Northbound I-35 exit ramp to East First Street in Ankeny to close Sunday night, July 21

GRIMES, Iowa – July 15, 2019 – 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.

The Iowa DOT reminds motorists to drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
