King County Department of Transportation is closing the South Park Bridge Saturday and Sunday for sidewalk repairs. But as Aimee Curl reported in the run-up to Proposition 1's miserable failure, the 76-year-old structure faces closure in 2010 because: "All substructure units exhibited concrete deterioration, spalling, delaminations, leaching, cracks, and abrasion. In some areas the concrete is soft and easily removed with a hammer.... Previously noted exposed reinforcing has corroded and provides no structural strength."
Fixing the sidewalks brings to mind certain cliches about rearranging deck chairs on the Titannic. But anyway, it will be closed so don't plan on driving over it. Though generally taking it out of your commute altogether might not be such a bad idea.
