clusterfuckery on hwy 40

I find out my exit (to the courthouse) is closed right as I’m pulling up. There are no advance signs to warn me. Why would there be a sign??? It’s a left exit, of course, so I have to cross 4 lanes of traffic within 20 seconds to get to the next exit, which is the last Missouri exit. Fun times. Fun fucking times. Fuck you very much, Missouri Dept. of Transportation.
