EL DORADO HILLS, Calif -- Construction crews hit a gas line in El Dorado Hills this morning.

The tractor that hit the line on Gresham Drive got caught in a fireball, causing two workers to run for safety.

El Dorado Hills Fire Marshal Mike Lilienthal says one of the workers was taken to the hospital, not for burns, but just because he was shaken up.

The fire department is monitoring a controlled burn from the leak. Lilienthal says crews will have to dig up a part of the road to shut off the line.

Only two homes have been evacuated as a precaution.
