Workers remove a large clamp from a section of pipe during construction of the Gulf Coast Project pipeline in Prague, Oklahoma, U.S., on Monday, March 11, 2013. The Gulf Coast Project, a 485-mile crude oil pipeline being constructed by TransCanada Corp., is part of the Keystone XL Pipeline Project and will run from Cushing, Oklahoma to Nederland, Texas.
