A series of accidents shut down westbound I-66 near Sycamore Street this morning.
WUSA is reporting that the highway was closed from 5:00 to 6:30 a.m. due to multiple chain-reaction crashes caused by deer running onto the roadway.
Deer-vehicle collisions are becoming increasingly common in the United States. Between 2007 and 2009, the number of reported crashes involving deer rose 18.3 percent compared to the period five years prior.
