 There are challenges today for some drivers heading to Maryland's eastern shore. A sinkhole near the base at 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. Ocean City Police say drivers will experience intermittent closures due to repairs near the base of that bridge. Police are asking drivers to use Route 50 and Delaware Route 54 as alternatives.
