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

Engineering Challenges & Solutions – Major Utilities

Project Benefits to Delaware Valley Region

Interstate System Provides: • Freedom of travel, cross-country mobility • Congestion relief on local streets • Fast movement of goods and services • Defense highway system

Importance of Engineering Profession to Society

Maintaining our roads and bridges is critical to our way of life!!!

• Restored structural integrity of I-676 bridges from 22nd – 18th Street • Improved vertical clearance on expressway • Created additional park/green space • More than a bridge project…streetscape/beautification of center city for all to enjoy
