ND FTFW DESL 11(4) Auto Tour Route

Active

Contract Opportunity

PROJECT DESCRIPTION:

This project is located in Des Lacs National Wildlife Refuge near the city of Kenmare, North Dakota. The project includes aggregate resurfacing, sub excavation, ditch excavation and reconditioning, and culvert replacement on Auto Tour Route 011 Lower Lake Road. Resurfacing the roadway and drainage improvements will provide a more consistent width and improve roadway conditions that have been deteriorating due to weather events and lack of routine maintenance. The proposed improvements will enhance user experience by providing an updated road surface and allow for easier maintenance by the Refuge.

SCOPE OF THE WORK:

This project is to rehabilitate and repair Auto Tour Route 011 Lower Lake Road from approximately milepost 0.0 to mile post 2.0. The project is broken into a base Schedule and three options.

Schedule A: Drainage improvements from 15+75 to 89+50 including spot culvert and/or end section replacement, culvert cleaning, ditch excavation, ditch reconditioning, spot sub excavation, and roadway excavation. Decades of grading the gravel surface has created a berm along the roadway cutting off surface drainage to most of the existing ditches.

Option X: Aggregate surfacing from 15+75 to 60+00.

Option Y: Aggregate surfacing from 60+00 to 89+50

Option Z: Drainage improvements and Aggregate Surfacing from 89+50

to 118+85 including spot culvert cleaning, ditch excavation, and ditch

reconditioning.
