No Cars Will Be Allowed on This Stately New Bridge in Portland

It was 1973 the last time a new bridge opened over Portland's Willamette River: a double-decker span with eight lanes of freeway. Times have changed. When the Tilikum Crossing Bridge opens later this year, it will be one of the few in the U.S. that's purpose-built for transit, bikes and pedestrians--no cars allowed.
