I think "Way: 8915588" should be tagged `highway=motorway_link` rather than `highway=motorway`.

Way: 23809968 seems incorrectly tagged:
1. If it is construction, should be tagged `highway=construction`.
2. Based on the official site for this interchange project (http://www.circleinterchange.org/), it looks like this road is not under construction but is either permanently closed or is in the process of being permanently closed.

This section of highway, previous under construction, is now open to public (http://dc.gov/release/southeast-boulevard-reopens-between-11th-street-and-pennsylvania-avenue-se-barney-circle). In addition to access tags, it looks like some road geometries need to be updated.

It looks like this should not be footway=sidewalk.

It looks like this should not be footway=sidewalk.
