Transportation Design: Rural Reconstruction

STH 73, Dodge County

KL Engineering designed a 2 mile section of STH 73 in Dodge County. The project reconstructed and rehabilitated the rural highway’s deteriorated pavement structure through an area with poor subgrade soils and a high-water table.

The design challenges included providing an improved subgrade treatment while keeping the construction limits within the existing right-of-way. Avoidance of sensitive wetlands and an archaeological site located adjacent to project was necessary. The subgrade treatment included breaker run and french drain installation.

KL Engineering completed the survey, intersection and drainage improvements, Environmental Report, and all aspects of the plans, specifications and estimates package for a shelf plan that was submitted one year prior to September 2001 letting. This $1.3 million project was constructed in 2002.
