Controversy is brewing over a $75.6 million project that would expand westbound Interstate 66 in Arlington from two lanes to three over a 10-mile stretch. The main foe of the project: Arlington County.
As Eric M. Weiss reports for the Washington Post, project supporters say the roadway has become a regional chokepoint. Widening the road would improve traffic for commuters heading west in the evening, as well as reverse commuters heading for the Dulles corridor in the morning. But Arlington County leaders, who have opposed widening the Interstate inside the Beltway since it opened in 1982, argue that the project would simply replace existing chokepoints with others — at great expense.
Says Chris Zimmerman, a member of the Arlington County board of supervisors: “We’ve called for years for a multi-modal study to see what alternatives would be most effective in improving mobility in the I-66 corridor. All of that is being bypassed.”
I don’t know the particulars of Interstate 66, so I can’t comment on it. But the project reminds me of the clamor to build the Third Crossing in Hampton Roads. That crossing would tie into the existing Monitor-Merrimac bridge-tunnel just before it touches ashore in Newport News. The traffic from the two bridges then would funnel onto Interstate 64, which is already so congested that traffic routinely backs up for miles. From what I can tell, all the multi-billion dollar Third Crossing would do is move the chokepoint from the two existing bridge-tunnels to a point a few miles west on I-64.
Traffic projects must be evaluated in the context of the larger transportation system. When spot improvements can eliminate a bottleneck and restore free-flowing traffic, they may warrant funding. But when projects simply shift the location of bottlenecks from one location to another, they would seem to be an utter waste of money.
