Route description
SR 417 begins at an intersection with SR 373 (Mooresville Highway/W Commerce Street) in the western part of the city. It heads north through wooded areas before curving to the northeast and passing through suburban areas, where it passes by Marshall County High School and Lewisburg Middle School. The highway curves to the east to pass by Westhills Elementary School before it comes to an end at an intersection with US 431 (N Ellington Parkway/SR 50/SR 106).[2] The entire route of SR 417 is a two-lane highway.[3]
Major intersections

gollark: Did you just randomly decide to calculate that?
gollark: Well, you can, or also "it would have about the same mass as the atmosphere".
gollark: Wikipedia says that spider silk has a diameter of "2.5–4 μm", which I approximated to 3μm for convenience, so a strand has a 1.5μm radius. That means that its cross-sectional area (if we assume this long thing of spider silk is a cylinder) is (1.5e-6)², or ~7e-12. Wikipedia also says its density is about 1.3g/cm³, which is 1300kg/m³, and that the observable universe has a diameter of 93 billion light-years (8.8e26 meters). So multiply the length of the strand (the observable universe's diameter) by the density of spider silk by the cross-sectional area of the strand and you get 8e18 kg, while the atmosphere's mass is about 5e18 kg, so close enough really.
gollark: Okay, so by mass it actually seems roughly correct.
gollark: So, spider silk comes in *very* thin strands and is somewhat denser than water, interesting.
