I-30 between Dallas and Ft Worth.
On August 27, 1957 the highway was open to traffic, but the official opening came a week later on September 5. The turnpike's presence stimulated growth in Arlington and Grand Prairie and facilitated construction of Six Flags Over Texas. On December 31, 1977, the bonds were paid off and the freeway was handed over to the state Department of Transportation, toll collection ceased, and the tollbooths were removed during the following week.
Also, I-95 between Richmond and Petersburg, Virginia (aka the Richmond-Petersburg Turnpike); the tolls came off that stretch of 95 a while back. I was surprised they actually did it, as there are several other bridges and short connector highways in the Richmond area (VA 76/Powhite Parkway, VA 895 between I-95 and the Richmond International Airport, the Boulevard Bridge) that still have tolls on them and probably always will.
