The truck route was closed due to a three-car accident that occurred late Monday afternoon.
"One of the vehicles actually rolled over," said Capt. Randy Foster of the Los Alamos Police Department. "Two people have been transported to the Los Alamos Medical Center with what appear to be non life-threatening injuries."
Truck route traffic was diverted to Trinity Drive, which remained backed up throughout the afternoon commute, as did the Main Hill Road.
Foster expected the truck route to reopen around 6 p.m.
