ST. LOUIS (AP) - Tourists, commuters and downtown office workers are enjoying an unusual view of the Gateway Arch Thursday as a group of workers climb the iconic landmark in search of stains.
Workers could be seen rappelling down the Arch in a repair project commissioned by the National Park Service.
The Arch remains open, but public access to portions of its surrounding grounds is limited to the south entrance.
