Leave well enough alone; money spent in places that are not really necessary....people using this road are used to it by now. I use it myself and got used to how it functions pretty fast within the first couple of times using it. It is very clearly indicated with yield signs. I find it works very smoothly. If it is not broken why try to fix it. Today’s society tries too hard to fix everything…we are spoiled. Honestly, give the money it will take to convert this, it put it where it counts.
