Question: How long is the highway off of Wai' anapanapa Road where Wai' anapanapa State Park is located?
Context: The Hāna Highway is a 64.4 mi long stretch of Hawaii Routes 36 and 360 which connects Kahului with the town of Hāna in east Maui.  On the east after Kalepa Bridge, the highway continues to Kīpahulu as Hawaii Route 31 (the Piilani Highway).  Although Hāna is only about 52 mi from Kahului, it takes about 2.5 hours to drive when no stops are made as the highway is very winding and narrow and passes over 59 bridges, 46 of which are only one lane wide.  There are approximately 620 curves along Route 360 from just east of Kahului to Hāna, virtually all of it through lush, tropical rainforest.  Many of the concrete and steel bridges date back to 1910 and all but one are still in use.  That one bridge, badly damaged by erosion, has been replaced by a portable steel ACROW bridge erected by the United States Army Corps of Engineers.

Arden Valley Road is a scenic road located in Southfields, New York, in the United States, that travels through Harriman State Park and is owned by the Palisades Interstate Park Commission.  At 5.2 mi long, it begins at New York State Route 17 (NY 17) in Southfields and ends at Seven Lakes Drive in Harriman State Park.  Arden Valley Road also serves a trout stocking area for the Ramapo River.  The road is located entirely in Orange County and is home to the Elk's Pen Trailhead in Harriman State Park.  In 1921, plans arose by the commission to construct the road, which was completed the same year and stretched along the borderline with the Harriman estate.  Major William A. Welch ordered 75 elk from Yellowstone National Park to be placed in a wired cage between Arden and Southfields in 1919.  The elk eventually disappeared from the pen by 1942, and the area became the current Elk's Pen trailhead for trails within Harriman State Park. Maryland Route 119 (MD 119) is a state highway in the U.S. state of Maryland.  Also known as Great Seneca Highway, the highway runs 7.47 mi from MD 28 in Rockville north to Middlebrook Road in Germantown.  MD 119 is a four- to six-lane divided highway that connects several residential and commercial neighborhoods in Rockville, Gaithersburg, and Germantown.  Great Seneca Highway was planned by Montgomery County in the late 1960s as a local relief route for traffic on parallel Interstate 270 (I-270) between the three communities.  By the early 1980s, the highway had become controversial because it was proposed to pass through Seneca Creek State Park.  A coalition of civic and environmental groups unsuccessfully pursued litigation to stop the highway.  The National Park Service refused permission for the county to build the highway in 1985 but reversed itself two years later, by which time the first segment of the highway in Germantown was nearing completion.  The Rockville–Gaithersburg section was completed in 1989 and the controversial segment through the state park was finished in 1990.  Almost all of Great Seneca Highway became MD 119 in 1999.
