Gary L. Haller National Recreation Trail (Mill Creek Streamway Park) Better than ever By srwood1 in 9/27/2009 11:55:23 PM | The trail has recently been upgraded to address the few minor negatives mentioned. Signage has been added to mark the main trail. The one road crossing has been directed under a new bridge. The steep trail up the bluff now has a bypass for those looking to save time and energy. Also 911 emergency locator signs have been added for directing responders to exact locations along the trail. Throughout much of this trail, you would never know you were in a major city!
