I-395 14th Street Bridge Complex over Potomac River at Washington, DC

From upstream to downstream:

1960: (Bridge Hunter; Satellite) George Mason Memorial Bridge, southbound traffic

1968: (Bridge Hunter; Satellite) Rochambeau Memorial Bridge, HOV 3+ and toll traffic

1950: (Bridge Hunter; Historic Bridges; Satellite) 14th Street Bridge, northbound traffic

The 1950 14th Street Bridge was rebuilt in 1983 and renamed the Arland D. Williams, Jr. Memorial Bridge. The 1960 bridge was rehabilitated in 1984, and the 1968 bridge was rehabilitated in 1972 and again in 2001. So the older the bridge, the longer it lasted. (The 1968 bridge was rehabilitated in 1972 because of storm damage, but the other two bridges would have been subjected to the same storm.)

I'm not researching the two newer bridges because they are just UCEBs (Ugly Concrete Eyesore Bridges). The 1950 bridge is also a UCEB, but it had a movable span so it is of interest. "The bascule span no longer operates for boats, reportedly it last operated in 1982." [HistoricBridges]

In the background of this view we can see the swing span of the 1904 Long Railroad Bridge.

The predecessor to this bridge was a truss bridge with a swing span.

This is the 14th Street Bridge in Washington, DC. It is a bascule bridge that was built in 1950 and carries Interstate 395 over the Potomac River. The movable span no longer operates and is fixed in the closed position.
