Merrimon Avenue does not need to accommodate more cars. It needs to offer more pedestrian space and safer bicycle traffic. It needs fewer lanes to cross, not more. It needs slower traffic, (20 MPH, maybe?), and a vigilant crack down on drivers texting! It is a dangerous place to walk and drive.
Years ago one of my 4th grade students at Claxton Elementary was killed in traffic because she did a poor job of crossing Merrimon Avenue at WT Weaver. There was no sidewalk from WT Weaver Road on the west side for far too long a distance. There’s still no sidewalk there. This is dangerous and has had fatal consequences.
Please do not turn four lanes into five. Turn them into three and add bike lanes and sidewalks. And don’t forget to plant trees along the way.
