• Four-Span, Continuous Steel Multi-Girder Structure built in 1958
• Carries one lane of traffic in each direction– Estimated Average Daily Traffic (ADT) on Flat Rock Hill Road ~116 vehicles (2007)
– ADT on Interstate 95 under Bridge No. 00245 ~67,900 (2009)
• Structure Dimensions– Total Length = 173’
– Overall Width = 45’ 7”
– Roadway Width = Originally 40’ 0”
Reduced to 26’ 5” due to concrete
barrier curb along Eastern side for
girder protection

• 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

Reasons for Project 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

Proposed ConstructionProposed 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

Bridge Cross Section
Public UtilitiesPublic 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.
