  3. Overview • Project Description • Design Requirements • Project Approach • Design Solution

  4. Project Description (1) • Naval Support Activity (NSA) Crane • Located in Martin County, Indiana on 100 square miles • Employs nearly 4000 people (2nd largest employer in Southwestern Indiana) • Constructed in the early 1940s

  5. Project Description (2)

  6. Project Description (3) • Carries H-161 over Boggs Creek • Constructed in 1942 • Partially reconstructed in 1986 • Total length ~ 76 ft • Total width ~ 24 ft • Travel width ~ 22 ft

  7. Project Description (4) • Two-year inspections indicate need for replacement of Bridge 2153 • Holes in timber from insect damage • Corrosion on underside of deck • Poor wing wall pile condition • Severe checking

  8. Design Constraints • Have minimum 60-yr life • Pass the 100-yr flood • Have only one span if economically feasible • Have low maintenance cost • Meet or exceed INDOT and AASHTO standards • Minimize cost

  9. Client Requirements & Project Approach • Determine and assess design options • Recommend most desirable option • Design of replacement structure and approaches • Provide detailed construction plans and cost estimate • Provide necessary permitting information

  10. Existing Conditions

  11. Existing Conditions • Site assessment • Maps • Soil survey • Wetlands • Floodplain ` `

  12. Bridge Material Options • Materials • Prestressed concrete • Concrete box culvert • Steel • Timber • Basis of Consideration • Initial cost • Lifespan • Maintenance cost • Constructability • Aesthetics

  13. Decision Matrix

  14. Geotechnical Investigation N BRIDGE

  15. Geotechnical Investigation Elevation (feet)

  16. Hydrologic Study • Drainage Area: DA = 2.58 sq mi • Slope: SL = 69.1 ft/mi • 100-yr flow rate: Q = 1910 cfs

  17. Hydraulic Study • 100-yr flood elevation: 478 ft • Proposed bridge lowers 100-yr elevation by 0.11 ft

  18. Structural Design • Standard 33” INDOT parapets • 8” cast-in-place concrete deck • 5 Type I bulb-tee prestressed concrete girders
