The Francis Scott Key Bridge, more commonly known as the Key Bridge, is a six-lane reinforced concrete arch bridge conveying U.S. Route 29 (US 29) traffic across the Potomac River between the Rosslyn neighborhood of Arlington County, Virginia, and the Georgetown neighborhood of Washington, D.C. Completed in 1923, it is Washington's oldest surviving road bridge across the Potomac River.

The first Aqueduct Bridge was built in 1830 to carry the Chesapeake and Ohio Canal across the Potomac to connect with the Alexandria Canal on the Virginia shore.

The ceremony was held near Georgetown, at the canal's eventual 5.64 mi mark near Lock 6, the upstream end of the Little Falls skirting canal, and Dam No. 1.

- Chesapeake and Ohio Canal

Construction of the Chesapeake & Ohio Canal began in July 1828, to link Georgetown to Harper's Ferry, Virginia (West Virginia after 1863).

In 1949, the city constructed the Whitehurst Freeway, an elevated highway above K Street, to allow motorists entering the District over the Key Bridge to bypass Georgetown entirely on their way downtown.

The Aqueduct Bridge (also called the Alexandria Aqueduct) was a bridge between Georgetown, Washington, D.C., and Rosslyn, Virginia.

It was built to transport cargo-carrying boats on the Chesapeake and Ohio Canal in Georgetown across the Potomac River to the Alexandria Canal.

The bridge was closed in 1923 after the construction of the nearby Key Bridge.

The Potomac River surges over the deck of Chain Bridge during the historic 1936 flood. The bridge was so severely damaged by the raging water, and the debris it carried, that its superstructure had to be re-built; the new bridge was opened to traffic in 1939. (This photograph was taken from a vantage point on Glebe Road in Arlington County, Virginia. The houses on the bluffs in the background are located on the Potomac Palisades of Washington, DC.)

The Patowmack Canal was intended by George Washington to connect the Tidewater region near Georgetown with Cumberland, Maryland.

The Chesapeake and Ohio Canal operated along the banks of the Potomac in Maryland from 1831 to 1924 and also connected Cumberland to Washington, D.C. This allowed freight to be transported around the rapids known as the Great Falls of the Potomac River, as well as many other, smaller rapids.

a pod of 14 adults and young was followed up the river by men in boats as high as the Aqueduct Bridge (approximately the same location occupied by Key Bridge today).

The Alexandria Canal was a canal in the United States that connected the city of Alexandria to Georgetown in the District of Columbia.

In 1830, merchants from Alexandria (which at the time was within the jurisdiction of the federal District of Columbia) proposed linking their city to Georgetown to capitalize on the new Chesapeake and Ohio Canal (C&O Canal).

After the Key Bridge was completed in 1923, the old superstructure of the Aqueduct Bridge was removed.
