Lane closures are expected on Dorothy Drive between La Salle Drive and Polk Street due to a major road reconstruction project lasting through fall of 2020. From the week of Sept. 23 to early December, the southbound lane will be closed. The road’s reinforced concrete pavement will be replaced, curb to curb, and a new storm sewer will be installed, as well as new water mains, new wastewater mains, directional ramps, and sidewalks as needed.
