Cracked bolts discovered during ultrasonic test

I-95 sign structure at Prince William Parkway

FAIRFAX—Beginning at 9 p.m. tonight, Feb. 17, the Virginia Department of Transportation will remove a 30-foot-tall cantilevered sign structure located on southbound I-95 at the Prince William Parkway in Woodbridge.  

Two cracked anchor bolts were discovered during an ultrasonic test earlier today. The test is part of VDOT’s ongoing investigation into what caused a similar sign structure to collapse onto I-66 last Saturday.

Over the past five days an inspection team has examined 25 of the 261 cantilevered signs in northern Virginia. The ultrasonic tests on all of these signs will be complete by March 30.

VDOT inspects its sign structures at least every five years.  Ultrasonic testing of the anchor bolts on the I-95 structure was performed in April 2008.  No problems were noted at that time. The structure that fell on I-66 was last inspected in December 2007 and ultrasonic testing of the anchor bolts was performed since the 2007 inspection.

Removal of the structure on southbound I-95 at Exit 158 will begin at 9 p.m. Two of three lanes will be closed but motorists can avoid delays by using the HOV lanes. State Police will be on the scene.
