Abonmarche provided the field survey and engineering design for the reconstruction of Main Street from the St. Joseph River Bridge to Battell Street. Main Street was formerly Indiana State Road 331 and had four existing traffic lanes. This project provided for four continuous traffic lanes and a continuous left turn lane. The new construction also included a new storm sewer, water main, concrete pavement with curbing, sidewalks, and ornamental street lighting.
The storm sewer system was designed to accommodate the drainage from the adjacent neighborhood to the west at a future date. A new traffic signal system was installed at the Mishawaka Avenue intersection with a video detection system, an uninterruptable power supply unit, and an optical preemption traffic control system for emergency vehicles. The project was designed to be built under traffic with one lane open in each direction for 97 percent of the construction period. Pedestrian access was provided to Mishawaka’s only local drug store, a convenience store, a local leather specialty shop, and a school.
