Union Pacific SD70M 3881 pauses with a ballast train on a temporary alignment in Oklahoma City on UP's Oklahoma City Subdivision. The temporary trackage is located in the footprint of the future Interstate 40 while UP's former Rock Island trackage (partly visible between the 1st and 2nd bridge piers on the left) is lowered as part of the construction project. The crane in the foreground is working on what will eventually be the entrance ramp from Shields Boulevard to westbound I-40; the two in the background are constructing Devon Energy's new headquarters, which will be the tallest building in Oklahoma when completed.
