The proposed project involves the development of a four-lane highway facility through the Iowa "Great Lakes Region," replacing an existing two-lane roadway. The project, which would follow the general alignment of existing U.S. 71, would begin just south of Fourteenth Street in Milford and extend northerly to the west junction of Iowa 9, in Spirit Lake. Within the incorporated areas of Milford, West Okoboji, Arnolds Park and Okoboji it is proposed to construct 49-foot back-of-curb to back-of-curb urban sections. In the rural area between Milford and West Okoboji, a 48-foot rural undivided section with 10-foot stabilized shoulders is proposed. The portion of highway from Okoboji northerly to Iowa 9 in Spirit Lake would be constructed as a four-lane divided facility. The rural cross section in that area would utilize certain portions of the existing highway, resurfaced with asphaltic concrete, as the two southbound lanes. The design would also provide for an approximate 20-foot median with 10-foot outside and six-foot inside stabilized shoulders. The urban cross section, within Spirit Lake, would utilize a 16 to 20-foot raised median and 10-foot outside stabilized shoulders. Sidewalks would be constructed within the project area to accommodate pedestrian traffic, where warranted, according to established Iowa D.O.T. policies and procedures. Total length of the proposed project is approximately 7.1 miles.
