Overturned tractor trailer inner loop after 270 spur

There is an overturned tractor trailer on the inner loop of I-495 after the exit to the I-270 spur (exit 38) and before Old Georgetown Road.  It closes two of the three lanes, keep to the right to get by.

Given how light traffic is on the outer loop, I don't know how much of a backup this is causing, but there are a steady stream of cars making their way past.  A crane is on the scene now preparing to pull the trailer back upright.
