River & Roberts Roads

Lake County, IL

SUMMARY

MTJ Roundabout Engineering provided the roundabout operational analysis, traffic analysis, horizontal geometrics, and signing and pavement markings for Phase I (IDS) and Phase II of this challenging and constrained intersection in this developing area of Lake County, IL.

MTJ Engineering’s design experience played a pivotal role in finding a roundabout design solution that provides exceptional LOS for both the short- and long-range traffic flows projected for this intersection, with ease of capacity expansion in the future.

In addition to addressing the long-term capacity needs, the design also accommodates access for the adjacent residential area, and balances impacts with sensitive environmental areas located in the vicinity, including Lake County Forest Preserve Land.

HIGHLIGHTS

  • Designed for ease of future expansion (no curb changes)
  • Balanced impact with constraint of sensitive environment nearby
  • Accommodates access for adjacent residential area
  • High-speed approach
  • IDS data
