Powell’s Murphy Parkway Extension Will Soon Bring Relief to Crowded Downtown Intersection

Progress continues on the Murphy Parkway Extension project in Powell. The extension of the existing Murphy Parkway from its current no outlet terminus to Liberty Street south of downtown will serve as a downtown Powell bypass, eliminating traffic congestion at the four corners intersection and improving traffic flow along Olentangy and Liberty streets. EMH&T has provided a range of professional services to the City of Powell on this project, which includes an approximate 1,000 foot roadway extension with gravity retention walls on either side, two new box culverts, design of a new detention basin with a man-made wetlands, a new bio-detention basin, and landscape design for a variety of decorative elements along the roadway’s course, including street treescape, stone pillars, and both white vinyl fencing and decorative black metal fencing at the roadway’s terminus at Liberty Street.

In addition to the civil engineering design, EMH&T disciplines working on the project included survey, structural, environmental, water resources, traffic, rail, landscape architecture, and construction inspection. The project is scheduled for completion in the fall; however, thanks to the efficiency of the contractor the project is currently ahead of schedule and is anticipated to be completed and open to the public by late summer. EMH&T will then provide traffic monitoring and an additional traffic study one year after project completion to determine what, if any, changes are required to traffic controls in and around the roadway. EMH&T is also assisting the City of Powell with its “Keep Powell Moving” campaign, which includes a series of public workshops to present and discuss a variety of other possible traffic improvements in the downtown area to the public.
