Various Statewide Structure Replacements

The Illinois Department of Transportation needed to design replacement bridges and improve safety features at various locations throughout District 3 and 9.

HLR provided preliminary and design engineering services at 30 locations under PTB 41/9 and 148/33. The proposed  improvements included many deteriorated PPC deck beam bridges which were to be completed quickly and with minimal guidance from IDOT. Once completed, each structure featured improved safety features, an environmentally-friendly design, and minimal right-of-way requirements and future structure maintenance.
