Oconto Falls STH 22 Reconstruction

« Return to Project Search

This project included 1.67 miles of two-lane urban surface repairs and reconstruction beginning at West Highland Drive and ending at East Highland Drive in the City of Oconto Falls. The section of STH 22 between West Highland Drive and Cherry Avenue was rehabilitated with concrete pavement repairs, and the urban section from Cherry Avenue to East Highland Drive was completely reconstructed.

The project addressed pavement and roadway deficiencies and drainage issues and provided bike/pedestrian accommodations along the corridor. The existing pavement was over 40 years old and was distressed, and many joints were failing. Sidewalk was designed to meet Americans with Disabilities Act (ADA) guidelines in the downtown business district, and new sidewalk was added so that sidewalks now run along both sides of STH 22 for the entire corridor. Bike lanes were also added to the typical section as part of Trans 75 compliance.

Besides improving the storm sewer system along STH 22, a portion of the City’s storm sewer system receiving runoff from the STH 22 roadway had to be upgraded to meet Wisconsin Department of Transportation storm sewer design standards. This required replacing existing 24-inch storm sewer with 30-inch and 36-inch pipes for over a half-mile of residential streets to the discharge at the cliff over the Oconto River.

STH 22 was constructed in segments to minimize impacts to schools and businesses along the corridor, and pedestrian access was staged to provide access during construction. Utility coordination was critical to ensure the City water and sewer facilities could be replaced one year in advance of street construction and that relocation of new power poles and gas facilities fit with the new roadway reconstruction project in this constrained environment. Ayres provided design and construction phase services for replacement of sanitary sewer, water main, and storm sewer under a separate contract with the City. Municipal services also included topographic survey, bidding assistance, and construction staking,

Section 4(f) coordination was needed for grading impacts to Memorial Park and sidewalk replacement within the historic boundaries of property that was eligible for the National Register of Historic Places. An exception-to-standards report was prepared for less-than-minimum cross slope and for a substandard horizontal curve. A new railroad crossing was also installed.
