Walker Consultants provided restoration consulting services for the elevated roadway at Piedmont Triad International Airport (GSO). The quarter-mile-long structure includes short-term parking and was built in 1982 along with the airport terminal. The 35-plus-year-old sidewalks and roadway topping were in poor condition and continuously deteriorating, despite previous repairs. The sidewalks, crosswalks, tunnels, and stairs were also not compliant with current codes and standards.

Walker completed a condition appraisal of the elevated roadway and presented the Airport Authority with various options for repair. Walker then developed construction documents to remove and replace the deteriorated concrete topping, sidewalks, expansion joints, joint sealants, and tunnel coatings. Walker phased the plans to minimize disruption to airport operations, including maintaining AASHTO HS-15 truck traffic during construction.

New lightweight concrete sidewalks, landscape planters, and decorative aluminum guardrails around the upper-level overlook add visual appeal and make the area more comfortable for pedestrians. Improved crosswalks and dedicated parking for delivery vehicles enhance safety and accessibility. New tunnel handrails, stair guardrails, and detectable warning surfaces on curb ramps meet current codes and standards. The pavement markings and signage are now MUTCD compliant.

Thanks to Walker’s restoration consulting, the elevated roadway at Piedmont Triad is safer and more attractive, and it can continue to serve the airport for years to come.
