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. Friday, March 23, weather permitting, according to the Iowa Department of Transportation’s Grimes construction office.

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