1,000ft tunnel between US and Mexico to be sealed A secret 1,000ft-long tunnel between the US and Mexico will be sealed after it was discovered earlier this month.
According to officials, the tunnel runs between the Mexican city of Ciudad Juarez and the US city of El Paso - which are separated by the Rio Grande and the US-Mexico border.
The CBP previously said that the tunnel measures six feet high and four feet wide, is fitted with lighting and a ventilation system, and is braced with wood throughout to prevent collapse.
US Customs and Border Protection (CBP) said its agents found a completed man-made tunnel after inspecting a storm drain system in Texas.
General Jose Lemus, commander of Ciudad Juarez's military garrison, said on Sunday that Mexican officials would seal the 1,000ft long underpass, according to CBS News.
