Gateway Arch National Park

Route 66 was certified in 1926, and St. Louis served as the eastern hinge of the Mother Road, with the Chain of Rocks Bridge carrying traffic across the Mississippi a few miles north. The Gateway Arch was conceived during that same Route 66 era. A 1933 civic committee led by Mayor Bernard Dickmann began clearing 40 city blocks of nineteenth-century warehouses along the riverfront to create a memorial. Saarinen won the 1947-48 design competition with his radical thin catenary, beating out his own father Eliel Saarinen in the same contest. Construction did not begin until February 12, 1963 because of postwar steel shortages and political fights over financing.

Generations of westbound Route 66 travelers had passed through St. Louis without a recognizable landmark to mark the start of their journey, navigating instead by the Old Courthouse dome and the riverfront cobblestones. The Arch, when it finally opened to the public on July 24, 1967, became the visual punctuation mark every cross-country motorist had been waiting for. Today, photos of Route 66 road trips almost universally begin or end here, and the National Park Service explicitly markets the monument as Mile Zero of the Mother Road. The 2026 Centennial planning includes a sunrise lighting program that bathes the stainless steel in copper tones to mark the route's 100th birthday.

Saarinen, who died in 1961 four years before his masterpiece was finished, calculated the curve using a weighted-chain catenary so the structure would carry its own weight through pure compression. The two legs were built simultaneously from concrete foundations 60 feet deep and met at the top within a tolerance of one sixty-fourth of an inch on October 28, 1965, after the south leg was cooled with fire hoses to shrink it the final fraction needed to mate with the keystone. No worker died during construction, which insurance actuaries had predicted would cost 13 lives.

Tram tickets are timed-entry and sell out daily, especially in summer and over holiday weekends, so reserve online at the official National Park Service e-store at least 48 hours ahead. Mornings between 9 and 11 am offer the shortest waits and the softest light over the riverfront for photos. Allow at least three hours total: 45 minutes for security screening and tram queue, 4 minutes up, 10-15 minutes at the top (the deck is small and gets crowded), 3 minutes down, then 90 minutes for the museum and Monument to the Dream documentary. Security screening is airport-style with metal detectors; large bags and outside food are not permitted inside.

Mobility considerations matter: while the underground museum is fully accessible, the tram pods are tight and require climbing into a low door. Visitors using wheelchairs can ride with assistance but should call ahead. The observation deck has narrow standing-only viewing slots, not seats. Strollers must be left at the base. Pair the visit with the adjacent Old Courthouse, where the original 1846 Dred Scott freedom case was first argued, and the new pedestrian land-bridge over I-44 that connects the park grounds directly to the downtown street grid. Both are included with the three-dollar park admission.

Photography is strongly encouraged everywhere except in the dimmed Monument to the Dream theater. The best exterior shot is from the Eads Bridge promenade looking south at golden hour, when the stainless steel turns molten orange. After dark, the arch is illuminated by ground-level LED arrays that occasionally glow in seasonal colors—blue for Cardinals home games, red and green at Christmas, rainbow during Pride weekend. The riverboat dock at the base operates the Tom Sawyer and Becky Thatcher replica paddlewheelers for one-hour Mississippi River cruises that depart hourly from April through October, offering a sweeping low-angle view back at the monument.

Most visitors come for the ride and miss that the National Park surrounds them with a 91-acre landscape designed by Dan Kiley, the modernist landscape architect who collaborated with Saarinen on the original 1947 master plan but did not see his vision fully realized until the 2018 CityArchRiver renovation. Allées of 200 tulip poplars frame the monument north and south, intentionally selected because their pyramidal shape echoes the arch's catenary. Two reflecting ponds mirror the curve on overcast days, and the Luther Ely Smith Square at the western edge connects the park to the Old Courthouse with a wide pedestrian boulevard where Route 66 vintage car shows gather every June for the National Road Trip Day rally.

The Old Courthouse, included in the park, is one of America's most historically significant buildings. It is where Dred and Harriet Scott sued for their freedom in 1846, where Virginia Minor argued for women's suffrage in 1872, and where the U.S. Supreme Court's eventual rulings shaped the trajectory of the Civil War and civil rights. The rotunda mural by Carl Wimar depicts the founding of St. Louis, and the restored 1862 courtroom is open daily with ranger-led programs every hour. The Courthouse closed in October 2023 for a two-year restoration and is scheduled to reopen in time for the Route 66 Centennial in fall 2026.

For the most underrated park experience, walk down the granite Grand Staircase to the cobblestone Mississippi levee, the only surviving stretch of nineteenth-century working waterfront in the American Midwest. The cobbles were laid between 1838 and 1880 to give horse-drawn wagons traction unloading steamboat cargo, and they are still the original Belgian-block stones. Stand at the river's edge and you are exactly where Pierre Laclède Liguest landed in February 1764 to found St. Louis, and exactly where every westbound pioneer began the overland journey that Route 66 later replaced with concrete and neon.
