US Route 67 is a major corridor extending over 220 miles from southwestern to northwestern Illinois. Wanting to provide motorists with improved roadway, intersections and bridges has led the Illinois Department of Transportation to reconstruct the corridor. The entire project is broken into multiple stages to minimize disruption to traffic.
Oates Associates provided Phase II engineering services for the design of the US 67 Jerseyville Bypass. The project encompasses over 5.5 miles of new expressway on new alignment, which will carry US 67 around the City of Jerseyville. The Bypass will be a four lane divided expressway with full access control.
Work included design of an interchange at IL 16 east of Jerseyville and one flyover structure north of Jerseyville. Also included are frontage roads, two connector roads and realignment of three cross roads. Within the project limits are twelve bridge structures. These include four sets of mainline dual structures (1 set of curved girder structures) and three grade separation structures on three cross roads. Work also included a drainage report for the design of 40 cross road culverts and the design of the roadside ditches and median storm structures.
