According to the Texas Transportation Institute’s annual mobility reports, traffic delays due to congestion have been growing at nearly 8 percent per year since 1982. Those who closely scrutinize urban transportation planning in the U.S. increasingly believe that planners are doing everything they can to avoid solving this problem.
Case in point: Portland, Oregon, which sits astride the Willamette River and has ten roadway crossings of that river. One of them, the Sellwood Bridge, is structurally unsound and in 2004 the county engineer has banned all trucks and buses from the bridge. I can testify that the bridge is also one of the least bicycle-friendly bridges in the city.
