There is an increasing use of sound barrier walls along sections of the interstate and along local roads. As I understand it, these walls are intended to reduce traffic noise in homes adjacent to the roadway. I can understand that, and there is a lot of information on design and effectiveness of these walls, but some have holes in them.
For example, there is a stretch of these panels along the south side of Ulmerton Road at the 113th Street intersection. About every fifth panel has what appears to be an access hole, about two feet in diameter, located about four feet above the ground. I have also noted similar holes on sound barriers along I-75 on the way to Sarasota after the I-275 junction. What purpose do these holes serve? I've researched these walls online, and can find no mention of these holes. Can you use your resources to find out what purpose the holes serve?
The openings are emergency access portholes used to fit fire hoses through.
