The intersection at N. Franklin and Cambria Streets is a five-legged intersection that experiences delayed travel time and has had several accidents. The four-light setup is known to create confusion among drivers who have at times displayed uncertainty with the turns they’re allowed to make at the intersection.
The project is multimodal in that vehicles, buses, pedestrians, and bicyclists are being accommodated and it will have a positive impact on the potential passenger rail station on N. Franklin Street. The completed project will eliminate the fifth leg, improving safety and mitigating congestion.
HOW WE HELPED
McCormick Taylor, along with the Town of Christiansburg and VDOT, performed a value engineering study for the project. The study followed VDOT’s value engineering process and used creative thinking to develop innovative ideas and emphasized improving project quality, eliminating unnecessary cost, and reducing overall life-cycle cost.
Our design team met with Christiansburg and VDOT staff and reviewed the project’s critical design and construction elements and developed draft recommendations. Some of the recommendations included items such as identifying an onsite area for excess earthwork, use of alternate retaining wall systems, and elimination of a temporary traffic barrier service during construction.
McCormick Taylor developed intersection reconfiguration alternatives to greatly improve capacity and safety. Conceptual designs, operational levels of service, and estimates were presented to the Town and VDOT early in the scoping phase. In the beginning of the design process, we coordinated with Norfolk Southern RR to ensure necessary concurrence and agreements would be in place prior to beginning right-of-way phase. We’ve also worked closely with the Town and local businesses to address concerns regarding median closures, entrance locations, circulation, etc.
The project is scheduled to begin right-of-way acquisition in Spring 2018 and construction must begin by June 2019 to fall under old SWM regulations. To meet this aggressive schedule, our team will be providing right-of-way acquisition services, a service the town originally intended to do in-house.
