Thanks James. Your diagram makes it clear, but the photos show that A-8
still exists. Is it blocked off with barracades as other posters have
noted?

I don't know from personal experience, but the news reports on the day of
the accident included the following quote:

" The construction changes momentarily confused veteran pilot Lowell Wiley
two days before the Comair crash. He nosed his plane down the same taxiway
that he had taken for years until hitting a barricade.

"It was a total surprise," said Wiley, who adjusted course and got onto the
correct runway. He now understands why the Comair pilot might have headed
down a runway 1,500 feet (450 meters) too short to make a proper takeoff. "
