MDOT ACTT Workshop Structures I-94 From I-96 to East of Connor Participants Steve Stroh, URS Corp Vijay Chandra, Parson Brinckerhoff Raj Ailaney, FHWA Gary Jakovich, FHWA Jon Nekritz, FHWA Phil Grotenhuis, MDOT Matt Chynoweth, MDOT Terry Lavoy, MDOT Wesley King, MDOT
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
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
