NCI was responsible for the conceptual design and developing pertinent engineering data for the OPWC funding application. After the funding was approved, NCI performed the survey and design of this project. The design involved reconstructing and widening 2 lanes of asphalt roadway to 3 lanes, including a center turn lane, for 2,742 ft. of Spring Valley Pike in Montgomery County, Ohio. Drop lanes for right turns at all of the intersections were also added. The project involved a variable width plan and overlay of the existing roadway already set up for the proposed three lane width. The roadway was designed to accommodate the County thoroughfare plan with the potential for future widening to 5 lanes, thus all storm water drainage appurtenances were sized for a 5-lane design. Storm sewer improvements involved a hydraulic capacity analysis to correlate existing drainage with proposed drainage.
