The massive Mississippi River navigation structure amazes visitors of all ages

ALTON, Ill. – Need a day-trip getaway? The St. Louis area has a lot to offer, including the Gateway Arch, Botanical Garden, a world-class zoo, City Museum, and baseball at Busch Stadium. Great places to visit, but rarely cheap and often crowded. There’s one hidden tourist gem offering spectacular views and educational opportunities on par with anything the big city has to offer.
The Melvin Price Locks and Dam is a navigational structure stretching four football fields shore-to-shore across the Mississippi River near Alton, Ill., a historic river city just north of downtown St. Louis. Maintained by the U.S Army Corps of Engineers, the purpose of the concrete and steel engineering feat is to aid large barge tows moving product up and down the river. The lock and dam – located south of the beautiful Clark Bridge and downtown Alton – is also home to the impressive National Great Rivers Museum.
Entry to the museum and tours of the lock and dam cost – nothing! That’s right, absolutely free. Tours begin inside the museum, where visitors sign-up for the 45-minute lock and dam tour (daily at 10 a.m., 1 and 3 p.m.). While waiting for the tour, enjoy the very impressive museum, which includes a lot of hands-on exhibits incorporating the history of Mississippi River life. But the real star of the show is the lock and dam tour.

An Army Corps guide leads visitors (via elevator) high above the bowels of the mega-structure. The scenic views of the river and surrounding area are unforgettable – simply amazing! The Clark Bridge upstream, the Gateway Arch downstream, Missouri to the west, Illinois to the east, and the power of the Mighty Mississippi beneath one’s feet is nearly overwhelming. Tour guides do an excellent job at describing each form and function of engineering – and can point out the variety of river wildlife swimming and flying nearby.
Visitors should arrive at least 15 minutes prior to a tour. Sign-up at the visitor desk. However, arrive an hour or so early to enjoy the museum. Tours on top of the lock and dam are exposed to the sky – no cover from the sun or wind. Bring an umbrella or hat on hot, sunny days. Cameras are allowed, but limited to a 200mm lens for 35mm digital SLR’s. The federal facility takes security serious – lockers are provided for bags. Keep photography low-key. Advice – leave everything in the car. Bring a phone for taking photos. A reasonably priced gift shop is in the museum. Snacks available.
To get there: Melvin Price Locks and Dam is located just south of Alton, Ill. along the Great River Road. Alton is located off Highway 67 north of Interstate 270. When you cross the Clark Bridge from Missouri, turn right (south) to the lock and dam.
