The U.S. Department of Transportation Federal Highway Administration has released its Environmental Impact Statement draft and among its many fascinating components is a listing of the accidents throughout the 14th Street Bridge corridor in both D.C. and Northern Virginia. This wide swathe of land includes many notable locations in both territories, from the National Mall to much of Arlington. The accidents were analyzed from January 2003 to August 2006, which is hardly recent but still points to many intersections fraught with vulnerability now.

Here's the most dangerous intersections, based on estimated severity rate:

The worst intersection is Washington, D.C.'s South Capitol and I Street:

South Capitol Street/I Street not only had the highest total number of accidents (80) but also the highest accident severity rating (139) of any intersection within the study area. Overall, the I- 395/VA 27 merge area had the highest severity rating (153).

What also stands out to me is where Independence Avenue connects with 14th Street. The percent of accidents that involve pedestrians and bicycles is 24%, drastically higher than any of the other dangerous intersections.
