The Homeland Security Department says the fence along the U.S.-Mexico border is mostly finished.
Customs and Border Protection spokesman Lloyd Easterling says that 601 miles of the project had been completed as of a week ago.
Easterling says 69 miles of the fence still must be built to meet the goal set during the Bush administration.
In December, then President-elect Barack Obama said he wanted to evaluate border security operations before he considers whether to finish building the fence under his administration.
Easterling said the Obama White House has not told Homeland Security to stop building the fence.
Homeland Security Secretary Janet Napolitano - the former governor of Arizona - has said a fence alone will not stop illegal immigration.
