1952,1988+1973 US-50 Chesapeake Bay Bridge at Annapolis, MD

(Bridge Hunter; no Historic Bridges; B&TSatellite)

"Original two-lane spans with through-truss suspension bridge and regular cantilever design built 1949-52 and opened 1952; second three-lane span with deck suspension and arched cantilever opened 1973; rehabilitated 1988" [Bridge Hunter Index]  The bridge rises 186' above the water. [BayDreaming

"When the Bay Bridge’s original span opened in July 1952, its 4.3 miles made it the world’s third longest bridge, as well as the world’s longest continuous over-water steel structure. Several superstructure sections of the bridge were built on barges and floated into place." [BayBridge] Once again, ABC (Accelerated Bridge Construction) is not a recent invention.

Like the other Chesapeake Bay crossing, you can hire someone to drive your car across the bridge. In this case, the height adds to the scariness.

Photo of the Ferry coming into Matapeake from the Eastern Shore at the same time the Chesapeake Bay Bridge was being built.
Charles L. Gallion: Matapeake IS on the Eastern shore. Looks like this ferry is coming into the docks on the western shore just south of Sandy Point.

The original bridge is on the right (South) and the additional bridge is on the left. The third lane on the newer bridge is reversible depending on traffic conditions. For example, people coming home from the beaches on a Sunday evening.

The new bridge has a massive cable-anchor pier at the end of the suspended span as would be expected for a suspension bridge. (Note the two bridge inspection trucks on the left side of this view.)
Street View

I had noticed that the pier at the end of the original suspended span was spindly. Looking closer, that is because additional cables go down to a concrete pier under the first truss span. That struck me as a clever (economical) design, I wonder why the new bridge did not do it that way.
Street View

Because the street view car was driving in the slow lane, I can't get a good view of the concrete pier and cable attachment. This photo shows that the pier for the truss next to the suspended span is solid concrete, as opposed to the pile piers for the other deck trusses, to provide an anchor for the cables.

Before heading into work this morning I took a walk on the beach to photograph the full moon setting over the bridge. Beautiful morning!

All chained down in the Annapolis anchorage area at sunset… 2/2/2024
That’s where they anchor while they wait their turn at the dock in Baltimore…
Mark Woods: They have schedule and if they dock early they have to pay so they wait but that is more than normal. David Sites is that right???
Jim Beirnes: Mark Woods way more than normal. Usually like 5 is max.

Building the westbound span of the Chesapeake Bay Bridge, September, 1972. (MDTA)

In the Google search results I saw some entries about a third bridge. Now I see a proposal for an 8-lane bridge to replace the existing bridges. [wbaltv] Just skimming some of the articles, the "need" for more capacity is to accommodate beach traffic. I think Federal money should pay for adding more lanes to I-80 through Joliet and replacing the Des Plaines River Bridges before it pays for some people having sun and fun on the beaches.

Allan Gilbert: I was supposed to be a deck engineer on a derrick like that, my union said no.

C Patrick Zilliacus: Looking east. On the right is the original two-lane span, opened in 1952. On the left is the "new" three-lane span, opened 1972.
The five lanes are set-up so that all traffic can be moved to one span if needed, running in two-way operation.
When there is heavy demand eastbound, one lane of the (normally) westbound span will run eastbound if weather conditions permit - this is generally done on weekday afternoons and on the day before a major beach holiday (Memorial Day, 4th of July and Labor Day)
Dan Murphy: Indeed there was 2-way traffic flow on the westbound span on this day. It's a creative operational maneuver in terms of maximizing the capacity of the spans, but it also highlights how antiquated the crossing has become.

November 22, 1978: A never ending job: A paint crew member straddles a steel I-beam underneath the old Chesapeake Bay Bridge in his constant task of painting the 4.5-mile structure. It takes five years and 30,000 gallons of silvery aluminum paint to cover the bridge from one end to the other. When that is accomplished, it’s time to start all over again.
Dave Frieder: Bridges are NEVER painted from end to end continuously. A bridge would be fully painted but even with today's modern non lead based paints they are only touched up over the years. After 15-20 years THEN they are full painted again.
