We advised metering that we were ready for taxi and would prefer 32R if available. Ground gave us clearance to taxi to 32R.

FAA Recommendation
A Federal Aviation Administration (FAA) recommendation stated, "Add the suggestion to our list of good operating procedures that closure strips should not be used as departure strip runway separators. Closure strips should be placed and left in a prominent position on the podiums. ... In addition to Locals and Grounds receiving runway closure strips, both Flight Data and Ground Metering should have closure strips as well. ... Revise Flight Data, Clearance Delivery, and Ground Metering positions relief checklists to include runway closure information. Brief operational personnel that runway closures must be broadcast on the ATIS. Brief operational personnel that pilots must be informed that a runway is closed when it is requested for takeoff/landing. Brief operational supervisors of the requirement to ensure ATIS broadcasts are correct and contain pertinent information."
