STH 22 Rural Reconstruction and Roundabout, Gillett and Oconto Falls, Oconto County, WI
STH 22 Rural Reconstruction and RoundaboutAs part of an 8-mile reconstruction of STH 22, OTIE prepared TPP monumentation and acquisition right-of-way plats including determining the existing right-of-way and acquisition of temporary and permanent interests on 120 properties throughout the 8.5-mile project corridor. This was one of the first monumentation transportation project plats in the Northeast Region.

OTIE prepared the plans including an 8-mile reconstruction of STH 22 as well as roundabout analysis and design at three major intersections. OTIE supported the Wisconsin DOT with substantial public involvement and coordination efforts with local officials for the evaluation of three potential roundabouts. The final plans included one new roundabout.

This rural highway was reconstructed and upgraded to new construction standards. A gravel lift was placed over the existing pavement, and right-of-way was acquired throughout the majority of the project to allow for ditch and drainage grading. OTIE was responsible for recommending and implementing design modifications to the gravel lift concept based on impacts to abutting properties, cost effectiveness, and other sound engineering practices. Specific tasks include geometric design, roundabout design, right-of-way plat, and public involvement.

Eight miles of existing right-of-way were explored, researched, and remonumented where necessary. Height modernization monuments were used to define the project on the county coordinate system to match with the recorded locations of the section corners. This reduced the amount of surveying field work for the entire project.
