Overview

Project Description Design Requirements Project Approach Design Solution

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

Project Description (1)

Project Description (2)

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

Project Description (3)

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

Project Description (4)

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

Design Constraints

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
