11. Existing Bridge Description (cont’d) Bridge No. 00245 Minimum Vertical Clearance over I-95 = 14’-2” Reinforced concrete deck with concrete wearing surface Substructure (Foundation) –Concrete abutments on steel piles –Two intermediate concrete piers and one center concrete pier on spread footings founded on bedrock Minimum Vertical Clearance over I-95 = 14’-2” Reinforced concrete deck with concrete wearing surface Substructure (Foundation) –Concrete abutments on steel piles –Two intermediate concrete piers and one center concrete pier on spread footings founded on bedrock

12. Reasons for Project Structure recommended for rehabilitation under the State Bridge Program. Structurally Deficient: –Overall Superstructure Condition Rating “4” –Jersey Barriers used to keep live loads off fascia girders –Fascia girders exhibit extensive vehicular impact damage –Girders exhibit moderate to heavy rust Functionally Obsolete: –Minimum Vertical Clearance is Substandard Structure recommended for rehabilitation under the State Bridge Program.

13. Reasons for Project Fascia Girder over SB Traffic Impact damage Fascia Girder over SB Traffic Impact damage Bearing Pads Sheared bolt due to impact damage

14. Reasons for Project Steel Girders Rust along underside of structure Steel Girders Rust along underside of structure Piers Light to moderate scaling, rust along underside of structure

15. Proposed Construction New two-span continuous multi-girder, high strength weathering steel superstructure Increased Minimum Vertical Clearance over I-95 –Existing: 14’-2” –Proposed: 16’-3” Deck will consist of cast-in-place reinforced concrete with membrane waterproofing and an asphaltic overlay. Structure Dimensions –Total Length slightly increased due to abutment modifications –Match Existing Out to Out Width New two-span continuous multi-girder, high strength weathering steel superstructure Increased Minimum Vertical Clearance over I-95 –Existing: 14’-2” –Proposed: 16’-3” Deck will consist of cast-in-place reinforced concrete with membrane waterproofing and an asphaltic overlay. Structure Dimensions –Total Length slightly increased due to abutment modifications –Match Existing Out to Out Width

16. Proposed Construction (cont’d) Pier Repair and Modification –Removal of Intermediate Piers –Reconstruction of Center Pier to form Pier Wall –Concrete Repairs to spalls and hollow areas Abutments will be modified to accommodate increased loads and raised profile –Addition of heel length –Third row of steel H-piles –Minor concrete repairs to existing abutment stems Pier Repair and Modification –Removal of Intermediate Piers –Reconstruction of Center Pier to form Pier Wall –Concrete Repairs to spalls and hollow areas Abutments will be modified to accommodate increased loads and raised profile –Addition of heel length –Third row of steel H-piles –Minor concrete repairs to existing abutment stems

21. Public Utilities Utilities at the bridge site consist of aerial facilities (electric, telecommunication and cable) and a VMS cabinet located Northeast of the bridge. CTDOT has notified the appropriate utility companies of the scheduled project. Utilities will be temporarily relocated as part of the proposed construction activities.
