An Interstate 77 bridge less than a mile south of the North Carolina border was ranked 12th for substandard bridges in South Carolina for the second year in a row by AAA of the Carolinas.
The bridge, passing over S-1441, was listed as functionally obsolete by AAA, meaning that its design is inadequate for the current traffic volume. The bridge received a sufficiency rating of 84 out of 100, the best rating on the top 20 list, but more motorists drive across it than any other bridge on the list (710,500 cars per week on average).
Angela Vogel Daley, public relations manager for AAA of the Carolinas, said the amount of traffic on this bridge is the main reason for this 40-year-old bridge’s ranking.
“Even though it may not collapse, it could still cause accidents,” Daley said.
Lee Floyd, a South Carolina bridge maintenance engineer, said the bridge is functionally obsolete because its substructure is very close to the edge of the road below. He said the bridge does not pose any safety concerns.
The top six substandard bridges in South Carolina were all on Interstate 26 in Richland, Lexington and Charleston counties. The I-26 bridge passing over CN&L Railroad, 3 miles northwest of Columbia, was the most substandard bridge on the list.
South Carolina has the lowest highway funding per mile in the country, with the fourth-largest state-maintained highway system, covering more than 41,000 miles, according to the AAA.
