A part of I-70 in Missouri will not be named after a controversial historical site.
Governor Nixon has vetoed legislation that would have designated part of the highway as the "Graham's Picnic Rock Highway".
The rock sits in the median of I-70 between Columbia and St. Louis.
The rock was a popular spot in the 1880s for people to drive their horse and buggies to for picnics.
But Nixon says that location also has the name "slave rock" because it is believed that slave auctions also took place there.
Nixon says that the designation would have elevated one part of the areas history over another.
