Construction to fix flaws in the recently completed Intercounty Connector could cause traffic slowdowns starting next week, Maryland officials warned.

Inspectors in the fall found premature cracks on bridges along the new $2.6 billion highway that now runs from Interstate 370 in Shady Grove to Interstate 95 in Prince George’s County. The affected overpasses are at Md. 97/Georgia Avenue, Emory Lane, Muncaster Mill Road and Needwood Road, officials said.
