The Governor Thomas Johnson Memorial Bridge (also referred to as the Thomas Johnson Bridge and the Solomons Bridge) is a 1.37-mile (2.20 km) bridge in Maryland over the lower Patuxent River joining Calvert and St. Mary's counties. The bridge, named for the first governor of Maryland, Thomas Johnson, saw construction start in 1972 and opened to traffic on Dec. 17, 1977. The bridge, carrying an average of 33,000 vehicles a day on Maryland Route 4 (MD 4), is one of two crossings of the Patuxent River in Southern Maryland (the other is the Benedict Bridge approximately 20 miles up river, where MD 231 connects Calvert County and Charles County).

The north end of the bridge, on the Calvert side, is located in Solomons. Just prior to the bridge, MD 2-4 narrows from four lanes to two, and MD 2 exits the highway, passing under the bridge and heading toward downtown Solomons. MD 4 continues onto the bridge itself and over the Patuxent River.

The bridge, carrying two lanes and no shoulders, rises to a height of approximately 140 feet (43 m) tall, making a trip over the bridge in windy weather somewhat nerve-wracking for travelers. From the top of the bridge, one can see the entire town of Solomons, the runways at the Patuxent River Naval Air Station, and the Chesapeake Bay.

The bridge begins in St. Mary's County, before even reaching the Patuxent River. It passes over Town Creek first, then crosses over the unincorporated community of Spencers Wharf on a viaduct. Once over the community, the bridge passes over the Patuxent River, entering Calvert County. Shortly after reaching land, MD 2 joins MD 4 and cross Calvert County together for a long concurrency on a four-lane divided highway.
