 There are challenges today for some drivers heading to Maryland's eastern shore, if that includes you. A sinkhole near the base of the Isle of Wight Bay Bridge temporarily closed the Ocean City Expressway, Maryland Route 9 yesterday. It did later reopen to controlled one-way traffic. Now Ocean City police say drivers will experience intermittent closures due to repairs near the base of the bridge. Drivers are being asked to use Route 50 and Delaware Route 54 as alternatives.
