Shallow Structure Types • Channel Bridge • Cable-Stayed Bridge with slab superstructure • Tied-Arch Bridge with slab superstructure • “Conventional beam bridge with integral supports” • Segmental voided slab
Pre-fabrication • Segmental Concrete Superstructure • Pre-cast piers • Pre-cast abutments • Pre-cast deck panels • Pre-cast bridge barrier • Temporary Bridges Bailey/Acrow
High Performance Materials • Polymer Asphalt • High Performance concrete • High Performance steel • Self-Consolidating Concrete • High Strength Concrete • Initial Overlays
Retaining Walls • Remove retaining walls, purchase additional Right of Way (ROW), Lay slope back at 3:1 • Soldier Pile, Soil Nailed or Secant Walls
Service Drive Expansion • Near Wayne State University (WSU) parking garage expand service drive over slope.
Foundations for Interchanges • Single/mono shaft • Large diameter closed in steel pipe pile • Post grouted shaft
Railway Crossings • Construct temporary railroad bridges as necessary • Diverge rail traffic onto one bridge in areas with multiple tracks • Roll in pre-fabricated bridge over short closure period • Edge girder floor beam system
Interchange Construction Staging • Build new ramps before eliminating movements • Construction Planner • Manage sequence of construction for whole interchange • Ramp Bridges • Segmental Box • Steel Box/Plate • Temporary Structures to move traffic
Advanced Contracting • Identify bridges for early construction/replacement due to poor condition • Advanced relocation of utilities Design to Minimize Future Maintenance • Eliminating expansion joints, design for continuity • Minimize number of bearings
Erection Methods • Self Propelled Modular Transport (SPMT) • Roll In • High capacity cranes • Erection Gantry
