Project Overview
The City of New Berlin made improvements on Lincoln Avenue to improve drainage road conditions. The work consisted of rural to rural and urban road reconstruction with new curb and gutter, ditching, intersection improvements, new storm sewer, and a new box culvert. The road was built over and through wetlands and very poor subsoils. Based on a life-cycle cost analysis using a pavement design report, the road design included multiple typical cross-sections to bridge the bad soils with various depths of pavement and geotechnical reinforements included in the final roadway plans. We worked with the DNR to design a new structure crossing a navigable waterway that addressed the eroding side banks adjacent to the roadway.
Solution Overview
Approximately 8,200 feet of roadway was reconstructed with ditches and new curb and gutter to alleviate drainage issues and improve the failed pavement. The project included traffic signal design at the intersection of Lincoln Ave. and Calhoun Rd. An extensive amount of wetlands needed to be disturbed due to the widening of the existing roadway to meet current City standards and an old, failing box culvert was replaced. Therefore, the design team worked with the DNR to obtain all necessary permits for wetlands and waterway disturbance. Other permitting included storm water management for MMSD which involved bio-swale design to meet water quantity and quality requirements.
