Fort Belvoir’s commander on Friday said a major interchange is inadequate to funnel the glut of new traffic slated to arrive at the base in the next few years, part of an acknowledgment of the shortcomings of the I-95 corridor in light of a massive influx of military jobs.

Belvoir is now scrambling to prepare for the 2005 Base Realignment and Closure Commission directives, which call for 22,000 new workers to shift to the facility by 2011. Under a set of recommendations released Thursday, 18,000 of the workers would be placed at the 800-acre Engineer Proving Ground.
