Engineering Challenges – Existing Bridges
• 7 bridges – 2 span, non-composite prestressed concrete adjacent box beams
• Bridge superstructures rated as structurally deficient / require replacement
• Center piers heavily deteriorated / require replacement
• Bridge abutments in fair condition / high chloride ion contamination
• Minimum vertical clearance 13’-10”
• As-built Site Survey
• Determine Base Flood Elevation (BFE)
• Structural & Mechanical Inspection/Evaluation
• Design Plans
• Local & State Approvals
• Contract Bidding/Construction Estimates/Local Building Permits
• Construction
14’-6”
Engineering Solutions – Proposed Bridges
• Single span steel plate girders selected eliminating piers and improving clearance to 14’-6”
• Abutments retrofitted and repaired, electrochemical chloride ion extraction proposed
