Interstate 55 at Airport/Lockport Road and
Illinois Route 126 at Essington Road

The Potential I-55 Improvements at Airport Road and at IL 126/Essington Road Study Area is located entirely within Will County and communities adjacent to the project include Romeoville, Bolingbrook, Plainfield and Joliet.

The communities in and around the project areas, have grown rapidly in recent years, and this growth is projected to continue. Traffic volumes have doubled and, in some cases tripled along sections of I-55 since the mid-1980’s. This traffic adds to congestion experienced in downtown Plainfield, on the west side of Bolingbrook and on Weber Road in Romeoville.

IDOT has designated this project as one that will utilize principals of Context Sensitive Solutions (CSS) as part of a robust public involvement process.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.
