YELLOWSTONE NATIONAL PARK, Wyo. (AP) — Road and parking area improvement projects are scheduled to begin the first week of July in Yellowstone National Park's Tower Junction and Canyon Village areas.

But the park says little impact is expected on visitors enjoying the summer season because most of the work will be during the night.

Crews will construct and widen a 2.5-mile stretch of road between Tower Junction and Tower Fall and reconstruct the Canyon Village parking lot.

The Tower Road work will result in closures from 11 p.m. to 7 a.m. into September. There could be 30-minute delays during open hours.

The Canyon Village Main Parking Area will be open during the day but closed from 11 p.m. to 6 a.m.

All stores will remain open for business during their normal operating hours.
