Project Information • WIS 79 is a rural minor arterial highway that provides a north/south route for the Dunn County communities of Connorsville , Boyceville and Sherman . • Average of 1,800 vehicles per day. • WIS 79 crosses over Coon and Clack creeks between the village of Boyceville and its terminus with US 12. • Existing structures were constructed in 1936. • Structures are made of concrete decking supported by steel beams and a timber-pile substructure. • Last significant bridge repair was done in 1987.

Project Location

Purpose and Need • The purpose of this project is to address the deteriorating structural elements of both bridges . • The need for this project is to address the following: • Bridge deck deterioration • Structural support deterioration • Substandard bridge railing

Purpose and Need • Bridge deck and steel beam deterioration • Clack Creek Bridge, B-17-0369, typical • Coon Creek Bridge, B-17-0368, spalling at concrete soffit. deteriorated steel girder and timber pile substructure view.

Purpose and Need • Timber-pile structural support deterioration • Typical condition of timber-pile supports found at both bridges.

Purpose and Need • Substandard bridge railing. • Typical railing design found at both structures.

Proposed Improvements 1. Bridge – construct new bridge consisting of a concrete deck and structural support elements. a. Railing will be solid concrete parapet wall. b. Width of bridge will be widened by 4 feet. 2. Roadway – reconstruct asphalt roadway approaches to each bridge, replace existing guardrail, replace pavement markings and signs. a. Roadway alignment will match existing. b. Change in roadway vertical profile is anticipated: i. Raise of approximately 1.5 feet at Coon Creek crossing. ii. Raise of approximately 2 feet at Clack Creek crossing. iii. Change in elevation needed to install standard concrete railing.

Proposed Improvements Coon Creek Bridge – Estimated Construction Limits N 350’ 550’

Proposed Improvements Clack Creek Bridge – Estimated Construction Limits N 325’ 575’

Construction Staging • WIS 79 will be closed to through traffic, and a detour route will be implemented. • Detour route will utilize US 12, WIS 25 and WIS 170. • Residents on 750 th Ave., 390 th St. and 770 th Ave. can access the detour route via County J. • Anticipated closure duration is one construction season.

Detour Route ` NORTH TERMINUS SOUTH TERMINUS

Access Modifications • No permanent change to existing accesses on WIS 79 is proposed. • Access to adjacent properties will be maintained at all times. • Some driveway accesses near these bridges will need to be raised to match raised centerline elevation of WIS 79.

Real Estate Needs • Coon Creek Bridge N (B-17-0368) • Permanent right of way along the west side of WIS 79 for grading and embankment construction. • Temporary easements along the right of way for grading and tying in slopes.

Real Estate Needs • Clack Creek Bridge N (B-17-0369) • Permanent right of way along the west and east side of the highway right of way. • Temporary easements along the right of way for grading and tying in slopes.

Real Estate Needs • Acquisition process • WisDOT will acquire real estate. • Individual property owner meetings will be held. • Real estate acquisitions will begin in 2021. • Landowner rights brochure on the project website.

Current Project Schedule • Surveys and initial agency coordination– Late 2018-19 • Local official meetings – May 2020 • Public involvement – July 2020 • Final environmental document – September/October 2020 • Final right of way plat – November 2020 • Right-of-way acquisition – Winter 2020 through 2021 • Final plans – May 2022 • Construction – As early as spring/summer 2023; currently scheduled for 2025
