Village of Northfield | Happ Road
As the number of accidents increased on Happ Road, between Winnetka Road to Willow Road, so did the need to improve safety. Therefore, the Village of Northfield engaged with Patrick to complete a Phase I Engineering and Environmental Study that would not only improve safety for all users, but also transform the Village’s downtown into a corridor supportive of local business, community gatherings, and walkable access. After an intensive public engagement program, the Village of Northfield, Cook County Department of Transportation and Highways (CCDOTH), and the Illinois Department of Transportation (IDOT) approved the study. As part of the transformation plan, Happ Road will be converted from a 2-lane rural roadway to a 3-lane urban cross-section with center bi-directional left turn lane. At Orchard Lane, located just south of the major intersection with Willow Road and in the Village’s Downtown Center, a traffic signal was not a practical option, and a modern roundabout was selected as the preferred option. In addition to improvements to the roadway, continuous sidewalk, bike-path, and a mid-block pedestrian crossing will be included.
