Roswell officials said two events Saturday could cause traffic problems.

The 4th annual Hembree Runs Wild 5K/1K race beginning/ending at Hembree Elementary School, 815 Hembree Road, will mean various closures on Hembree and Elkins roads between 7:50 and 9:15 a.m.

Also, the Roswell Beer Festival at Park Square will result in traffic congestion on Mimosa Boulevard.
