History.
The causality land ferry company service, launched in 1867,
eventually became the Golden Gate ferry company, a sou-them pacific railroad
subsidiary, the largest ferry operation in the world by the late 1920. Once
for railroad passengers and customers only, sou-them specifics automobile
ferries become very profitable and important to the regional economy.
Preliminary discussions leading to the eventual building of
the Golden Gate Bridge were held on January 13, 1923, at a special convention
in Santa Rosa, CA. the Santa Rosa chamber was charged with considering the
necessary steps required to foster the construction of a bridge across the
Golden Gate by then Santa Rosa chamber president frank Doyle (the street Doyle
leading up to the bridge is named after him).
One June 12, the Santa Rosa
chamber voted to endorse the action of the “Bridging the Golden Gate
Association” by attending the meeting of the Boards of supervisors in San
Francisco on June 23 and by requesting that the board of Supervisors of Manson
country also attend. By 125, the Santa Rosa chamber had assumed responsibility
for circulating bridge petition as the next step fox the formation of the

Construction.
Construction began on January 5, 1933. The project cost more
than $35 million, completing ahead of schedule and under budget.
The project was finished and opened my 27, 1937. It was
completed $1.3 million under budget. The bridge round house diner was then
included in the southeast-em end of the golden gate bridge, adjacent to the
tourist plaza which was renovated in 2010.
Bridge round house, an art decor
designs by flared finial completed in 1938, traffic is separated by small,
plastic pylons, and from 1971 through 2007, there were 16 fatalities form
head-on collisions. To improve safety, the speed limit on the golden gate
bridge was reduced from 55 to 45 mph (89 to 72 km/h) on October 1, 1983.
In march 2008 the golden gate bridge district board approved
a resolution to start congestion pricing at the golden gate bridge charging
higher tolls during peak hours, but rising and falling depending on traffic
levels.
This decision allowed the bay area to meet the federal requirement to
receive $158 million in federal transportation funds us dot urban partnership
grant. An interview with Kevin hi ens who, as a 19 years old in 2000, survived a
suicide plunge from the span and is now a vocal advocate for some type of
bridge barrier or net to prevent such incidents.
