Project Summary:

This project consists of replacement of the existing Cliff Avenue asphalt roadway with a widened concrete roadway between Tomar Road and 56th Street. A second southbound traffic lane will be added for this stretch of roadway. Four lanes are needed to accommodate the growing traffic volumes and to eliminate the southbound bottleneck at Tomar Road where Cliff transitions from two lanes to one. Embankment will be added to the west side of Cliff Avenue to accommodate the roadway widening. Utility improvements include water main replacement, sanitary sewer repairs, storm drainage replacement, lining of a culvert crossing between 54th Street and 56th Street, street light replacement, fiberoptic line installation from Tuthill Park to 57th Street, and private utility improvements.
