The next phase of the Interstate 35/East First Street interchange project in Ankeny will include replacing the northbound I- 35 exit ramp to East First Street. Beginning Sunday, July 21 at 10 p.m., the ramp will be closed. The closure is expected to be in place until late August, weather permitting, according to the Iowa Department of Transportation’s Grimes construction office.

While the ramp is closed, motorists can follow a marked detour using northbound I-35, 36th Street, and southbound I-35 to access East First Street.

It is likely that while this ramp is closed, there may be traffic backups in this area.
