发帖数: 2154 | 2 pittsburgh 的 Canton Avenue 居然第二啊。
Canton Avenue, in Pittsburgh, Pennsylvania's Beechview neighborhood, is the
steepest officially recorded public street in the United States
Canton Avenue may be steeper, but the Guinness Book of World Records says
Baldwin Street in New Zealand is the world's steepest.[3] Baldwin Street is
1,150 ft (350 meters) long and is said to include a grade of 35%. Canton
Avenue is 630 ft (192 meters) long (the hill is about 65 meters long) and is
claimed to include a 37% grade 6.5 meters long. | D********d

所以 我匹的 Canton Avenue 确实是offical 的美国第一。
The road is difficult and it’s a nightmare in the wet or dark (or both). It
links Waipio Overlook at the western end of Honokaa-Waipio Road (state
route 240), down into the Waipio Valley, in the Hamakua District. While the
road is now paved and only about ¾ mile long, the 25% average grade
(said to be up to 45% at some points), taking the road about 900 feet down
to the valley floor, is steep enough to destroy brakes on the way down, and
stall engines on the way up. The road is therefore restricted to 4x4s (which
you'll need anyway to navigate the unpaved roads on the valley floor), and
hikers with strong legs. This road is not for the faint at heart. It is a
forty-five degree angle all the way down and the only way to make it is with
4WD in low gear. It is a single lane road and folks going down have to
yield to folks coming up. |
