Calarogu Shark Media. Greetings trivia fans.

00:00:09.439 --> 00:00:12.880
I'm Mark Allison, and today we're celebrating the anniversary of
3
00:00:12.880 --> 00:00:16.079
one of America's most iconic structures.
4
00:00:16.000 --> 00:00:17.839
The Golden gate Bridge.
5
00:00:18.519 --> 00:00:21.879
Question one, In what year did the Golden gate Bridge
6
00:00:21.960 --> 00:00:28.280
open to the public, connecting San Francisco to Marin County?
7
00:00:29.199 --> 00:00:29.800
Question two?
8
00:00:29.920 --> 00:00:33.799
What distinctive color is the Golden gate Bridge painted? Which
9
00:00:33.880 --> 00:00:37.799
was specifically chosen to enhance its visibility in the fog?
10
00:00:43.200 --> 00:00:45.960
Question three? How long did it take to construct the
11
00:00:46.000 --> 00:00:49.759
Golden gate Bridge from groundbreaking to opening day?
12
00:00:54.359 --> 00:00:55.079
Question four?
13
00:00:55.479 --> 00:00:58.520
Who was the chief engineer of the Golden gate Bridge
14
00:00:58.520 --> 00:01:09.840
responsible for its design and construction? Question five? What surprising
15
00:01:09.920 --> 00:01:14.359
weather phenomenon did construction workers experience while building the bridge
16
00:01:14.599 --> 00:01:18.319
which created a rolling effect on the partially built structure.
17
00:01:20.799 --> 00:01:24.239
We'll be right back with these monumental answers after this break.
18
00:01:27.439 --> 00:01:32.159
Welcome back, trivia fans. Let's reveal today's answers. Question one,
19
00:01:32.680 --> 00:01:36.200
in what year did the Golden gate Bridge open? Answer?
20
00:01:36.400 --> 00:01:40.079
Nineteen thirty seven. The bridge officially opened to pedestrians on
21
00:01:40.159 --> 00:01:44.200
May twenty seventh, nineteen thirty seven, and to vehicular traffic
22
00:01:44.239 --> 00:01:47.359
the following day. The opening celebration lasted for a week,
23
00:01:47.719 --> 00:01:51.040
with over two hundred thousand people crossing the bridge on foot.
24
00:01:51.040 --> 00:01:55.200
On opening day, President Franklin D. Roosevelt officially opened the
25
00:01:55.239 --> 00:01:57.879
bridge to traffic by pressing a telegraph key in the
26
00:01:57.920 --> 00:02:01.319
White House, which transmitted a signal to San Francisco. The
27
00:02:01.359 --> 00:02:05.239
bridge connected San Francisco to Marin County, eliminating the need
28
00:02:05.280 --> 00:02:09.280
for ferry service across the Golden Gate Strait and fundamentally
29
00:02:09.319 --> 00:02:14.000
transforming transportation in the Bay Area. Question two, What distinctive
30
00:02:14.120 --> 00:02:15.840
color is the bridge painted?
31
00:02:15.919 --> 00:02:17.520
Answer? International orange.
32
00:02:17.919 --> 00:02:21.759
This reddish orange color was selected by consulting architect Irving
33
00:02:21.840 --> 00:02:26.639
Morrow because it complemented the natural surroundings while providing enhanced
34
00:02:26.759 --> 00:02:30.680
visibility in fog. The US Navy had initially wanted the
35
00:02:30.719 --> 00:02:34.599
bridge painted in black and yellow stripes to ensure visibility
36
00:02:34.599 --> 00:02:38.520
for passing ships. The color has become so iconic that
37
00:02:38.800 --> 00:02:43.199
it's officially known as Golden Gate Bridge International Orange and
38
00:02:43.319 --> 00:02:48.039
has a specific paint formula. The entire bridge is repainted continuously,
39
00:02:48.080 --> 00:02:51.439
with painters starting at one end and working their way across,
40
00:02:51.680 --> 00:02:54.680
then beginning again in a never ending cycle of maintenance.
