A memorial vigil near the 800 block of South Maple Road turned violent after shots were fired around 8:30 p.m.

The road will be closed from east of South Maple Road to South Seventh Street for construction crews to remove and replace pavement; improve sidewalks, ramps and crosswalks; and work on public utilities.

Two construction projects will result in a lane shift on the west side and a road closure downtown through the middle of November.

Closures or lane shifts will range from a few weeks to six months.

South Maple Road will remain closed 24/7 until the project is finished on Friday, Jan. 21.
