12th street is one of the most inconsistent (length & spur-wise) roads in Bloomington. It has several short sections on the northwest side, and a longer spur east of Walnut Street. Following the road from west to east, the first section starts at Oolitic Drive and ends after 2000 feet at a dead-end just after it crosses over Monroe Street. The next section is around 50 feet long and runs off of Blair Avenue. The next section runs for about 900 feet, starting only 100 feet from where it ended and running until it turns to the left just before the railroad tracks at Jackson Street. The fourth section starts at Walnut Street and goes about 3000 feet until it turns to the right and changes into Forrest Avenue.
