The Iowa Transportation Commission gave final approval Tuesday to a $315,000 grant for the reconstruction of the intersection of First Avenue South and 25th Street in Fort Dodge.
The grant award was first announced last summer.
That money will help to pay for creating right turn lanes on all four sides of the intersection. It will also help to pay for reducing part of South 25th Street from four lanes to three.
The intersection work, along with the burial of power lines and storm sewer improvements on First Avenue South between Veterans Bridge and 27th Street, is to be done next year.
Also on Tuesday, the commission awarded Fort Dodge a separate $50,000 grant that will help to pay for a traffic light study.
Each traffic signal in town will be analyzed as part of the study, according to Chad Schaeffer, the city's director of engineering, business affairs and community growth. He said the timing of traffic lights on Fifth Avenue South will also be reviewed.
Schaeffer said the city will earmark $60,000 from the local option sales tax to help pay for the study. A consulting firm will be hired to do the study, which is expected to be done during the spring and summer of 2014.
