City officials wonder why the barricades are up after the state appears to have finished the project.
A rolled over car is stuck in a ditch at Lemont Road Monday morning, according to Illinois State Police.
The police department is surveying speeds on the street in question.
Part of the road will be closed for most of the summer, the city said.
The sharp curve may have been a factor in a 2021 motorcycle crash.
Some residents see this section of road as problematic, citing crashes.
Detours are expected during the work over the next month, the city said.
Completing part of job will require an additional cost to taxpayers, according to the county.
City decided on the light last year, citing crashes at the intersection.
The state explains what is going on and how long it will last.
The fence along the road continues to get hit, so a more permanent solution is needed, an alderwoman said.
Speeding is also seen as an issue on the street. The city said it is taking steps in response.
An alderwoman says the city wants a barrier next to the road.
A project to improve the intersection is set to start in early May, the county says.
Crews will begin work on the project which will take place at the Lemont Road Bridge along 1-55 that will continue through late 2023.
Parking will be allowed on Darien streets between 2 a.m. and 6 a.m. for a few nights around the Fourth of July.
