South Old 3-C Highway
Bridge over Hoover Reservoir
Rehabilitation (ARRA) (DEL-CR24-5.02)
Construction on the bridge over Hoover Reservoir is now complete and the road is open to traffic.
06-18-10 Construction Update:
The Old 3-C Highway bridge over Hoover Reservoir in Galena will close beginning July 6 for approximately 2 months. Traffic will be detoured using Lewis Center Road to S.R. 3 to S.R. 37 (in Sunbury), and the reverse.
The existing bridge was built in 1954 as part of the original construction of Hoover Reservoir. The bridge is a five-span steel beam bridge spanning a total of 197 feet, crossing Little Walnut Creek and the northern portion of Hoover Reservoir. Over the last several years, the County Engineer noted deterioration in the steel beams and concrete deck during annual inspections. This led the Engineer's Office to add the project to the County's Highway Capital Improvement Plan to investigate ways to ways to correct the deficiencies. The project was a high priority to ensure that the bridge will continue to serve this growing area of Delaware County.
Scope of Work:
Rehabilitation of the bridge including replacement of the deck and superstructure on existing foundations. Minimal roadway approach work. The new bridge has a wider deck providing additional room for vehicular, pedestrian and bicycle traffic.
Road Closure Information:
Preliminary engineering: May to July 2009
Final design (through design-build contract): November 2009 to May 2010
Construction: July to September 2010
The project site is located on South Old 3-C Highway (County Road 24) in the Village of Galena, about 1/4 mile southwest of downtown.
Purpose and Need of the Project:
The purpose of this project is to provide for the safe and efficient movement of vehicular and pedestrian traffic on South Old 3-C Highway over Hoover Reservoir by:
- Improving structural capacity of the bridge, and;
- Correcting roadway geometric and safety deficiencies in accordance with current design standards.
The bridge is classified as "structurally deficient" according to National Bridge Inspection Standards due to deterioration of the steel beams and concrete deck. The roadway width of the bridge is less than the required minimum prescribed by current design standards. In addition, the existing bridge railing is not an approved crash tested design.
Evaluation of Alternatives:
Conceptual Bridge Alternatives:
Several conceptual alternatives meeting the purpose and need for the project were considered for the project, including a full replacement of the bridge, however, were not deemed feasible for further analysis.
Feasible Bridge Alternative #2 (Major Rehabilitation):
The only alternative deemed feasible that satisfies the Purpose and Need of this project is a major rehabilitation including replacement of the bridge beams, deck and modification to the abutments. The rehabilitation costs significantly less than a full replacement and meets all applicable current roadway and bridge design standards.
Typical bridge section (standard parapet railing shown - other options are available and being considered):
