Crews painting steel on the Interstate 430 and Interstate 630 interchange will require overnight lane closures next week.
The outside, eastbound lane and westbound, outside lanes of I-630 will be closed between 9 p.m. and 5 a.m. each night from Tuesday through next Friday.
Officials said the closure will occur between the I-430 southbound entrance ramp and the I-430 northbound entrance ramp.
