Type 3 Barricades or Type 1 Barricades?

Recently, on my campus I noticed a lot of type 3 barricades.  I knew they were type 3 because of the fact that there were 3 boards, but they were not as wide as I expected.  They may have been around 4 feet wide, while I am used to seeing type 3 barricades that are 6-10 feet wide.

At first I thought they were just type 1 barricades because of their width.  A type 1 barricade typically has 1 board while a type 2 has two boards.
