The city will begin a major construction project on Johnson Avenue and Irwin Avenue in Riverdale that is expected to last nine months. The project will involve installing a new sewer, gas mains, sidewalks, and curbs, as well as replacing sections of the retaining wall. There may be temporary restrictions to vehicular access, parking, and driveways during construction. Notices will be provided to residents about any planned water disruptions or changes to bus routes during the project. The goal is to complete this work without major disruption to the community.
