ST. LOUIS, MO (KTVI) - U.S. Park service officials call it a condition assessment of the Gateway Arch. But, that might be an understatement of the Intrados. That`s the interior curved surface of the famous structure.
Monday, repellers were trying to go where no man has set foot before. Sunday a team was able to repel from the top of the 630 foot tall landmark down the North leg to the ground. Along the way, they checked every weld on that side.
A team of four people repelled down the North leg and were set to use guide wires and suction cups to continue down the interior curved surface to inspect some staining. The crew had to stop due to excessive heat from midday sun on the stainless steel skin of the arch.
Work will continue on the upside down weighted catenary arch Tuesday at 9am. A team will repel down the North leg to around 450 feet, then around the inside and down to the stain. The man will then have to climb all the way back to the 630 foot top of the arch.
