re: I10 @ Causeway - Shutdown from 5AM to 3PM on Sunday (Posted on 1/18/12 at 6:48 pm to Schwartz)
They shut down traffic while they lift pieces of the new over cross spans so that no one is killed if a piece falls while being attached and inspected. You wouldn't typically see many people during this process. The actual lifting (erection) of the precast concrete and or structural doesn't take long. It is the completion of the welding at each connection that takes a while.
