Load Rating and Rehabilitation of the New River Gorge Bridge
Opened in 1977, the 3,030 foot New River Gorge Bridge in Fayetteville, West Virginia, is the second highest bridge in the United States and among the largest steel arch bridges in the world. Burgess & Niple has performed inspections of this structure for the past six years, and recently completed an analysis and load rating of the bridge.
This webinar will discuss the methods used for the analysis that were conducted using a three dimensional model in Midas Civil software. The model incorporated wind and temperature loading, along with nine different rating trucks. The results were used to calculate rating factors for more than 4,500 members and over 1,800 gusset plates and connections. The rehabilitation plans, which are currently in development, also will be discussed. These plans include steel repairs to the superstructure and substructure as well as bearing rehabilitation.
