Just in time for spring comes word that the long-awaited 25-mile High Trestle Trail (previously known as the Ankeny to Woodward trail) north of Des Moines is almost completely ready for riding. Twenty miles of the trail – along a former rail bed – from Ankeny to Sheldahl and Slater to Madrid is largely finished. But the really cool part – the 13-story half-mile trestle bridge across the Des Moines River Valley, which would be one of the country’s largest trail bridges – won’t be done until next fall. T o be honest, I’ve long been unclear about when and where to ride this trail. See if you can figure it out from: a2wtrail.org.
