Right up there nudging close to Frank Gehry for the title of greatest living architect is Santiago Calatrava. (He’s working on the World Trade Center Transportation Center.) And just a day trip away is an example of his soaring work, albeit on a smaller scale. In Redding, of all places, visit the Sundial Bridge, a 700-foot long span for bicyclists and pedestrians. Anchored by a dramatic L-shaped pylon, it resembles a kind of monumental harp. Redding is 215 miles and fours away from SF if you take the 505 at Winter.
