The pedestrian tunnel that crosses Route 1 in Crystal City will eventually be removed as part of the 23rd Street alignment project, though a scheduled closing has not been set.

The project, which is several years out, will “accommodate redevelopment on the east and west intersections of 23rd Street S. between Crystal Drive and S. Clark-Bell Street” in two phases. (Clark and Bell streets are also being realigned and merged into one.)

The tunnel may be closed before the project begins, “because it is underutilized” and because of upkeep costs, according to a county spokesperson. The tunnel was intended as a safety improvement, though many locals take their chances at street level due to the tunnel being dark and smelling like urine.

Robert Mandle, Crystal City Business Improvement District’s chief operating officer, cited several reasons for the change, including increased visibility for the row of restaurants along 23rd Street S. and what he called the “surprisingly common misconception that the tunnel will take you to Metro.”

“The interest in closing the tunnel really arises from the fact that most people use the surface crossing because the tunnel is longer, indirect, and uncomfortable,” Mandle wrote in an email to ARLnow. “Recent safety enhancements completed by Arlington County have further improved the existing signalized crossings.”
