Underbuilt Intersections

[webny99]

I just got to thinking the other day that the intersection of NY 19 and NY 31 in Brockport, NY is severely underbuilt for the traffic volumes it handles. The left turns are near constantly backed up and poor signal timing doesn't help. It really needs two through lanes on each road, especially NY 31, and a double left from NY 19 SB onto NY 31 EB. The nearby NY 31/NY 260 intersection, for example, handles similar volumes but isn't nearly as bad of a chokepoint.

What are some of the most egregious underbuilt intersections that you can think of?

This intersection at 167th and Cicero in Oak Forest always gets my goat.

The left turn lane on 167th going westbound (left) ends immediately to the right of the picture. Although it appears average in length, it is not up to the task of handling the volume of left turning traffic that gets spat into the intersection from I-57.

167th has a short cycle, so the intersection gets clogged with queued cars that sprawl all the way back to the cloverleaf with I-57 as well.

There have been one or two times where I was stuck at this intersection going west for three signal cycles. IDOT should put in a double left turn lane and change this intersection from the configuration it was built in the early 70's.
