The Kansas Highway Patrol has closed the eastbound lanes on K-96 at West Street. The fog has caused several traffic accidents and backups along K-96 and I-235.
Troopers are also working an accident in the eastbound ramp at I-235 and Meridian.
Wichita police are also working an accident at 37th and Ridge.
Sedgwick County dispatchers say traffic lights at many intersections this morning were malfunctioning because of the weather.
The fog can affect the way sensors work at intersections. The sensors switch to fog mode allowing the lights to change after a set amount of time. One red light can last about thirty seconds longer than when the sensors are in use.
Dirt in the air from vehicle emissions can add problems, too. When the fog and dirt combine, it dirties the senors' lenses. Road maintenance workers have to clean each lens by hand so the sensors can work properly again.
In the winter, it can take longer to clean the lenses because workers don't want to divert traffic when the roads are slick.
Only a little more than ten percent of intersections in Wichita use them.
The Kansas Highway Patrol is working at least two accidents along K-96.
So far there's no word of any injuries. Sedgwick County dispatchers say three semis are involved in an accident at K-96 and West street. The accident has forced troopers to shut the area down.
There have also been reports of several traffic lights around Wichita that are not working.
