2LMN, Inc. is the prime consultant on this bridge replacement project for the Fairfield County Engineer. The project proposes to replace the deteriorated single-span, concrete box beam bridge with a similar single span, concrete box beam bridge. 2LMN was responsible for collecting all survey information needed to facilitate the design, all the bridge design and plan detailing including the bridge hydraulic and scour analyses, all of the roadway and drainage design and detailing, and the overall completeness of the project.

The goals of the project are to provide a cost-efficient replacement for the deficient bridge and improve the vertical profile within the project’s limits so that it was more in-line with the current speed limit. 2LMN has been able to meet both goals, despite the high erodible soils at the bridge location. 2LMN proposed moving the proposed structure to the north by 8-ft which provide a better alignment with the waterway below, avoided having to constructed on top of the existing bridge foundation locations and allowed for the use of stub abutments at each location instead of needing one wall type abutment.
