1. 146th St. West - Phase 2

   The expansion of 146th Street will continue from west of Springmill Road to the Boone County Line. The road will be reconstructed to a 5-lane section with center median.

2. 276th St. Reconstruction

   The purpose of the project is to rehabilitate 276th St. east of US 31, from US 31 to Gwinn Rd., a distance of 4.5 miles. The scope is to widen the narrow lanes and add 3' paved shoulders. Side drainage ditches will also be improved.

3. Bridge 36 Maintenance

   Bridge Replacement. The existing timber structure will be replaced with a spread box beam superstructure on spill through end bents. The profile will be raised slightly to accommodate the deeper superstructure. The bridge will be lengthened to lower the backwater elevation at this location. The bridge will be designed to accommodate 2-12’ lanes with 4’ shoulders on both sides. The existing horizontal curves will be designed to impact as little right-of-way as possible, but to also improve safely along these curves.

4. Bridge 117 Rehabilitation

   Project is currently under consideration for either Bridge Rehabilitation or Bridge Replacement.

5. Bridge 124 Replacement

   Bridge Replacement. The existing timber structure will be replaced with a spread box beam superstructure on spill through end bents. The profile will be raised slightly to accommodate the deeper superstructure. The bridge will be lengthened to lower the backwater elevation at this location. The bridge will be designed to accommodate 2-12’ lanes with 4’ shoulders on both sides. The existing horizontal curves will be designed to impact as little right-of-way as possible, but to also improve safely along these curves.

7. Structure #23034 - Cyntheanne over Keiser Drain

   The proposed design will widen the structure roadway width from existing and meet current safety standards. The new structure will be able to accommodate Q100 flood event with additional 2 feet of free board for unexpected events.

8. Structure #33008 - 241st St. over Sugar Run

   The Proposed design will widen the structure roadway width, realign ditch, and meet current safety standards. Structures will be able to accommodate a Q100 flood event.

9. Structure #33065 - Deer Walk Dr. over Webb Ditch

   The proposed design will keep the same roadway width and length. Structure will be able to accommodate a Q100 flood event.
