The City of Hammond, located in Lake County, Indiana, is developing a federal-aid project to reconstruct and widen Chicago Street (formerly known as State Route (SR) 312) through the city from South Brainard Avenue, on the Indiana border with Illinois, to White Oak Avenue, at the eastern limits of the city. The entire length of the proposed project is approximately 2.1 miles. Former SR 312 coincides with three separate streets as it traverses the project study area, including Gostlin Street, Sheffield Avenue, and Chicago Street. The project limits, from west to east, begin at the intersection of Gostlin Street (former SR 312) and South Brainard Avenue and continue east along Gostlin Street to the intersection of Gostlin Street and Sheffield Avenue, where the project study area continues south along Sheffield Avenue to the intersection of Sheffield Avenue and Chicago Street. At this intersection, the project study area turns east along Chicago Street to the study area’s eastern terminus at the intersection of Chicago Street and White Oak Avenue.
