Arlington and the Virginia Department of Transportation are looking at how to improve the situation along the notably crash prone stretch of Route 50 (Arlington Blvd) between Glebe Road and Fillmore Street.

Between 2014 and 2018, VDOT said there were 247 total crashes with 61 crashes resulting in injuries, a few severe but none resulting in fatalities. Most of these crashes were concentrated around intersections.

“This segment of Route 50 experiences congestion in the morning and evening peak periods and a high number of crashes,” VDOT noted. “Route 50 averages 62,000 vehicles a day within the study limits.”

In an online presentation, VDOT proposed three alternatives with a variety of sub-options to cut down on conflict points — places where vehicles intersect. Two of the options would add new raised medians to Route 50, and each of them had sub-options that would limit left turns or turn Irving Street or Fillmore Street into one-way streets.

The three primary alternatives are:

• Wide Raised Median Separating EB and WB Route 50: the widened, raised medium would reduce conflict points at intersections without signals and at trail crossings. The only four-way intersections would be at Irving Street and Fillmore Street, where there are traffic lights. This alternative also includes left-turn lanes along Route 50 at Irving Street. The increased separation between eastbound and westbound travel lanes, and the additional turn lanes, would require the widening of Route 50.
• Narrow Raised Median Separating EB and WB Route 50: the narrower median accomplishes the same reduction in conflict points as the first alternative, but would also not include left-turn lanes at Irving Street, meaning there would be reduced widening requirements. Left-turns at Irving would be prohibited and the third lane would likely see more use. But while this plan would improve the situation at Irving Street, VDOT warned that it would not reduce conflicts at Fillmore Street and could create higher traffic volumes and delays there.
• No Left Turn at Unsignalized Intersections: the final alternative would add no median, but extensive signage prohibiting left turns along the street at all intersections without a signal. The widening impact would be low or non-existent, but VDOT warned that enforcing the new restrictions would be more difficult.

The sub-options to the first alternative include prohibiting any turning onto Irving Street and no left-turns at Fillmore Street, or flipping those so there are no left-turns onto Irving Street and no turning at all onto Fillmore Street.

Traffic signal improvements are also proposed.

VDOT data presented at the meeting said that two of the sub-options within the first alternative — which includes a wider raised median —  would have the highest chance of improving safety conditions, resulting in a total 69% reduction in conflict points, while the other two options reduce conflict points by 63%.

The first alternative is also the most costly, however, at an estimated $14-18 million budget. The second alternative, the narrow median, is cheaper at $12-14 million, while the third alternative is cheapest at $5-7 million.

“Cost estimates will be prepared for alternatives under consideration,” a VDOT official said in the video. “Improvements identified as part of the story have not yet been funded and there’s no timeline for construction”

Other potential additions to Route 50 would be new service roads along either side of the highway. One would be on the south side of Route 50 would extend past S. Old Glebe Road, which would eliminate five residential driveways onto the main lanes. The other would be on the north side of Route 50, extending an existing road west of Irving Street.

Comments on the project can be submitted online until Friday, May 29. Recommendations are scheduled to be finalized and posted online this summer, with Arlington County submitting a SMART SCALE funding application in August.
