The hours of operation for this checkpoint will vary, and MSP wants to stress that the idea behind letting the public know ahead of time is to lower anxiety.
When I was younger and more foolhardy, I had two car crashes here in Massachusetts that should have left me in worse condition than I ended up being in.
I mentioned in a post recently that it seemed like the MSP was getting serious in 2023 about warning the public about the dangers of drunk/impaired driving.
