When exiting the Union Station Metro to eventually cross to the Capitol/Senate buildings, there is no explicit crosswalk, requiring pedestrians to "share" the road with traffic under a "Yield to Pedestrian" sign at the west end of the inner union station circle. There are now movable fences obstructing the crossing, causing pedestrians to walk further in the road. A permanent painted crosswalk should be installed, along with the Yield to Pedestrian sign and obstructions removed.
As it stands, there are very few crosswalks to the Columbus Circle plaza. Using the current painted crosswalks takes pedestrians going to 1st street far out of the way.
