Koontz Lake Dam & S.R. 23 Reconstruction
Starke County, Indiana
The project included realigning S.R. 23 and providing a bridge over the new labyrinth weir spillway for Koontz Lake. Super-elevated curves were required at bridge ends. The bridge is a continuous composite prestressed concrete I-beam bridge with two spans at 68-ft. - 3-in. The substructures were built integral with the labyrinth spillway structure and the existing spillway and road were removed. LFA coordinated and worked closely with IDNR and INDOT LaPorte District, right-of-way, utility and environmental services to advance this non-standard project. The project had to incorporate design criteria of the IDNR for the dam and spillway portions of the project and the INDOT design criteria for the bridge and new roadway. LFA provided the construction inspection for many facets of this project. The LFA team worked with INDOT and IDNR inspectors during the construction to cover 21 pertinent work items.
