K. Singh & Associates, Inc. (KSingh) was retained by Strand Associates, Inc. to provide design services for the reconstruction project on STH 100, from College Avenue to Edgerton Avenue, in the Village of Hales Corner in Milwaukee County.

KSingh’s portion of the project is final roadway and traffic signal design and drafting from Abbott Avenue to north of Edgerton Avenue, the northern project limit. In addition, the project also includes the extension of existing culvert on STH 100 over Whitnall Park Creek just south of Whitnall Park Drive. Jeremy Hinds, PE, is the Project Manager, Moaz Khan, PE, is the Lead Roadway Design Engineer, Mukesh Jain, PH.D, is the Lead Traffic Engineer, and Vincent DiFrances, EIT, is the Lead Structural Engineer for this urban reconstruction project. The traffic portion of the project includes temporary and permanent traffic signal design for the intersection of STH 100 and Edgerton Avenue, and permanent signal design for Abbott Avenue. The roadway portion of the project includes final design, modeling, drafting, and plan production for the 2,200-ft segment.

Key challenges include raised median sections, the high frequency of driveways, close proximity to the I-43 Ramps, and storm sewer design. Additional challenges include staging the construction to minimize interruption to traffic, utility coordination and relocations, and getting the neighborhood public on board with the proposed improvements.

KSingh’s segment traverses two (2) intersections, both of which are signalized. The segment also includes two freeway ramps. The modeling for these intersections and ramp connections is being performed in Civil 3D. Additionally, the traffic control plan includes maintaining both directions of traffic at all times.

KSingh is also responsible for the Pavement Marking and Signing,
and Erosion Control plans for the segment. The project is currently moving towards final design.
