The fire department, police and Delmarva crews were called out around 12:00 p.m. to the 900 block of North Shipley Street.
It was there that police say a gas line was struck during construction, which consequently lead to the leak.
That leak has since been secured and those evacuated were allowed to return.
All roadways have re-opened with the exception of the 900 block of North Shipley Street.
Delmarva remains at the scene.
