You might have noticed that the Margaret Hunt Hill bridge opened earlier this year, offering the newest, shiniest, most signature-y way to get across the Trinity River. No matter how high the arch or how famous the architect, no bridge can match the humble charm of the Houston Street Viaduct, best appreciated from a bicycle saddle. Embark from Oak Cliff over the arches of weathered concrete, the downtown skyline looming ahead. Nod to the gentleman with the tweed pageboy cap pedaling past. Puzzle at the eerily deserted Reunion Arena parking garage before finding yourself downtown, right next to Dealey Plaza. It feels like you've traveled a few decades back in time. Soon, it'll feel even more so; DART is planning for its Oak Cliff street car line to pass over the historic span.
