Governor Pat Quinn has joined his Missouri counterpart and others at a ribbon-cutting for a new bridge over the Mississippi at Saint Louis.  The Stan Musial Veterans Memorial Bridge opened to traffic this past weekend.  The two states spent years fighting over how to pay for the $700 million span, then argued over what to name the bridge.  But on Saturday, officials from both states came together to celebrate its completion.  Quinn said the first new link to be built between downtown Saint Louis and southwestern Illinois in more than four decades will be a “catalyst for business development and job creation.”  U.S. Transportation Secretary Anthony Foxx called it “a road to opportunity.”  It’s designed to relieve Interstate 70 traffic on the chronically crammed 50-year old Poplar Street Bridge.
