SUMMARY AND RECOMMENDATIONS

The conceptual design for the roundabout was completed in 2009, but due to lack of funding, the City did not enter into a design contract with BKF Engineers for the development of construction-ready plans, specifications and estimates (PS&E) for the roundabout until 2016.
