safety as there will be heavy machinery in these areas as well as periods when there will be full road closures for pipe installations. The contractor is required to maintain access to people that live in that area so they will be working directly with those folks. The contractor is limited to 2 miles at a time for this type of work and is anticipating finishing 1 mile for every 2 weeks.

The Contractor may begin work on the Franklin Corner (241st St) box culvert towards the end the month. When the Contractor is replacing the box culvert, traffic will not be able to cross the intersection at 241st St. We are planning on putting message boards up a couple weeks in advance of the work to alert local traffic. The Contractor is allowed 21 days to complete the work and have the intersection back open to traffic but the Contractor thinks they can do it closer to 14 days depending on the weather. o Intersection roads will be a priority to keep open during construction and should be open for most of construction. There will be instances when work will need to be done directly at the intersecting roads and will need to be closed for short periods.
