Roundabout Timeline - Hwy 77/92/109

On March 20, 2024 City of Wahoo staff attended the pre-construction meeting with the NE Department of Transportation for the US-77, Wahoo Intersection - Roundabout project. At that meeting the following details/timeline were shared:

Contractor:  Graham Construction, Inc.


Below is an explanation of the phases of this project. Please keep in mind that the timing of the phases is based on engineers' best estimates and can be significantly impacted by weather delays, unforeseen construction adjustments, and contractor issues. During this project east and westbound traffic will not be detoured.  However, slowing down as you pass through the construction areas is essential to the safety of crews. The difference in your arrival time at your destination between 60 mph and 30 mph is less than 1 minute.  Slow down and keep people alive.

Pre-construction electrical relocation work is currently being done by a contractor and is expected to be completed mid-May.

COMPLETED - Phases 1 and 2 of the construction project will not impact access of any traffic. The working being done is prep work for Phase 3 when access to Old Hwy 77 (south of the intersection) will be detoured.  It is estimated Phases 1 and 2 will be completed late May/early June. Please watch for workers and use caution and slow your speed as you pass through this intersection.

START DATE 5/17/2024 - Phase 3 (Shown as PHASE 1 on the NDOT info sheet) of the project is when detours for this project will begin. This phase will close off any access to Old Hwy 77. Traffic headed to businesses on Commercial Park Road as well as business located north along Old Hwy 77 will be detoured through Wahoo. This phase is estimated to be completed mid-late August.


Phase 4 (Shown as PHASE 2 on the NDOT info sheet) will consist of work in the middle of the roundabout. Access to and from US-77 to Hwy 109 and Old Hwy 77 will be limited to right-turn only. This phase is estimated to be completed the end of October/early November.

Phase 5  (Shown as PHASE 3 on the NDOT info sheet) will construct the north portion of the roundabout. This means access to and from Hwy 109 will be closed and traffic will be detoured. This phase estimated to be completed mid-late November.

Phase 6 will complete the project. This will include final pavement clean up, finishing, pavement marking, signage, etc. and is estimated to be completed by the middle of December.
