Lucy Webb Dean Avenue Roundabout

A single lane roundabout was designed to improve this existing, high-volume intersection.  Cost, construction traffic, and right-of-way issues were some of the largest design constraints.  The design was completed that circumscribed the center circular island within the existing intersection pavement limits.  A phased traffic control plan was developed and construction alternate was added during bidding that required the contractor to leave the intersection open to traffic during construction.

• Both single & duel lane roundabouts were analysed to determine optimum traffic flow and minimize right of way needs
