Question: Which documentary was made more recently, Exploratorium or The Bridge?
Context: Floating Bridge (Arabic: الجسر العائم‎ ‎ ) is a pontoon bridge (floating bridge) located in Dubai, United Arab Emirates.  The bridge was built between Al Garhoud and Al Maktoum Bridges mainly to reduce traffic in Al Maktoum Bridge.  The bridge connects across the intersection near Deira City Centre and Dubai Creek Golf & Yacht Club, and ends at the intersection to the Riyadh Street, between Dubai Courts and the Creek Park.  The bridge opened on 16 July 2007 where the project cost 155 million dirhams to build and has the capacity of 6,000 vehicles an hour.  The bridge also serve as an alternative route for Al Maktoum Bridge where Salik was recently implemented.  The Floating Bridge is the fifth crossing on the Dubai Creek while the others are Al Shindagha Tunnel, Al Maktoum Bridge, Al Garhoud Bridge and Business Bay Crossing. Charles Bridge (Czech: "Karlův most" ] ) is an historic bridge that crosses the Vltava river in Prague, Czech Republic.  Its construction started in 1357 under the auspices of King Charles IV, and finished in the beginning of the 15th century.  The bridge replaced the old Judith Bridge built 1158–1172 that had been badly damaged by a flood in 1342.  This new bridge was originally called Stone Bridge ("Kamenný most") or Prague Bridge ("Pražský most") but has been "Charles Bridge" since 1870.  As the only means of crossing the river Vltava (Moldau) until 1841, Charles Bridge was the most important connection between Prague Castle and the city's Old Town and adjacent areas.  This "solid-land" connection made Prague important as a trade route between Eastern and Western Europe. The Bridge is a 2006 British-American documentary film by Eric Steel spanning one year of filming at the famed Golden Gate Bridge which crosses the Golden Gate entrance to San Francisco Bay, connecting the city of San Francisco, California to the Marin Headlands of Marin County, in 2004.  The film captured a number of suicides, and featured interviews with family and friends of some of the identified people who had thrown themselves from the bridge that year. Aji Chy Bridge is one of the oldest bridges Northwest of Tabriz on the Aji Chay river.  This bridge was connecting Tabriz to the North of Azerbaijan.  It was also a major element in connecting East and Western parts of the Silk road.  The bridge has been restored and damaged numerous times during the course of history either by natural disasters or during the wars happened in the region.  The latest major reconstruction of the bridge was performed in the 19th century during Abbas Mirza's governorship by architect Hadj-Seyed-Hossein Tajer.  The bridge includes 16 spans with an overall length of 105 meters and width of 5 meters.  Due to several times of restoration and reconstruction the bridge doesn't have a uniform architecture.  Three spans out of 16 are semi circular shape while rest of the spans are in zig zag shape.  Recently the restoration of the bridge was performed by Iranian Organization of Cultural Heritages and registered in Iranian national heritages with number 2516. Gray's Ferry Bridge (more recently, Grays Ferry Bridge) has been the formal or informal name of several floating bridges and four permanent ones that have carried highway and rail traffic over the Schuylkill River in Philadelphia.  The bridge today is a four-lane divided highway bridge, built in 1976, that carries Grays Ferry Avenue from the Grays Ferry neighborhood on the east bank over the river and the Northeast Corridor railroad tracks to the Southwest Philadelphia neighborhood of Kingsessing.  An abandoned 1902 railroad bridge, the Philadelphia, Wilmington and Baltimore Railroad Bridge No. 1, sits just south of the highway bridge. Windsor Mills Bridge, also known as Wiswell Road Bridge or Warner Hollow Road Bridge, is a covered bridge that carries Covered Bridge Lane, formerly Wiswell Road, across Phelps Creek in Windsor Township, Ashtabula County, Ohio, United States.  The bridge, one of currently 17 drivable bridges in the county, is a single-span Town truss design.  The bridge sits atop cut stone abutments, one made of sandstone quarried nearby, and the other made of creek stone.  The bridge was bypassed in the 1960s and closed to traffic, and Wiswell Road was rerouted west of the creek.  In the 1980s, the bridge was completely closed due to safety reasons.  It underwent extensive renovation from 2002 to 2004, and was then reopened to all traffic, except for trucks and buses.  The bridge is listed in the National Register of Historic Places.  The bridge’s WGCB number is 35-04-25, and it is located approximately 5.0 mi (8.0 km) west of Orwell. Ned Kahn is an environmental artist and sculptor, famous in particular for museum exhibits he has built for the Exploratorium in San Francisco.  His works usually involves capturing an invisible aspect of nature and making it visible; examples include building facades that move in waves in response to wind; indoor tornadoes and vortices made of fog, steam, or fire; a transparent sphere containing water and sand which, when spun, erodes a beach-like ripple pattern into the sand surface.  In 2003 Kahn collaborated with Koning Eizenberg Architecture, Inc. on a piece for the Children's Museum of Pittsburgh consisting of hundreds of movable flaps that respond to the wind creating visible patterns.  Kahn won a MacArthur Foundation "genius grant" fellowship in 2003, and the National Design Award for environmental design in 2005.  His work is in the collection of di Rosa, Napa. Exploratorium is a 1974 American short documentary film about the Exploratorium science museum in San Francisco, produced by Jon Boorstin.  The film explores the museum through imagery and sound, without voice-over.  It was nominated for an Academy Award for Best Documentary Short. The Koshiji Bridge (越路橋 , Koshiji-bashi ) carries Japanese Kashiwazaki Takahama Horinouchi Line Road No. 23 in Niigata Prefecture.  The bridge replaced others on this site.  Possibly the most notable was a bridge originally constructed by Andrew Handyside & Co of Derby.  This bridge had been designed as a bridge for the Japanese National Railway in 1896 named "Shinanogawa Bridge" (信濃川橋梁) and saw good service until 1952.  In 1959 it was remodeled to be the "Koshiji Bridge" as a road bridge.  This was eventually made redundant when a bypass was constructed in 1998 and in 2002 the old Handyside bridge was shortened and moved to a park to preserve it. The Tour Eiffel Bridge, also known as the Montcalm Street Bridge is a small but ornate bridge in Gatineau, Quebec.  There had long been a bridge across Brewery Creek, but by the 1980s it needed to be replaced.  Hull and the National Capital Commission were working to turn the Brewery Creek area into a tourist and cultural district.  It was decided to build an ornate structure.  Incorporated in the bridge was an original steel girder from the Eiffel Tower, that had been part of a recently disassembled staircase.  The girder was donated to Hull by Paris mayor Jacques Chirac.  Architects Paul Martineau and Eric Haar modeled the bridge on Parisian style.  It opened in 1990.
