(Porter County, IN) - Portions of the Indiana Dunes National Park will have temporary closures for a few weeks.

Portage Lakefront and the Riverwalk area will be closed on weekdays from 7 a.m. to 4 p.m. beginning Monday.  That's a section of Dunes National Park adjacent to Ogden Dunes

Trucks will be delivering and installing large boulders needed to shore up the accessible ramp there.

The area will be open in the evenings after 4 p.m. and throughout the weekends.  The project is expected to be completed before Memorial Day weekend.

Several other nearby national park beaches will still be accessible during daytime hours.
