A gas line was broken in Seaside early Thursday, prompting evacuation of six businesses and block-long closures on Broadway Avenue and Fremont Boulevard.
A backhoe working on a service line to the City Center Plaza broke a gas line on Fremont about 11 a.m.
Police and fire crews responded.
"When we got there, there was a strong odor of gas in the entire area," fire Battalion Chief Chris Reitenour said.
Streets were closed for a block in each direction, and buildings were evacuated.
Firefighters found gas had gotten into a nearby building, which was emptied while the structure was ventilated, Reitenour said.
Everything reopened by 12:15 p.m.
"No one was hurt. It was mainly an inconvenience," Reitenour said.
