Westbound state Route 52 near SR-163 was partially closed Thursday afternoon due to a fire on MCAS Miramar, Caltrans said.
The fire was reported at about 3:20 p.m. and quickly encroached on lanes of westbound SR-52 near Convoy, which prompted a full shutdown temporarily.
By 8:30pm Caltrans San Diego said "WB SR-52 west of SR-163, all lanes and ramps are now open to traffic."

MCAS Miramar firefighters were responding to the fire, which was about 5 acres and was not threatening any structures or prompting any evacuations, the military base said.
The fire was sending up a thick plume of light gray smoke as water tenders doused flames.
It was not immediately clear how large the fire was and what the conditions were in the area.
