US 51, WIS 64, Merrill, Lincoln County


US 51 - WIS 64 southbound ramp to northbound ramp

WIS 64 - Pine Ridge Avenue to WIS 17

Merrill, Lincoln County


Some of the needs that have been identified at this location include:

  • The pavement on WIS 64 at the interchange is deteriorating.
  • The abutment of the northbound US 51 bridge over WIS 64 requires repairs.
  • The traffic demands at the WIS 64 intersections with the US 51 interchange ramps and the WIS 64 intersection with WIS 17/County W are creating inefficient operations at the intersections.

Proposed solutions

We are evaluating several alternatives to address the identified needs. These alternatives include:

  • Repairing the northbound bridge abutment of US 51
  • Replacing the pavement on WIS 64 between Pine Ridge Avenue and the WIS 17/County W intersection.
  • Improving the intersection operations of the US 51 ramp terminals and the WIS 64/WIS 17/County W intersection

Ramp terminal and intersection improvement alternatives 

US 51 Southbound Ramp Terminal

  • Stop signs at the off-ramp stop (current condition)
  • Install traffic signals
  • Construct a roundabout

US 51 Northbound Ramp Terminal

  • Install traffic signals
  • Construct a roundabout

WIS 64/WIS 17/County W intersection

  • Two-way stop at WIS 17 and County W (current condition)
  • Install a four-way stop
  • Construct a roundabout

Traffic impacts

Depending on the alternative selected, traffic impacts may vary, but will generally consist of:

  • US 51, WIS 64, WIS 17, and County W will remain open to traffic. Motorists can expect to encounter possible lane closures, flagging operations, traffic shifts, and reduced lane widths.
  • Northbound and southbound US 51 traffic may be reduced to a single lane. All traffic may be shifted into the southbound lanes during the northbound US 51 structure work.
  • Some weekend and nighttime construction activities may be necessary.
  • Construction will be scheduled to avoid peak travel weekends such as holidays and special events.
  • Interruptions in access may occur temporarily at driveways near the WIS 64/WIS 17/County W intersection.

Current schedule

  • Environmental documentation - May 2017
  • Third local officials meeting - Spring/summer 2017
  • Second public involvement meeting - Summer 2017
  • Real estate acquisition (if needed) - 2017 to 2018
  • Construction currently scheduled - 2020**

**WIS 64 construction could occur as early as 2019. Work on the US 51 bridge abutment could begin as early as fall 2017.**
