Crews will close one lane of eastbound Interstate 670 below the Grand Boulevard bridge Monday for lighting work.
The closure will be from 9 a.m. to 3 p.m. Monday. Similar work will require that westbound I-670 to be closed from 9 a.m. to 3 p.m. Tuesday.
Drivers looking to avoid the work on the south side of the downtown loop can use Interstate 70 on the north side of the downtown loop.
The bridge underwent an emergency closure May 6 after a Missouri Department of Transportation inspection revealed structural problems.
It’s still not clear what caused some large cracks to emerge precipitously, but the department determined the bridge needed to be demolished and replaced. A collaboration between the city and the state, plus good weather, helped speed up a project that normally takes several years, leading to completion in seven months.
