South Street Pedestrian Trail Underpass

WBK provided Phase I Preliminary Engineering and Phase II Final Engineering for the Kane County Division of Transportation on this federally funded bike path and tunnel project located near the intersection of Randall Road and Keslinger Road in Geneva, Illinois. The tunnel allows for pedestrian traffic to safely pass under Randall Road, a heavily travelled roadway with an estimated 50,000+ vehicles per day.

The project consists of the construction of a 12 foot diameter concrete pipe tunnel that was bored and jacked through the embankment of Randall Road south of Keslinger Road and an associated 10 foot wide hot-mix asphalt bike path on a new alignment. The concrete pipe tunnel is 140 feet in length and includes concrete headwalls at both ends. The work also included traffic signal modifications, guardrail, box culvert, tunnel lighting and landscaping.

The project was completed in the summer of 2013 and is now open for public use.
