Wisconsin Department of Transportation
Sub-Contractor to:  Zignego Company, Inc.
Completion:  July 2004


Scope of Project:     
The construction project was part of the traffic mitigation initiative for the Marquette Interchange Reconstruction Project.  This was the first project let as part of the major interchange reconstruction, and Vista is proud to be part of it.

Features & Challenges:

•    Importance (and even pressure!) of delivering part of the mega project first contract
•    Soldier pile retaining wall with cast in place concrete facing, structure backfill and chain link fence behind the wall
•    Challenging soil conditions
•    Difficulty of keeping the wall on the design alignment (horizontal curve) while encountering rocks driving the soldier piles

Vista’s Solution:  

Vista was responsible for construction of the retaining wall as part of the ramp widening on westbound I-94 at 28th Street. Despite the challenges Vista and prime contractor (Zignego) delivered successful project on schedule kicking off the overall success of Wisconsin #1 transportation mega project.
