With I-75 expanding in Charlotte County, some homeowners want a sound barrier wall.
FDOT says the area does not qualify, but neighbors tell WBBH-TV that the state has used data over a decade old.
A Freedom of Information request shows the state has not tested the sound in nearly 11 years.
Neighbors intend to organize again in an appeal to state leaders.
I-75 may have more lanes by next year.
