US Route 14 – Grade Separation | Illinois Department of Transportation

IDOT tasked Knight with providing design services for the reconstruction of 2.2 miles of US Route 14 in Cary, Illinois. The Chicago North Western/ Union Pacific Railroad tracks crossed over Route 14 on an existing structure and intersected with Cary/Algonquin Road. The at-grade intersecting at Cary-Algonquin Road was eliminated, which required the design of two new permanent bridges. Knight prepared TS&L and contract plans for the two new bridges, a temporary bridge and a temporary shoofly.
