Buncombe County, NC: Long Shoals Road Interchange Design Build (NCDOT)




Prime Contractor




Wilbur Smith Associates




October 2010

The Long Shoals Road Interchange reconstruction project is located in Asheville, NC and is owned by the North Carolina DOT. The project consisted of the design and construction of 1.01 miles of Long Shoals Road, 0.70 miles of I-26, and the reconstruction of the I-26 / LSR Interchange. The project required 175,000 CY of excavation and 8,850 LF of storm drainage installation ranging from 15 IN to 36 IN in size. Moreover, three MSE walls totaling 23,500 SF and one 6,000 SF anchored soil nail wall were constructed on the project. The new interchange included a 256 FT single span steel girder bridge containing 1,500 CY of reinforced concrete with MSE wall abutments. Furthermore, there is a three span bulb tee beam bridge containing 2,100 CY of reinforced concrete crossing the French Broad River. Due to the high traffic volumes great detail had to been given to the phasing / traffic control design and construction on the project. Additionally due to high traffic volumes a significant amount of our work had to be completed during nighttime hours.
