Old Chain of Rocks Bridge

Old Chain of Rocks Bridge, St. Louis, MO

St. Louis, MO

A 1929 Route 66 bridge over the Mississippi, famous for the bend in its middle, saved from demolition and reborn as a walking and biking crossing.

The Old Chain of Rocks Bridge is one of the most beloved landmarks of old Route 66, a long steel span that carries walkers and cyclists across the Mississippi River just above St. Louis. Built in the 1920s, it once carried the Mother Road and its stream of cross-country travelers over the great river, and it is famous above all for one strange and wonderful feature: a sharp bend right in the middle of the bridge, an unexpected kink in the span that surprises everyone who crosses it.

The bridge is a survivor. When a newer highway bridge was built alongside it, the old bridge closed to cars and fell into disuse, and for years it faced demolition. Instead it was rescued and reborn as one of the longest pedestrian and bicycle bridges anywhere, and today crossing it on foot or by bike, high above the rolling brown Mississippi with the river and its wooded islands spread out below, is a favorite outing and a fine way to touch a piece of Route 66 history.

The bend in the bridge

What everyone remembers about the Old Chain of Rocks Bridge is the bend. Partway across the river the long, straight span suddenly angles, taking a sharp turn before continuing to the far bank, a kink almost never seen on a major bridge. The bend was built in for practical reasons tied to the riverbed and the alignment of the crossing, but the effect is delightfully odd, and walking toward it, watching the bridge turn beneath your feet, is part of the fun of the crossing.

The bridge itself is a handsome work of early twentieth-century engineering, a long ribbon of steel trusses marching across the wide river on tall piers. Its scale is impressive on foot, and the bend only adds to the sense of a structure with real character, a bridge that has kept its individuality across a century and become far more beloved for it than a plainer, straighter span ever could be.

A Route 66 survivor

For decades the Old Chain of Rocks Bridge carried Route 66 across the Mississippi, part of the famous highway that ran from Chicago to the California coast and carried generations of travelers, dreamers, and migrants west. Crossing the great river here was a milestone on that journey, and the bridge became woven into the lore of the Mother Road, a landmark remembered by countless people who drove it in the highway's heyday.

When the interstate era brought a new bridge nearby, the old span was closed to traffic and left to decay, and it came close to being torn down. Its rescue and reopening as a walking and biking bridge saved a genuine piece of American road history, and today it stands as one of the most cherished surviving landmarks of Route 66, a place where the romance of the old road meets the timeless power of the Mississippi.

The river and the water towers

From the bridge the Mississippi rolls past wide and strong, its muddy waters sliding around wooded islands, with the trees of the Missouri and Illinois shores stretching away on either side. It is a grand vantage on one of the great rivers of the world, and the crossing offers ever-changing views of the water, the sky, and the barge traffic that still works the river below.

Just upstream stand two curious structures that add to the scene: a pair of stone water intake towers rising from the river like little castles, built long ago to draw drinking water from the Mississippi. Their unexpected, fairy-tale appearance, glimpsed from the bridge, is a favorite sight, and together with the bend and the river they give the crossing a character all its own.

Walking and biking the bridge

Today the Old Chain of Rocks Bridge is open only to walkers and cyclists, and crossing it is free. It is a long span, so a full crossing and return is a good stretch of a walk or a pleasant easy ride, and on hot days it is worth bringing water and sun protection, as the bridge is open to the sky. The bend, the river views, and the water towers make the time pass quickly.

The bridge is also part of a growing network of riverside trails and greenways around St. Louis, so it can be enjoyed as a destination in itself or as part of a longer walk or ride along the river. Because it keeps day-use hours and access can vary, it is worth checking current information before you go, so you can plan a crossing of this one-of-a-kind Route 66 landmark over the Mississippi.
