Bridge 330
Inspection and Repair Designs
After performing an NBIS inspection of Bridge 330 on Old Greensboro Road, A&O alerted the City of Winston-Salem to some critical findings. A portion of the bridge was closed off to traffic until repairs could be made. Within a short time, we worked with a contractor to design repairs for the bridge and provided construction observation services for the repairs.
For two adjacent beams in spans 1 and 2, there was extensive corrosion in the beams' bottom flanges and holes in the web. The team designed a system to support the damaged beams while repairs were made by cutting out the corroded section and welding in new steel sections.
A design-build project was the quickest way to get the entire bridge back open to traffic. We worked with the contractor to provide an engineering drawing with repair details and temporary shoring design. We addressed review comments from the City and inspected and certified the repairs upon completion of the work. Ω
