Tagaytay–Nasugbu Highway

The Tagaytay–Nasugbu Highway, alternatively known as Tagaytay–Nasugbu Road and formerly as Tagaytay–Tuy–Nasugbu Port Road, is a 43.86 km, two-to-four lane, secondary highway in the provinces of Cavite and Batangas, Philippines, that connects the city of Tagaytay in Cavite and the municipality of Nasugbu in Batangas.

The entire road forms part of National Route 410 (N410) from Tagaytay to Calaca and National Route 407 (N407) of the Philippine highway network from Calaca to Nasugbu.

Route description
The highway starts at Tagaytay Rotunda, where it intersects with Aguinaldo Highway, Tagaytay–Calamba Road and Tagaytay–Talisay Road in Tagaytay, Cavite. It then runs to the west along the Tagaytay Ridge, eventually traversing the boundary of Alfonso, Cavite and Laurel, Batangas. It then fully enters the province of Batangas, where it traverses north of Mount Batulao, the city of Calaca, and the towns of Nasugbu and Tuy. It re-enters Nasugbu, where it ends at the intersection with J.P. Laurel Street (Ternate–Nasugbu Road) and Nasugbu–Lian–Calatagan Road.

Alternate names
The highway's segment from Palico Rotonda to its western terminus in Nasugbu is also known as Palico-Nasugbu Highway or Tuy-Nasugbu Highway. Its segment in Cavite is also known as Emilio Aguinaldo Highway or simply as Aguinaldo Highway, named after General Emilio Aguinaldo, the country's first president and a native of Cavite. According to the Department of Public Works and Highways, its segment from its eastern terminus at Tagaytay Rotonda to the eastern end of Mahogany Avenue, both in Tagaytay, is part of the Tagaytay–Manila via Silang Road, while its segment from there to Diokno Highway is officially named as Tagaytay-Batangas via Tuy Road; the rest of the highway is officially named as is.

History
The highway originally existed as the Lumbangan–Palico (Nasugbu–Tuy) section of Batangas–Bauan–Nasugbu Road, an old road which linked Nasugbu with Batangas. The section was constructed in the mid-1910s. A new road that connects Tuy to the newly-established city of Tagaytay was later constructed in the 1930s and was made part of the highway. The latter also formed part of Highway 17 that linked Imus with Batangas. The entire stretch of the highway was also referred to as Tagaytay-Tuy-Nasugbu Port Road.
