Airport Road & IL Route 126 / I-55 Interchange Study

Romeoville, Bolingbrook & Plainfield, Illinois

V3 provided Phase I engineering services meeting NEPA requirements for two full-access interchanges on I-55 in Will County, Illinois. Our services included traffic projections, traffic modeling, geometric studies, interchange and intersection design studies, access justification report, environmental assessment, combined design report, traffic management analysis, bridge condition evaluations and location drainage study. The public involvement program followed the principals of context-sensitive solutions and included six community advisory group meetings, three public meeting open houses and a public hearing. Key challenges included modifying an existing partial interchange to provide full access in both directions, in a corridor surrounded by wetlands.
