Farnsworth Group was selected by the Illinois State Toll Highway Authority to provide design services for the widening of southbound Veterans Memorial Tollway (I-355) from north of 71st Street to south of 75th Street.  

The project scope of work includes:

  • upgrades to ITS communications, noise abatement wall and retaining wall construction
  • installation of guardrail; and
  • maintenance of traffic during construction.  

Farnsworth Group’s services included the use of four subconsultants.  Our scope includes the preparation of multiple submittals from a Concept Design Report to a Final Design package. The conceptual design phase includes the Concept Design Report along with corroborating plans for review including a drainage concept report, environmental evaluation document and budget estimate. The Final Design package contains all necessary documents for construction of the project, including roadway design plans, structural design plans, drainage design plans, erosion control plans, barrier warrant analysis for the placement of guardrails and concrete barriers, noise analysis, geotechnical analysis, maintenance of traffic plans, construction details and specifications, construction schedule and estimate.
