What is a YOLT? Well, you may have heard the term YOLO. Gary and Sherri think we can live again, not as James Bond, but as being reborn. Consequently, we are having fun in our life, after all, You Only Live Twice.

Happy Isles Bridge

Pohono Bridge


Description:
So many bridges! Such long standing structures!. Looking down from Glacier Point you see them dotting the Valley, up close and as you walk over them, you enjoy views unmatched by almost all bridges in the world. We were able to either cross or see the following bridges:
  • Yosemite Creek Bridge—Pedestrians are no longer welcome on this narrow bridge. Still looking at the bridge, you admire how it looked.
  • Pohono Bridge—the bridge at the western end of the Valley. Usually the Merced River here is peaceful, leaving you to dream, whether it is Spring or Fall.
  • Happy Isles Bridge. The first bridge in the Valley where the Merced crosses under.


From the NPS Brochure on Yosemite Valley Historical Bridge:
The Yosemite Creek Bridge is the oldest, carrying the North Road and spanning Yosemite Creek below Yosemite Falls. Built in 1922, it spans 50 feet (15 m) in a single arch of reinforced concrete faced with granite. The bridge is 24 feet (7.3 m) wide, and was built at a cost of $32,000. The bridge originally featured lanterns on the buttresses at either end of the bridge.[2] It replaced an earlier bridge, referred to as "the little red bridge."[4]
The Ahwanee Bridge was built in 1928 across the Merced with three arches, one spanning 42 feet (13 m) and the others spanning 39 feet (12 m), for a total length of 122 feet (37 m). The bridge is 39 feet (12 m) wide with a 27 feet (8.2 m) roadway, a 5 feet (1.5 m) sidewalk and a 7 feet (2.1 m) bridle path. It carries the Mirror Lake Road, framing a view of Half Dome for eastbound traffic. Cost was $59,913.09.
The Clark Bridge was also built in 1928 with a single 75.5-foot (23.0 m) semi-elliptical main span flanked by two round-arched subways for horse-and-rider traffic, 7 feet (2.1 m) wide by 11 feet (3.4 m) high through the bridge's abutments. Cost was $40,061.22. The bridge carries the 27-foot (8.2 m) Curry Stables Road, a 5 feet (1.5 m) sidewalk and a 7 feet (2.1 m) bridle path.
The Pohono Bridge (1928) spans 80 feet (24 m), carrying the 27-foot (8.2 m) El Portal Road and a 5 feet (1.5 m) bridle path, at a cost of $29,081.55.
Pohono Bridge
The Sugar Pine Bridge (1928), also historically known as the Kenneyville Bridge No. 2, spans 106 feet (32 m) at a five-degree skew across the river, with a 27-foot (8.2 m) roadway, a 5-foot (1.5 m) sidewalk and a 7-foot (2.1 m) sidewalk. It carries the Mirror Lake Road. The longest span of the eight bridges, the cost was $73,507.44. The bridge was named for a large sugar pine that grew to the north of the east bridge abutment.[5]
The Tenaya Creek Bridge (1928) spans Tenaya Creek with a single 56.75-foot (17.30 m) arch at a 25-degree skew on the Happy Isles-Mirror Lake Road. The bridge carries the standard roadway, bridle path and sidewalk. Cost was $37,749.16.
The Happy Isles Bridge on the Happy Isles Road was built in 1929 with one span of 75 feet (23 m) and two equestrian subways in its abutments similar to those of the Clark Bridge, its near twin. The bridge's total length is 126 feet (38 m). Cost was $46,673.03.
The Stoneman Bridge (1933) resembles the Clark and Happy Isles bridges, with a 72-foot (22 m) main span carrying a 27-foot (8.2 m) road and two 6-foot (1.8 m) sidewalks. The equestrian subways in the abutments were slightly enlarged in width to 8.5 feet (2.6 m) and were extended out from the surface of the wing walls for greater emphasis. It is located at the Camp Curry intersection. Cost was $71,675.08.[2] The bridge replaced a wooden bridge that had carried the former "Royal Arch Avenue" to the Stoneman Hotel, which had been demolished by the 1920s. Construction on the bridge was started by Sullivan and Sullivan of Oakland, California, but was terminated when the Bureau of Public Roads lost confidence in the contractor's ability to carry out the work. The bridge was completed by the Portland, Oregon firm of Kueckenberg & Wittman.[6]
