WASHINGTON — A new traffic analysis by the National Capital Region Transportation Board ranks some of the DMV's worst traffic spots. While the report offers a top 10 list of the region's worst areas for bottlenecks, Interstate 95 in Woodbridge, Virginia, reigns supreme.
According to the report, Southbound I-95 at VA-123/Exit 160 (near the Occoquan River) is "unrivaled as the region’s top bottleneck in both frequency and severity."
The northbound side of that same stretch of road is ranked No. 2 on the list.
Other top bottlenecks include Southbound DC-295 at East Capital Street coming in at No. 3, and the Baltimore-Washington Parkway northbound at Powdermill Road.
The analysis looked at traffic data over 12 years from 2010 to 2021. The particular stretch of I-95 appeared in the top 10 worst bottlenecks every year. Several other locations appeared in the top ten bottlenecks seven or more times in the 12-year period.

Elements that define a bottle neck for the purposes of the board's report are:
- A traffic queue upstream of the bottleneck
- A beginning point for a queue
- Free flow traffic conditions downstream of the bottleneck that have returned to nominal or design conditions
- As it pertains to an operational deficiency, a predictable recurring cause
- Traffic volumes that exceed the capability of the confluence to process traffic
