The Florida Department of Transportation began adding a concrete barrier to a section of Fort Lauderdale's beach to prevent further erosion, officials said.
Portions of the beach along State Road A1A were damaged Friday as swells destroyed sidewalks and pushed sand onto the street.
Fort Lauderdale Police, who had been issuing traffic advisories on their Twitter page, said the road's northbound lanes were once closed from Sunrise Blvd. to NE 20th Street, but just after 9 p.m., one northbound lane and one southbound lane were opened.
Authorities told NBC 6 that the National Weather Service said a low pressure system moving east was causing the northerly swells. Although the system will continue that movement, the waves were expected to decrease this weekend.
Aerial footage Friday showed waves splashing onto the street, bringing sand onto the roadway. In some areas of the beach, the waves reached the lifeguard towers.
Four to 5-foot swells were expected Friday along with 6 to 8-foot seas with possible breakers at around nine feet. Smaller swells are expected Saturday and Sunday, officials said.
