Township Road 208 over Branch of Little Creek

Hutchison Engineering, Inc. was selected by the Brown County Highway Department to provide Phase I and II engineering services for the replacement of the structure carrying Township Road 208 over a Branch of Little Creek. The project is located approximately 4.5 miles north - northeast of Versailles, Illinois. Township Road 208 (1550 E Road) is classified as a rural local road with an average daily traffic of 175.

This project involved the removal of the existing single-span structure consisting of a reinforced concrete deck on steel channel beams supported by closed concrete abutments. The existing structure was 21 feet in length and 17 feet in width and showing signs of distress in the superstructure and substructure elements. This structure was experiencing a significant amount of scour around the abutments and along the approach roadway from the south. Little Creek flows parallel to Township Road 208 prior to its confluence with the project stream immediately downstream of the project structure. The replacement structure is a single-span precast, pre-stressed, 21-inch concrete deck beam structure supported on concrete spill-thru abutments. The new structure is 51 feet in length and 24 feet in width with no skew. The project also included channel and roadway front slope rip rap protection in the area where Little Creek parallels Township Road 208. The project was constructed under full road closure.
