A photo sent to ARLnow.com from an I-66 commuter shows a section of roadway that has sunk a foot or more, creating a large gap. In a tweet, DDOT says one lane is closed as a result.
That lane closure is causing big problems: even at 10:30 a.m. traffic on eastbound I-66 is very slow inside the Beltway, which in turn is causing backups on Arlington arterial roadways that lead to the highway.
In an email, a DDOT spokesman said the agency is investigating the issue.
