Skinker/McCausland is the "secret" shortcut that allows you to drive from north to south along the city/county border in record time. Bicyclists and walkers now have their own secret city/county path: the River Des Peres Greenway. The Great Rivers Greenway District has spent the past five years working for "a clean, green connected St. Louis region" through its River Ring of trails and parks. The newest section is the smartest shortcut, the greatest life saver (literally), and the most beautiful of all the district's efforts. The path begins with a limestone, brick mosaic and fleur-de-lis flourish at Holly Hills Avenue and Christy Drive, winds peacefully like a blacktop snake crossing Loughborough Boulevard and Germania Street, where a gigantic green metal bridge sweeps over the River Des Peres proper and safely deposits us onto the county line in one heaven-sent shortcut. It continues its pageantry of safety and beauty up River Des Peres Boulevard (one of the most dangerous roads for cars), crossing Gravois Avenue and Chippewa Street and ending at what will be the Shrewsbury MetroLink station. The planning of the paths is logical and clever, the execution is flawless in materials and aesthetics, and even though the project is not yet 100 percent finished, it's one of the most pleasing and useful journeys from city to county and back again.
