The highway runs along a high ridge next to a valley with an airport. 'Lord Somnolent' notes: "Yield right of way to aircraft, please." 
Alongside the Wachusett Reservoir (drinking water for Boston), Interstate 190 features wide paved shoulders, intended to contain water and snowmelt runoff in its own drains rather than spilling into the reservoir. 
I-190 New York
28.34 miles ; from I-90 outside Buffalo to Niagara Falls. Trivia buffs: this is the only 3di that takes you to the Canadian border. It's called the "Niagara Thruway" between the starting point at I-90 and the North Grand Island Bridge. From there to the Canadian border, it has no name, but was called the Niagara Expressway by highway planners in the 1960s. 
On Aug. 14, 1957, AASHO unveiled a set of tentative interstate highway numbers for New York State, including I-90N for a spur from I-90 to Niagara Falls. On Aug. 22, 1958, the New York Department of Public Works submitted a plan including the same I-90N number for the Niagara Falls spur, and adding I-190 for a Buffalo North loop. At the time, today's I-190 would be called I-90N, and today's I-290 would be called I-190. 
On Aug. 29, 1958, AASHO responded with a change: the Buffalo North Loop should have an even starting digit, i.e. 290 instead of 190. On Feb. 24, 1959, AASHO approved changing the I-90N designation to I-190.  This was forward thinking in a way; though several letter-suffixed interstates were designated, AASHTO discourages the practice today, and all but two (I-35E/W in Minnesota and Texas) have been renumbered.
It was built in the mid-1950s, and uses sections of the North and South Grand Island Bridges that were built in the 1930s. Much of the highway through Buffalo was built on the former Erie Canal. There were plans in 1997 to turn I-190 into a surface parkway through downtown Buffalo, but this is said to have a slim chance of happening. 
I-190 South Dakota
1.72 miles ; south from I-90 into Rapid City. Dates back to 1962 or earlier.
