Some residents at the Golden Terrance West Mobile Home Park have been told to evacuate after construction crews hit a gas line Tuesday morning.
Other people who live in the area have been told to stay indoors.
Xcel Energy has since shut off the gas line.
Street closures are still in place in the area of West 4th Avenue and Zeta Street.
People are asked not to call 911 about the gas leak unless there is a life-threatening situation, according to Golden Police.
