US 41 / 43 Interchange, Green Bay


This project, estimated at $141 million was divided into 3 major contracts, reconstructed the I-41/I-43 interchange including I-41 between Memorial Drive and Lineville Road.  The project included three steel tub girder flyover bridges, one steel plate girder bridge, nine concrete girder bridges, 11 wire faced MSE walls with concrete tip up panels, 20 sign structures, multiple temporary retaining walls and extensive temporary widening to maintain traffic through the interchange.

This project included unique geotechnical challenges requiring the use of various geotechnical monitoring devices, strip drains and staged embankment construction.  The bridge construction included owner-supplied steel tub and plate necessitating the coordination of over 400 deliveries of girders, bearings, diaphragms and connection bolts/plates.

This project included over 1.2 million cubic yards of embankment construction, over 170,000 linear feet of piling, over 80 substructure units and 660,000 square feet of bridge deck construction, including polymer overlays.

As part of a joint venture Kapur & Associates assisted in the overall administration of the contract along with inspection, material testing, erosion control compliance, traffic control compliance, utility coordination, project record keeping, and inter-agency coordination.
