Access to the trailhead where Mission Avenue dead ends at the Centennial Trail in Greenacres will be temporarily shut down today. As part of the Indiana Avenue extension project, crews are grinding down the paved portion of Mission and resurfacing it. Today crews will grade the unpaved portion of Mission and then spread the gravel-sized pieces of asphalt on the surface. It's a nice bit of recycling that will improve the dirt portion of Mission without too much efffort. As anyone who has driven that stretch lately can tell you, it was sorely in need of a good grading at the very least. And as an added bonus, the work is expected to widen the turn around where the street ends at the trail.
