This project provides for the rehabilitation of the existing Gregg Road Bridge No. M-0119 over the Hawlings River Tributary in Brookeville. The existing bridge, built in 1958, is a single span (18') steel beam with asphalt filled corrugated steel plank deck structure carrying a 17'-6" clear roadway with no sidewalks. The proposed rehabilitation includes the removal and replacement of the existing bridge superstructure with new galvanized steel beams and concrete deck. The proposed Gregg Road Bridge will reuse the existing bridge abutments and clear roadway width will remain the same. The road and bridge will be completely closed to vehicular traffic during construction and traffic will be detoured.

The roadway Average Daily Traffic (ADT) is approximately 420 vehicles and the roadway capacity will not change as a result of this project.

The Bridge Design (509132) project encompasses all required design work for this project, which will be completed in FY26. Construction is scheduled for summer 2027 and will take approximately 4 months. A full bridge closure is anticipated to last 3 months.

The proposed rehabilitation work is necessary to provide a safe roadway condition for the public. The 2022 Bridge Inspection Report indicates that the bridge steel beams are in poor condition with up to a quarter of an inch deep pitting throughout the top and bottom flanges and areas of 100 percent section loss at beam web ends. The bridge is considered structurally deficient and functionally obsolete. The bridge is currently posted for a 62,000 lb. limit for a single-unit truck and 80,000 lb. limit for a combination unit truck.

The design costs are covered in the Bridge Design Project (CIP 509132). This project does not qualify for federal aid since the existing bridge span is less than 20' long.

A pedestrian impact analysis has been completed for this project.