41
00:02:54.719 --> 00:02:58.680
To protect the steel from the corrosive effects of salt Air.
42
00:02:59.240 --> 00:03:02.520
Question three, how long did it take to construct the bridge?
43
00:03:03.039 --> 00:03:03.400
Answer?
44
00:03:03.599 --> 00:03:08.400
Four years and four months. Construction began on January fifth,
45
00:03:08.800 --> 00:03:12.680
nineteen thirty three, and was completed in April nineteen thirty seven,
46
00:03:13.000 --> 00:03:15.879
with the bridge opening to the public on May twenty seventh,
47
00:03:16.240 --> 00:03:17.639
nineteen thirty seven.
48
00:03:18.000 --> 00:03:19.919
This was an impressive feat.
49
00:03:19.840 --> 00:03:22.840
Considering the engineering challenges and the fact that it was
50
00:03:22.879 --> 00:03:26.240
built during the Great Depression. The project came in under
51
00:03:26.240 --> 00:03:29.800
budget at a cost of thirty five million dollars twenty
52
00:03:29.879 --> 00:03:33.639
seven million dollars for the actual bridge structure, which would
53
00:03:33.680 --> 00:03:37.439
be approximately one point five billion dollars in today's dollars.
54
00:03:37.840 --> 00:03:40.560
It was financed by a bond issue, with the debt
55
00:03:40.599 --> 00:03:44.039
being repaid through bridge tolls, which were initially set at
56
00:03:44.080 --> 00:03:48.039
fifty cents each way, equivalent to about ten dollars today.
57
00:03:48.879 --> 00:03:54.159
Question four. Who was the chief engineer? Answer Joseph Strauss.
58
00:03:54.479 --> 00:03:57.960
Though he had never designed a suspension bridge before, Strauss
59
00:03:58.039 --> 00:04:00.759
championed the project for more than a dedaby deade against
60
00:04:00.800 --> 00:04:05.199
significant opposition. His initial design was heavily modified with the
61
00:04:05.319 --> 00:04:09.039
help of senior engineer Charles Alton Ellis and bridge designer
62
00:04:09.120 --> 00:04:14.800
Leon Moysief. Consulting architects Irving and Gertrude Morrow were responsible
63
00:04:14.840 --> 00:04:18.439
for the Art Deco elements and the distinctive color. Strauss
64
00:04:18.480 --> 00:04:21.480
remained the public face of the project and is widely
65
00:04:21.519 --> 00:04:25.040
credited as the driving force behind its completion. He wrote
66
00:04:25.040 --> 00:04:28.079
a poem titled the Mighty task is done for the
67
00:04:28.120 --> 00:04:31.319
bridge's opening, and died barely a year after its completion.
68
00:04:31.800 --> 00:04:35.600
Question five, What surprising weather phenomenon did workers experience?
69
00:04:35.680 --> 00:04:36.920
Answer? An earthquake.
70
00:04:37.399 --> 00:04:41.240
On June twenty second, nineteen thirty six, during construction, workers
71
00:04:41.279 --> 00:04:45.079
experienced a rolling earthquake while on the bridge. The partially
72
00:04:45.160 --> 00:04:49.879
completed structure swayed significantly but suffered no damage, validating the
73
00:04:49.879 --> 00:04:52.439
flexible design that allowed it to move up to twenty
74
00:04:52.480 --> 00:04:56.839
seven feet Laterally, the bridge was specifically engineered to withstand
75
00:04:56.920 --> 00:05:00.920
strong winds and seismic activity, with flexibilit being a key
76
00:05:00.959 --> 00:05:04.480
component of its design. This flexibility was put to a
77
00:05:04.560 --> 00:05:07.759
much more serious test during the nineteen eighty nine Loma
78
00:05:07.800 --> 00:05:11.680
Prieta earthquake, when the Golden Gate Bridge swayed but remained
79
00:05:11.720 --> 00:05:14.759
intact while other Bay Area bridges, including a section of
80
00:05:14.800 --> 00:05:20.000
the Bay Bridge, suffered significant damage. That concludes today's five
