Rochester used to have a lot more clover leafs in 1960. 🍀

Cloverleafs have fallen out of popularity due to the dangerous weaving conditions they create.

The Rochester Arterials were in many cases built early on in the Interstate era and have a lot of problems with weaving conditions and left handed exits and merges. Newer designs are better and they’ve been fixing them in recent decades.

Another interesting thing is the sharp curve at South Goodman Street on Interstate 490 – this is due to a sharp bend in the original Erie Canal which 490 follow, although they round a bit of the curve when they built the Interstate.

At the Can of Worms, the route of I 590 follows the original Erie Canal south bend – the sharp bend to the south from I 490 to I 590 was a feature of the Canal.
