NOGALES, AZ (CBS5) -

Inspectors from the U.S. General Services Administration are studying the structural integrity of a tunnel that runs from Mexico into Arizona beneath the Dennis DeConcini Port of Entry in Nogales.

A cursory examination of the Grand Tunnel in 2014 raised questions about the structure's stability, but it wasn't until Arizona Senators John McCain and Jeff Flake sent a letter to the GSA in July that a true examination began.

The senator's letter states that officials from the City of Nogales are concerned that the tunnel is in jeopardy of collapsing. The letter also warns that monsoon season, with its possible torrential rains and flooding, could put the tunnel at further risk.

The remnants of Hurricane Newton are expected to hit Nogales late Tuesday night. Meteorologists are expecting between 2 and 9 inches of rain to fall on the area.

There are two main tunnels that run south to north, from Mexico into Arizona. They serve as drainage for underground rivers and washes that run northward because Nogales, Arizona sits at a higher elevation than Nogales, Sonora.
