Earhart Expressway is 3 lanes (each way) in Jefferson Parish.
It drops to 2 lanes at the overpass at the Jefferson-Orleans line.
The plan proposes that Earhart Boulevard, passing through residential neighborhoods and across which school kids have to cross to get to public schools - be EXPANDED to 3 lanes (in each direction). Sidewalks could be right next to the streeet with no green space buffer.
Then at Carrollton the plan says Earhart widens to 5 lanes: 1 turning lane to go to the river, 2 turning lanes to go to I-10, and 2 to continue down Earhart.
Earhart narrows back to 2 lanes on the other side of Carrollton.

I can think of a better solution.
Keep Earhart 2 lanes in each direction.
Make certain there is green space between the sidewalk and the street.
Fix the traffic issue at Carrollton and Earthart
- with a marked and designated turning lane toward the river
- funnel traffic across Carrollton further down Earhart toward the city and provide a U-turn lane on the other side of Carrollton and then provide a designated Right Turn onto Carrollton at the Shell Station.

Oh yeah a designated right turn lane off of Carrollton onto Earhart (toward Jefferson) at the Popeye’s would fix evening traffic issues.
