Public Comment PeriodMarch 1 - March 31, 2018

The proposed project would widen and resurface 12.67 miles of Nebraska Highway 97 (N-97) between Tryon and Mullen in Hooker County.

Information regarding the proposed project will be made available on the NDOT website at http://dot.nebraska.gov/projects/future-projects/ by clicking on the “Tryon - Mullen” link.

The construction of a retaining wall allows for the widening of the roadway without impacting the river.

Purpose and NeedThe purpose of the proposed project is to preserve the transportation asset of N-97, improve the reliability of the transportation system, and perpetuate the mobility of the traveling public. The need for this proposed project is based on the condition of the existing roadway and recent inspections showing that rehabilitation would be required.

Scope of WorkProposed improvements on N-97 would include a minimum 24-foot-wide surfaced top, 6-foot-wide earthen shoulders, curb and flume construction, removing and replacing guardrail, and surfacing underneath guardrail. To facilitate the roadway widening without impacting the Dismal River, a 400-foot-long retaining wall would be constructed on the east side of the highway between MM 53.38 and MM 53.46.

Right-of-WayThis project would require the acquisition of additional property rights which could include new right-of-way (ROW), permanent easements (PE), and/or temporary easements (TE) throughout the project area. Access to adjacent properties would be maintained during construction but may be limited at times due to phasing requirements.

Potential ImpactsMinor wetlands impacts are anticipated; no mitigation is anticipated.

Estimated CostThe cost of the proposed project is approximately $8.5 million and would derive from federal and state funding sources.

Construction ScheduleConstruction is tentatively scheduled to begin in March 2020 and completed in May 2021.

Accommodation of TrafficA majority of the project would be constructed under traffic with lane closures controlled by appropriate traffic control devices and practices. Full closure would be needed from MM 53.38 to MM 53.46 for approximately three weeks to facilitate sheet pile driving operations for a retaining wall. The temporary detour route would utilize N-2, US-83, and N-92.
