As part of the ongoing reconstruction of the Interstate 35 interchange at First Street in Ankeny, First Street will be closed at I-35 overnight from 12:01 a.m. until 5 a.m. Thursday and Friday, March 29 and 30, weather permitting, according to the Iowa Department of Transportation’s Grimes construction office.

The closure is necessary to allow to prepare for setting new bridge beams over First Street. Traffic on First Street will be detoured around the work zone using I-35, 36th Street (exit 94), and Oralabor Road (exit 90).
