An aging bridge over a key East Hall artery — one that leads to East Hall Middle School — is scheduled to close Monday as work begins on a replacement structure. The new $1.2 million bridge on Joe Chandler Road over the North Oconee River, between Old Cornelia Highway and East Hall Road, is expected to open at the end of July, Hall County officials have said. School traffic should be OK on Monday, as officials are “planning to close (the bridge) shortly after 9 a.m. to allow (morning school) bus traffic to end,” Hall spokeswoman Katie Crumley said last week.
