There are divided highways all over the country with traffic signals many with NO WARNING.
If it drives you crazy then perhaps it is time you gave everyone else a break.
Do a lower speed if that is what it takes too make you comfortable and if you cannot get comfortable find a different route. The road may not be up to design but it may be the only solution possible. Of course you could donate a lot of money to fund the needed (for you) improvements.
This is one of the problems today.Everyone wants government to do what they want because it is necessary, but if you are not a recipient of the benefit it must be wasteful and should be cut.
