A first vote looms tonight on a controversial school redisctricting plan in Fulton County.

School officials say it would ease classroom overcrowding, but critics say it would massively worsen overcrowding on area roads.

The plan would affect thousands of students.

The plan would shift the boundaries for Milton, Roswell, Alpharetta, and Johns Creek high schools, in advance of the opening of a new school in Milton in 2012.  Deciding who goes to the new school has many parents angry, as they complain about the traffic and about how students would become students at once-rival schools.

Earlier this month, parents staged a 50-car caravan down Crabapple Road to demonstrate how even a few extra cars could congest the traffic.

They say it took 30-minutes to get two miles!

But the traffic is not the only concern.

"The way it's splitting our community is just really dividing the kids' social networks, academic networks, not to mention the traffic pattern that is up the road," parent Kimberly Miller tells Channel 2 Action News.

Tonight's vote is a "first reading," which would accept the plan for review.

If it moves forward, a final vote would come next month.
