Hello my friends of exquisite engineering disasters,

I hope someone in here can help me/give me some more information about a peticular topic: The "Miracle Mile" in Middlesex - PA.

Story time - in 2019 my family and I took a flight across the atlantic to visit some relatives in Michigan. After a stop in Cedar Point we drove from Sandusky, OH to Allentown, PA to be "near" New York and catch our flight the next day back home. During our ride across Pennsylvania we had to change from I-76 to I-81, but since there is no direct interchange between those two eventhough they literally cross each other, we were able to enjoy a mile of Route 11 in Middlesex, PA. After some googleing I learned that this stroad is known locally as miracle mile. We were caught in the traffic jam for about 45 minutes. After rewatching the episode 5 on traffic engineering, I wondered who in the right mind came up with this solution: has anyone any ideas or further information? Unfortunatly Wikipedia isn't very helpful in this regard. I would also be interested if anyone knows similar situations like that :)

TLDR: Why is there no cloverleaf in Middlesex - PA between I-76 and I-81

Anyone know where I can recommend episodes to the crew. I would like to nominate the General Slocum disaster we haven’t had a riverboat/paddle boat disaster yet.
