An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct may be made from a series of arches, although other more economical structures are typically used today.

Maryland Route 290 is a state highway in the U.S. state of Maryland. The highway runs 17.20 miles (27.68 km) from MD 300 at Dudley Corners north to MD 299 near Sassafras. MD 290 roughly parallels U.S. Route 301, which it intersects twice, as it connects the communities of Crumpton in northern Queen Anne's County and Chesterville and Galena in eastern Kent County. The portion of the route in Queen Anne's County was constructed as MD 301 in the early to mid-1920s. In Kent County, a portion south of Galena was built in the late 1910s and extended south to the Chester River in the late 1920s. MD 290 assumed the course of MD 301 in 1940 to avoid a number conflict with US 301. The Galena–Sassafras section of the highway was built in the late 1940s. MD 290 was reconstructed in Queen Anne's County and from south of Galena to Sassafras in the mid- to late 1950s. The highway's interchanges with US 301 were built when the U.S. Highway's course was constructed in the mid-1950s.
