Traffic delays are expected for today and Saturday at the intersection of 6th Street and Iowa Street for an overlay project. This photo looks to the north on Iowa St, toward intersection at 6th St.

Motorists may want to avoid Sixth and Iowa streets this weekend, as crews complete the final stages of an intersection rebuilding project.

This evening, crews will begin milling the intersection, and that will create some traffic issues. Crews will have to close Iowa Street where it connects to Sixth Street. Traffic will continue to be allowed on Sixth Street, but will be reduced to one lane in each direction. But motorists won’t be able to turn onto Iowa Street, and motorists on Iowa Street won’t be allowed to turn onto Sixth Street. The work is expected to begin around 7 p.m. and be done by 10 p.m., Chuck Soules, the city’s director of public works, said.

At 8 a.m. on Saturday morning, paving work will begin. During paving, Iowa Street access will be closed just like it was for the milling work. That work is expected to take place throughout the day. Traffic flow is expected to be back to normal by Saturday evening.

By next week, the bulk of the project is expected to be completed. When finished, the intersection will include a new left-turn lane for westbound motorists looking to turn south onto Iowa Street. The lack of a dedicated turn lane has been cited by engineers as the cause of several accidents over the years. The intersection also will have some additional right-turn lanes to improve traffic flow, Soules said.
