Cracks in 13 cast-in-place pier caps supporting three bridges on the new Intercounty Connector toll highway in Maryland may be the result of a design flaw, according to the Maryland State Highway Administration.
More than 40 cracks—ranging in width from 0.005 to 0.035 in. and in length from 7 in. to 3 ft, 8 in.—were discovered during a routine MSHA close-out and acceptance inspection of the ICC's $2.56-billion, 7.2-mile first phase.
